Yang L, Li H, Jin X, Chen Z. The origins of potentially superior properties and multifunctionalities of carbon-nano zero-valent iron in the carbonization pyrolysis process. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 344:118457. [PMID: 37352626 DOI: 10.1016/j.jenvman.2023.118457] [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: 03/29/2023] [Revised: 05/24/2023] [Accepted: 06/16/2023] [Indexed: 06/25/2023]
Abstract
Although carbon-nano zero-valent iron (C@nZVI) composites with unique properties have been used for environmental remediation, the origins of their superior properties and multifunctionalities of C@nZVI still need to be verified. Here, iron precursor nanoparticles (PML-Fe NPs) synthesized by Pinus massoniana Lamb and carbonized C@nZVI were systemically compared to reveal the origins of the structure and performance of C@nZVI composites. Characterizations showed that structure-modulated C@nZVI has favorable properties of good crystallinity, graphite carbon-rich structure but also defects when compared to PML-Fe NPs. The resultant carbon layer fundamentally improved its dispersion and anti-oxidation properties. Further experiments demonstrated that the evolution of material crystallinity, graphitization and defects affected the reaction pathway of hexavalent chromium (Cr(VI)), oxytetracycline hydrochloride (OTC), and 17β-estradiol (βE2). The multifunctionalities covered adsorption, reduction and catalytic oxidation. This study explains the origins of multifunctional C@nZVI by understanding the structure-property correlation in the carbonization process.

Abstract
The facile and low-cost fabrication of free-standing magnetic catalysts with high catalytic efficiency, rapid reaction rate and excellent recoverability has been pursued for various catalysis applications, e.g., treating aqueous organic 4-nitrophenol pollutants. Here, we design and fabricate a free-standing nickel-coated hyperporous polymer foam (Ni-HPF) with adjustable shapes and sizes, hierarchical multiscale porous structures, abundant catalytical interfaces and excellent super-paramagnetic properties. Due to the synergistical effect of abundant binding sites and highly catalytic reduction, the as-prepared Ni-HPF has demonstrated high conversion efficiency (> 90% at extremely low concentration of 7.5 μM) and rapid reaction rate (2.58 × 10-3 s-1) for the reduction of organic 4-nitrophenol. Moreover, the magnetic catalyst also holds excellent recoverability (>80% conversion rate even after 1000 cycles) and good reproducibility (>80% conversion rate after 3 months of storage). As such, this work with novel material design and working principle could provide a wide range of potential applications in water purification, chemical catalysis and energy storage devices.

Abstract
Herein, a multifunctional ratiometric fluorescent (RF) probe Fe-MIL-88NH2@RhB was fabricated for individual detection of Cu2+/Glu and continuous sensing of Glu based on unique coordination principle by encapsulating RhB into the porous of metal-organic-framework-Fe-MIL-88NH2. Designed Fe-MIL-88NH2@RhB platform could selectively identify Cu(II)/Glu accompanying a turn-off/turn-on fluorescent behavior with good linearity. Moreover, if the Fe-MIL-88NH2@RhB/Cu2+ is treated with Glu continuously, the quenching fluorescence of this platform (after Cu2+ sensing at blue emission) would be further in turn restored. Utilizing Fe-MIL-88NH2@RhB probe, the imaging of intracellular Cu(II) and Glu in living A549 cells was successful conducted through divisional channels with a satisfactory low cytotoxicity, meanwhile, the sensing results of Glu in serum by the molecular logic gate was also superior, which may use for development of an medical occupational tool for amyotrophic lateral sclerosis tentative diagnosis. In addition, the MOF shows di-modal response (color and lumescence) to Cu2+ and Glu with excellent selectivity against a wide range of other interference analytes, and the corresponding portable low-toxicity on-line test strips for Cu2+ and Glu recognize has exhibited a remarkable visually chromogenic phenomena, which may utilize for monitoring these contaminants in real water sample. Finally, the feasibility of probe to monitor Cu2+ and Glu in foodstuffs was also evaluated.

Abstract
The development of low-cost and efficient electrocatalysts for oxygen evolution reaction (OER) is of great importance for producing hydrogen via water splitting. Metal-organic frameworks (MOFs) provide an opportunity for the facile preparation of high-efficiency OER electrocatalysts. In this work, we prepared iron-doped nickel nanoparticles encapsulated in nitrogen-doped carbon microspheres (Fe-Ni@NC) with a unique hierarchical porous structure by directly pyrolyzing the MOF precursor for effectively boosting OER. The Fe doping has a significant enhancement effect on the catalytic performance. The optimized Fe (5%)-Ni@NC catalyst represents a remarkable activity with an overpotential of 257 mV at 10 mA cm-2 and superior stability toward OER in 1.0 M KOH.

Abstract
Heterogeneous hydrogenation reactions are of great importance for chemical upgrading and synthesis, but still face the challenges of controlling selectivity and long-term stability. To improve the catalytic performance, many hydrogenation reactions utilize special yolk/core-shell nanoreactors (YCSNs) with unique architectures and advantageous properties. This work presents the developmental and technological challenges in the preparation of YCSNs that are potentially useful for hydrogenation reactions, and provides a summary of the properties of these materials. The work also addresses the scientific challenges in applications of these YCSNs in various gas and liquid-phase hydrogenation reactions. The catalyst structures, catalytic performance, structure-performance relationships, reaction mechanisms, and unsolved problems are discussed too. Also, a brief outlook and opportunities for future research in this field are presented. This work on the advancements in YCSNs might inspire the creation of new materials with desired structures for achieving maximal hydrogenation performances.

Abstract
Development of an efficient heterojunction catalyst with a superior visible-light driven activity is regarded as a promising strategy to decontaminate organic wastewater. Herein, a novel direct Z-scheme β-Bi2O3@CoO heterojunction was well designed and successfully fabricated by in situ incorporating the two energy band-matched semiconductors. The obtained β-Bi2O3@CoO hybrid presented a unique 3D hierarchical structure with a mass of open channels and mesoporous, which afforded not only rapid mass transfer of targets but also good light-harvesting in view of the multiple reflections. Compared to the pristine β-Bi2O3 and CoO, the β-Bi2O3@CoO hybrid exhibited remarkably improved photocatalytic activity towards the simultaneous degradation of chlorotetracycline (CTC), tetracycline hydrochloride (TCH), oxytetracycline (OTC) and nitrobenzene (NB) under visible-light irradiation. The possible intermediates and degradation pathways were also tracked by mass spectra (MS) analysis. Moreover, a direct Z-scheme charge transfer mechanism in the intimate contact interface between β-Bi2O3 and CoO was verified for the improved catalytic activity, endowing the effective separation/transportation of the photo-excited charge carriers and maintenance of the strong redox ability in β-Bi2O3@CoO heterojunction. The present work affords a simple approach to design and construct 3D hierarchical direct Z-scheme photocatalysts with promising applications in water environment remediation.

Abstract
Ultrathin nanoplates of metastable 1T-MoS2 have been successfully stabilized and uniformly distributed on the surface of n-butyl triethyl ammonium bromide functionalized polypyrrole/graphene oxide (BTAB/PPy/GO) by a very simple hydrothermal method. BTAB as a typical kind of quaternary ammonium-type ionic liquids (ILs) played a crucial role in the formation of the obtained 1T-MoS2/BTAB/PPy/GO. It was covalently linked with PPy/GO and arranged in a highly ordered order at the solid-liquid interface of PPy/GO and H2O due to Coulombic interactions and other intermolecular interactions, which would induce and stabilize ultrathin 1T-MoS2 nanoplates by morphosynthesis. The good electrocatalytic activity toward nitrogen reduction reaction (NRR) with strong durability and good stability can be achieved by 1T-MoS2/BTAB/PPy/GO due to their excellent inorganic/organic hierarchical lamellar micro-/nanostructures. Especially, after the long-term electrocatalysis for NRR at a negative potential, metastable 1T-MoS2 as the catalytic center undergoes two types of irreversible crystal phase transition, which was converted to 1T'-MoS2 and Mo2N, caused by the competitive hydrogen evolution reaction (HER) process and the electrochemical reaction between the electroactive 1T-MoS2 and N2, respectively. The new N-Mo bonding prevents Mo atoms from binding to other N atoms in N2, resulting in the deactivation of the electrocatalysts to NRR after being used for 18 h. Even so, quaternary ammonium-type ILs would induce the crystal structures of transition-metal dichalcogenides (TMDCs), which might provide a new thought for the reasonable design of electrocatalysts based on TMDCs for electrocatalysis.

Abstract
The excessive accumulation of sulfonamides (SAs) drugs makes it imperative to develop novel materials for boosting simultaneously efficient removal and precise monitoring of multiple SAs. Herein, three-dimensional hollow flower-like Ni@nitrogen-doped graphitic carbon (3DHFNi@NGC) was designed/fabricated via a facile one-pot hydrothermal route and subsequent pyrolysis. The resultant 3DHFNi@NGC exhibits a unique 3D hollow hierarchical architecture assembled by a layer-by-layer interlacing of corrugated nanosheets subunits, thereby affording numerous interconnected channels, available internal/external surfaces as well as suitable interior cavities. By virtue of its special architecture and in-situ generated N-doped graphitic carbon along with good magnetism, the 3DHFNi@NGC demonstrates superior sorption performance towards SAs, accompanied by high total saturated adsorption capacity, fast sorption rate and easy magnetic recycling. It is noteworthy that as-constructed 3DHFNi@NGC also exhibits high-sensitive/simultaneous detection of trace multiple SAs combined high performance liquid chromatography (HPLC), together with a low detection limit (0.035-0.071 ng mL-1) and a broad linear range (0.2-100 ng mL-1) as well as high enrichment factors (252 < EFs < 291). These indicate that the smart 3DHFNi@NGC could be a promising candidate for the synchronous remediation and sensitive detection of multiple SAs in aqueous systems, presenting a viable option for sewage treatment and water quality monitoring.

Abstract
In this work, 3D hierarchical Cu2SnS3@SnS2 flower assembled from nanopetals with sandwich-like Cu2SnS3-SnS2-Cu2SnS3 double interfacial heterojunction was successfully designed and synthesized on fluoride doped tin oxide (FTO) for photoelectrochemical (PEC) sensor by in situ electrodeposition p-type Cu2SnS3 nanoparticles on both inner and outer surfaces of n-type SnS2 nanopetals. The unique double interfacial heterojunction simultaneously combines 3D flower-like architectures to drastically increase the light trapping and absorption in visible-near infrared range (Vis-NIR), and dramatically inhibites the charge carrier recombination, which is crucial for boosting the PEC activity. Benefitting from the shape and compositional merits, the Cu2SnS3@SnS2 heterojunction possess dual-mode signal by controlling the electrodeposition time to manipulate the composition ratio of Cu2SnS3 and SnS2. The Cu2SnS3@SnS2/FTO electrode not only exhibits excellent photoeletro-reduction capacity for ultra-sensitive sensing trace persistent organic pollutant (nitrobenzene, NB), but also presents photoeletro-oxidization activity for high selective detection of L-cysteine (L-Cys) without any auxiliary enzyme under the light illumination. Dual mode sensor displayed superb performance for the detection of NB/L-Cys, showing a wide linear range from 100 pM to 300 μM/10 nM to 100 μM and a low detection limit (3S/N) of 68 pM/8.5 nM, respectively. Such a tunable double interfacial heterojunction design opened up new avenue for constructing multifunction PEC sensing platform.
