[PMID: 38830464 DOI: 10.1016/j.chemosphere.2024.142517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 05/05/2024] [Accepted: 05/31/2024] [Indexed: 06/05/2024]
Abstract
Indoor volatile formaldehyde is a serious health hazard. The development of low-temperature and efficient nonhomogeneous oxidation catalysts is crucial for protecting human health and the environment but is also quite challenging. Single-atom catalysts (SACs) with active centers and coordination environments that are precisely tunable at the atomic level exhibit excellent catalytic activity in many catalytic fields. Among two-dimensional materials, the nonmagnetic monolayer material g-C3N4 may be a good platform for loading single atoms. In this study, the effect of nitrogen defect formation on the charge distribution of g-C3N4 is discussed in detail using density functional theory (DFT) calculations. The effect of nitrogen defects on the activated molecular oxygen of Pt/C3N4 was systematically revealed by DFT calculations in combination with molecular orbital theory. Two typical reaction mechanisms for the catalytic oxidation of formaldehyde were proposed based on the Eley-Rideal (E-R) mechanism. Pt/C3N4-V3N was more advantageous for path 1, as determined by the activation energy barrier of the rate-determining step and product desorption. Finally, the active centers and chemical structures of Pt/C3N4 and Pt/C3N4-V3N were verified to have good stability at 375 K by determination of the migration energy barriers and ab initio molecular dynamics simulations. Therefore, the formation of N defects can effectively anchor single-atom Pt and provide additional active sites, which in turn activate molecular oxygen to efficiently catalyze the oxidation of formaldehyde. This study provides a better understanding of the mechanism of formaldehyde oxidation by single-atom Pt catalysts and a new idea for the development of Pt as well as other metal-based single-atom oxidation catalysts.

Abstract
One of the most efficient ways for the photogenerated charge carriers is by the development of heterojunction between p-type and n-type semiconductors, which creates an interfacial charge transfer between two semiconductors. By enhancing the bifunctional characteristics for hydrogen generation via photocatalytic and electrocatalytic water splitting reaction, we report the type-II Cu2O/g-C3N4 heterostructure in this article. Due to significantly increased catalytically active sites for the hydrogen evolution reaction (HER) reaction during electrocatalysis and decreased charge transfer resistance, the as-prepared heterostructure exhibits a lower overpotential of 47 and 72 mVdec-1 for the HER and oxygen evolution reactions (OER), respectively, when compared to alone g-C3N4. In addition, Cu2O/g-C3N4 heterostructures have a higher photocatalytic hydrogen evolution of 3492 µmol gcat-1 in the presence of Triethanolamine as a sacrificial agent, which is nearly 2-fold times greater than g-C3N4 (1818 µmol gcat-1) after 5 h of continuous light-irradiation. Moreover, produced heterostructure exhibits 81% of Faradaic efficiency and 18% of apparent quantum yield. This work successfully explains how the rise in water splitting is induced by the transfer of photogenerated electrons in a cascade way from p-type Cu2O to the n-type g-C3N4 using density functional theory (DFT) calculations.

Abstract
Developing and implementing visible light active organic-inorganic hybrid semiconductor nanomaterials with enhanced photocatalytic properties find newer environmental and energy treatment capabilities. Here, we are reporting polymeric g-C3N4 layers coated with different propositions of erbium oxide nanoparticles, characterized using XPS, UV-Vis-DRS, FT-IR, HR-TEM, FE-SEM, elemental mapping, XRD and surface area techniques and its photocatalytic activities were evaluated under visible light irradiations. The hybrid nanocomposite materials possess better crystalline nature and erbium oxide particles were on the surface of polymeric g-C3N4. The surface area and bandgap energy of the polymeric g-C3N4-erbium oxide (5 wt%) nanohybrid composite were 99.9 m2/g and 2.52 eV. The photocatalytic activities as prepared nanohybrid composites were assessed for the oxidation of orange G dye molecules in the presence of visible light and were highly active in a broader range of pH with the presence of various inorganic anions. The rate of photocatalytic oxidation of dye molecules varied from 4.79 × 10-4 to 1.77 × 10-4 min-1 for the initial concentration of 5 to 20 ppm and retained its activities above 95% up to three cycles of reusability. Hence, the organic-inorganic novel catalytic nanohybrid composite may find more comprehensive applications in the area of environmental and energy applications.

Abstract
The van der Waals heterostructures fabricated in two semiconductors are currently attracting considerable attention in various research fields. Our study uses density functional theory calculations within the Heyd-Scuseria-Ernzerhof hybrid functional to analyze the geometric structure and electronic structure of the g-C3N4/BiOBr(001) heterojunction in order to gain a better understanding of its photocatalytic properties. The calculated band alignments show that g-C3N4/BiOBr can function as a type-II heterojunction. In this heterojunction, the electrons and holes can effectively be separated at the interface. Moreover, we find that the electronic structure and band alignment of g-C3N4/BiOBr(001) can be tuned using external electric fields. It is also noteworthy that the optical absorption peak in the visible region is enhanced under the action of the electric field. The electric field may even improve the optical properties of the g-C3N4/BiOBr(001) heterostructure. Given the results of our calculations, it seems that g-C3N4/BiOBr(001) may be significantly superior to visible light photocatalysis.

Abstract
Semiconductor photocatalytic materials have shown potential in the field of antifouling due to their good antibacterial properties, stability, and nontoxic properties. It is an effective way to use them to improve the static antifouling performance of silicone antifouling coatings. g-C3N4/TNTs/CNTs (CNTC) photocatalytic composite powders were prepared and introduced into polydimethylsiloxane (PDMS) coatings to enhance their antifouling performance. Firstly, g-C3N4/TNTs with heterostructure were thermally polymerized by urea and TiO2 nanotubes (TNTs), and then g-C3N4/TNTs and multi-walled carbon nanotubes (CNTs) were composited to obtain CNTC. Finally, CNTC was added into PDMS to prepare g-C3N4/TNTs/CNTs/PDMS (CNTC/P) composite antifouling coating. The results showed that CNTC successfully recombined and formed a heterostructure, and the recombination rate of photogenerated carriers decreased after recombination. The addition of CNTC to PDMS increased the hydrophobicity and roughness while reducing the surface energy (SE) of the coatings. CNTC could effectively improve the anti-attachment performance of PDMS coatings to bacteria and benthic diatom. The bacterial attachment rate (AB) and benthic diatom attachment rate (AD) of CNTC/P-20 were, respectively, 13.1% and 63.1%; they are much lower than that of the coating without photocatalytic composite powder. This coating design provides a new idea for developing new “efficient” and “green” photocatalytic composite antifouling coatings.

Abstract
Background:
Rapid escalation in textile, paper, pesticides, pharmaceuticals and several other chemical based
manufacturing industries due to amplification in human requirements have proportionately contributed to the extreme
contamination of water ecosystem, resulted from the discharge of toxic pollutants from industries. Effluents from textile
industries are comprised of coloured dyes like Rhodamine B, Methyl Orange, Methylene Blue and phenolic compounds
which deserve special mention owing to their non-biodegradable, carcinogenic and severe detrimental nature. Urgent
needs to ameliorate this fast declining environmental situation are of immense necessity in current scenario.
Objectives:
Objectives: In this regard, graphitic carbon nitride (GCN) is a distinguished material for water purification-based
applications because of its exclusive characteristics making it highly prospective for degradation of toxic dyes from water
by catalysis and adsorption techniques. GCN has been a material of conspicuous interest in recent times owing to its two
dimensional sheets like structure with favourable surface area, and cost-effective synthesis approaches along with high
production yield. This article presents a detail study of different aspects of GCN as a material of potential for water
purification. Through extensive literature survey it has been shown that GCN is an effective material to be used in the
fields of application. Several effective procedures like catalysis or adsorption for removal of dyes from water have been
discussed with their basic science behind.
Conclusions:
This systematic effort shows that GCN can be considered to be one of the most efficient water purifier with
further advantages arising from its easy and cost effective large scale synthesis.

Abstract
This work aims at reviewing the most impactful results obtained on the development of Cu-based photocathodes. The need of a sustainable exploitation of renewable energy sources and the parallel request of reducing pollutant emissions in airborne streams and in waters call for new technologies based on the use of efficient, abundant, low-toxicity and low-cost materials. Photoelectrochemical devices that adopts abundant element-based photoelectrodes might respond to these requests being an enabling technology for the direct use of sunlight to the production of energy fuels form water electrolysis (H2) and CO2 reduction (to alcohols, light hydrocarbons), as well as for the degradation of pollutants. This review analyses the physical chemical properties of Cu2O (and CuO) and the possible strategies to tune them (doping, lattice strain). Combining Cu with other elements in multinary oxides or in composite photoelectrodes is also discussed in detail. Finally, a short overview on the possible applications of these materials is presented.

Abstract
Benzylamine coupling is a very important reaction for the synthesis of imine but still faces many challenges. Herein, we present a highly effective strategy towards the coupling reaction by using environmentally friendly catalysts. These catalysts are composed of Cu/Cu2O/Cu3N heterostructures supported by C3N4 tubes and the composites were synthesized by one-step hydrothermal treatment followed by calcination. Cu2O, Cu3N, and C3N4 all are responsive to visible light and the heterojunction formed can greatly enhance the charge separation. When used as photocatalysts for oxidative self-coupling of benzylamine at a low temperature of 323 K in air, Cu/Cu2O/Cu3N/C3N4 was able to give conversion and selectivity values of up to 99% and 98%, respectively. The high efficiency of the catalysts is attributable to their ability to generate large quantities of free radicals (such as ·OH and ·O2−) under visible-light irradiation. Cu/Cu2O/Cu3N heterostructures supported C3N4 tubes were synthesized by one-step hydrothermal treatment followed by calcination, which showed enhanced photocatalytic activity for oxidative self-coupling of benzylamine under visible-light.![]()

Abstract
Photocatalytic activity of low band gap semiconductor largely restrained by high recombination rate of photogenerated charge carriers. To enhance the catalytic performance numerous protocols were adopted amongst which designing of novel hybrid via coupling of semiconductors are very intriguing from modest application point of view. Here, we report facile realization of type II heterojunctions embracing polymeric graphitic carbon nitride (g-C3N4/GCN) and all-inorganic cesium lead halide perovskite (CsPbBrCl2) for degradation complex organic effluents under visible-light illumination. Synthesized hybrid presented much improved performance in toxic cationic and anionic dyes degradation as compared to individual building units. Signature of favorable staggered gap junction's formation at interface was confirmed via Mott-Schottky analysis. Such kind of junctions delay the recombination of photogenerated electron holes and facilitates active radical generation at catalyst surface thereby ensures improved photocatalytic performance. Charge transfer process in heterojunction further illustrated via Density functional theory (DFT) based calculations. Several scavenger tests have been performed to examine the impact of different active radicals in the photocatalysis which suggests manifold performance improvement in the presence of very small concentrations of EDTA. A plausible photocatalytic mechanism in accordance with the type II junction has been proposed.

Abstract
A highly porous architecture of graphitic carbon nitride g-C3N4/Cu2O nanocomposite in the form of cubes with a side length of ≈ 1 μm, large pores of 1.5 nm, and a high surface area of 9.12 m2/g was realized by an optimized in situ synthesis protocol. The synthesis protocol involves dispersing a suitable "Cu" precursor into a highly exfoliated g-C3N4 suspension and initiating the reaction for the formation of Cu2O. Systematic optimization of the conditions and compositions resulted in a highly crystalline g-C3N4/Cu2O composite. In the absence of g-C3N4, the Cu2O particles assemble into cubes with a size of around 300 nm and are devoid of pores. Detailed structural and morphological evaluations by powder X-ray diffraction and field emission scanning electron microscopy revealed the presence of highly exfoliated g-C3N4, which is responsible for the formation of the porous architecture in the cube like assembly of the composite. The micrographs clearly reveal the porous structure of the composite that retains the cubic shape of Cu2O, and the energy-dispersive spectroscopy supports the presence of g-C3N4 within the cubic morphology. Among the different g-C3N4/Cu2O compositions, CN/Cu-5 with 10% of g-C3N4, which is also the optimum composition resulting in a porous cubic morphology, shows the best visible light photocatalytic performance. This has been supported by the ultraviolet diffuse reflectance spectroscopy (UV-DRS) studies of the composite which shows a band gap of around 2.05 eV. The improved photocatalytic performance of the composite could be attributed to the highly porous morphology along with the suitable optical band gap in the visible region of the solar spectrum. The optimized composite, CN/Cu-5, demonstrates a visible light degradation of 81% for Methylene Blue (MB) and 85.3% for Rhodamine-B (RhB) in 120 min. The decrease in the catalyst performance even after three repeated cycles is less than 5% for both MB and RhB dyes. The rate constant for MB and RhB degradation is six and eight times higher with CN/Cu-5 when compared with the pure Cu2O catalyst. To validate our claim that the dye degradation is not merely decolorization, liquid chromatography-mass spectroscopy studies were carried out, and the end products of the degraded dyes were identified.

Abstract
In this article, we have judiciously interfaced copper oxides with graphitic carbon nitride (g-C3N4) from thermal reaction of melamine and copper sulfate in a one-pot protocol and manipulated the perforated sheet morphology thereafter. The CCN-X (X = 30, 40, 50, 60, and 70, depending on the wt % of CuSO4·5H2O) nanocomposites were prepared by homogenously mixing different percentages of CuSO4·5H2O with melamine from a solid-state thermal reaction in a furnace in air. Drastic lowering of CuSO4 decomposition temperature due to Cu(II)-amine complex formation and subsequent reduction of Cu(II) species by in situ produced ammonia (NH3) resulted in the production of CuO and catalytic amount of Cu2O, homogeneously dispersed within the perforated g-C3N4 nanosheet. How perforated sheet morphology evolved by combined effect of NH3, released from thermal condensation of melamine ensuring two-dimensional (2D) growth, and sulfur trioxide (SO3), expelled from CuSO4·5H2O facilitating the perforation, yielding better catalytic performance, has been elucidated. Excess NH3 from added NH4Cl removed perforation and ensued a marked decrease in efficacy. However, a high proportion of CuSO4·5H2O ruptured the framework of 2D sheets because of excess SO3 evolution. Among the different nanocomposites synthesized, CCN-40 (CuO-Cu2O/g-C3N4) showed the highest catalytic activity for 4-nitrophenol reduction. Thus, enhanced efficiency of the copper oxide catalyst by interfacing it with an otherwise inactive g-C3N4 platform was achieved.

Abstract
Rapid recombination of photoinduced electron-hole pairs is one of the major defects in graphitic carbon nitride (g-C3N4)-based photocatalysts. To address this issue, perforated ultralong TiO2 nanotube-interlaced g-C3N4 nanosheets (PGCN/TNTs) are prepared via a template-based process by treating g-C3N4 and TiO2 nanotubes polymerized hybrids in alkali solution. Shortened migration distance of charge transfer is achieved from perforated PGCN/TNTs on account of cutting redundant g-C3N4 nanosheets, leading to subdued electron-hole recombination. When PGCN/TNTs are employed as photocatalysts for H2 generation, their in-plane holes and high hydrophilicity accelerate cross-plane diffusion to dramatically promote the photocatalytic reaction in kinetics and supply plentiful catalytic active centers. By having these unique features, PGCN/TNTs exhibit superb visible-light H2-generation activity of 1364 µmol h-1 g-1 (λ > 400 nm) and a notable quantum yield of 6.32% at 420 nm, which are much higher than that of bulk g-C3N4 photocatalysts. This study demonstrates an ingenious design to weaken the electron recombination in g-C3N4 for significantly enhancing its photocatalytic capability.

Abstract
Mesoporous micro-/nanostructures acting as supports for catalysts or used directly in catalysis reactions generally show fascinating performances that could lead to great potential for application. In the past few decades, extensive efforts have been devoted to the exploration and enrichment of graphitic carbon nitride (g-C3N4) based research. Especially, mesoporous g-C3N4 (mpg-C3N4) with controllable porosity and electronic/atomic structure can bring to bear unique physicochemical properties and has been widely applied in the fields of photocatalysis, adsorbents, sensors and chemical templates. However, a comprehensive summary on mpg-C3N4 micro/nanostructures is less reported and there is an urgent need to further promote the development of function-oriented mpg-C3N4-based materials. Herein, we will overview the significant advances in functional mpg-C3N4 polymers, including general synthesis strategies and growth mechanisms, modifications of electronic/atomic structures and interfacial properties (such as exfoliation, doping and hybridizing), as well as their current applications. Finally, several emerging issues and perspectives are also proposed.
