[PMID: 37630333 PMCID: PMC10459574 DOI: 10.3390/molecules28166082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 08/14/2023] [Accepted: 08/14/2023] [Indexed: 08/27/2023] Open
Abstract
In this study, we have successfully constructed Ag3PO4/Ag/g-C3N4 heterojunctions via the hydrothermal method, which displays a wide photo-absorption range. The higher photocurrent intensity of Ag3PO4/Ag/g-C3N4 indicates that the separation efficiency of the photogenerated electron-hole pairs is higher than that of both Ag3PO4 and Ag/g-C3N4 pure substances. It is confirmed that the efficient separation of photogenerated electron-hole pairs is attributed to the heterojunction of the material. Under visible light irradiation, Ag3PO4/Ag/g-C3N4-1.6 can remove MO (~90%) at a higher rate than Ag3PO4 or Ag/g-C3N4. Its degradation rate is 0.04126 min-1, which is 4.23 and 6.53 times that of Ag/g-C3N4 and Ag3PO4, respectively. After five cycles of testing, the Ag3PO4/Ag/g-C3N4 photocatalyst still maintained high photocatalytic activity. The excellent photocatalysis of Ag3PO4/Ag/g-C3N4-1.6 under ultraviolet-visible light is due to the efficient separation of photogenerated carriers brought about by the construction of the Ag3PO4/Ag/g-C3N4 heterostructure. Additionally, Ag3PO4/Ag/g-C3N4 specimens can be easily recycled with high stability. The effects of hydroxyl and superoxide radicals on the degradation process of organic compounds were studied using electron paramagnetic resonance spectroscopy and radical quenching experiments. Therefore, the Ag3PO4/Ag/g-C3N4 composite can be used as an efficient and recyclable UV-vis spectrum-driven photocatalyst for the purification of organic pollutants.

Abstract
The destruction of the ecological environment caused by human activity and modern industrial development is so severe that the water environment has become seriously polluted. Therefore, the exploration of high-efficiency absorbents has become one of the hot topics to solve this issue. Herein, a porous metal-organic framework [Cu(L)]·2.5H2O·0.5DMF (1, DMF = N,N-dimethylformamide) was successfully constructed using a rigid N-heterocyclic 5-(4-(1H,3,4-triazol-1-yl)phenyl)isophthalic acid (H2L) ligand. In particular, its structure includes the classical paddle-wheel-shaped secondary building units and two 1D channels with diameters of 7.2 and 3.2 Å, respectively. Complex 1 shows great sorption performance for methylene blue (MB) with a maximum capacity of 589 mg·g-1. The various influence factors, including the time, dye concentration, adsorbent dosage, and the pH of the solution, are investigated respectively. Also, the adsorption process is more in line with the first-order kinetics and the Langmuir isothermal adsorption model. The strong electrostatic force and intermolecular forces are primarily responsible for the remarkable adsorption ability of MB.

Abstract
A novel solid-state Z-scheme photocatalyst Ag3PO4/CSs/AgBr (carbon spheres, CSs) was rationally designed and successfully synthesized via a facile hydrothermal coprecipitation reaction. AgBr and Ag3PO4 were effectively loaded on the surface of the CSs and Ag3PO4/CSs/AgBr showed wide visible light absorption and superior photocatalytic performance. On the basis of ultraviolet photoelectron spectroscopy (UPS) analysis and scavenger reactions, a possible photocatalytic reaction mechanism for Ag3PO4/CSs/AgBr is proposed. The CSs act as a charge carrier transfer bridge for constructing the all-solid-state Z-scheme photocatalyst. The photogenerated electrons from Ag3PO4 and holes from AgBr congregate and recombine in the CSs phase, leaving photogenerated electrons with strong reduction abilities in the conduction band (CB) of AgBr and holes with strong oxidation abilities in the valence band (VB) of Ag3PO4. Some Ag+ ions accept electrons and turn to Ag nanoparticles (NPs), leading to the surface plasmon resonance of Ag NPs on AgBr. Therefore, the photocatalytic performance and stability were significantly improved.

Abstract
In this study, an AgBr/Ag3PO4 (ABAP) photocatalyst has been prepared via a facile one-pot anion-exchange method. SEM, XRD, XPS and UV-Vis DRS characterization techniques are carried out to study the structural and physicochemical characteristics of the AgBr/Ag3PO4 composites. The ABAP photocatalyst exhibited outstanding photocatalytic capability for the photodegradation of rhodamine B (RhB) under visible light irradiation. The optimal ABAP-48% composite displayed the highest photocatalytic activity; a complete degradation was attained in 25 min under visible light irradiation. The excellent stability and reusability of ABAP catalysts were examined by five subsequent runs. A probable degradation mechanism of ABAP composites was carefully surveyed. Furthermore, radical trapping experiments confirmed that the ˙O2− radical was the main active species in the photodegradation reaction. In this study, an AgBr/Ag3PO4 (ABAP) photocatalyst has been prepared via a facile one-pot anion-exchange method.![]()

Abstract
In this study, Fe2O3 (hematite) nanoparticles with different crystallite sizes (40-59 nm) were synthesized from Egyptian insecticide cans using the combustion method. The organic fuels were urea, glycine, L-alanine, and L-valine. Fe2O3 nanoparticles were characterized utilizing different devices such as BET, PL, FT-IR, XRD, HR-TEM, FE-SEM, UV-Vis, and DTG. Crystal violet (CV) and methylene blue (MB) dyes were efficiently removed from aqueous solution by photocatalytic degradation under UV irradiation in the presence of Fe2O3 and H2O2. The % degradation of 50 mL crystal violet or methylene blue dye (20 mg/L) using 0.1 g Fe2O3 in the presence of H2O2 was 100% after 30 or 40 min, respectively. Also, the degradation processes are fitted well with the first order model. Besides, the photocatalytic activity of Fe2O3 unaltered even after it was reused three times. Hence, the synthesized Fe2O3 nanoparticles can be considered a promising and efficient photocatalyst for the degradation of crystal violet and methylene blue dyes.
