Summary: Fe-MOF derivative (M-300) was prepared by thermal treatment using MIL-100(Fe) as a precursor. M-300 catalyst showed excellent performance in the degradation of volatile organic compounds (VOCs) and bacteriostasis to Escherichia coli under visible light. The catalyst also exhibited the capacity of acetaldehyde degradation under actual sunlight. The high activity of M-300 is attributed to the abundant exposure of the unsaturated Fe2+ active site, promoting electron transfer and oxygen reduction process, thereby improving the efficiency of the photocatalytic oxidation reaction. This study demonstrates the potential application of MOFs derivatives in indoor photocatalytic purification and provides a new insight into catalyst modification for photocatalytic degradation of pollutants.

Summary: The role of excitons and hot carriers in photo-induced processes, as well as their benefits in charge transfer in photocatalysis, were explored using an AgI/Bi3O4Br model. The reduction of spin-orbit coupling and presence of oxygen vacancies in the heterojunction were identified as key factors contributing to the high efficiency of ROS generation. The interfacial interaction between AgI and Bi3O4Br also played a significant role in reducing the generation of O-1(2) and increasing the production of O-2 center dot(-) and center dot OH center dot radicals, leading to effective degradation of organic pollutants in wastewater.

Summary: In this study, TiO2/SiO2 photocatalysts were prepared and the calcination temperature of 800 degrees C resulted in the highest photocatalytic activity for phenanthrene degradation. The composite material showed minimal phenanthrene uptake but strong photocatalytic activity, with the formation of Ti3+ under solar light irradiation promoting photoexcited electron trap and separation of electron-hole pairs. High electrophilic Fukui index atoms of phenanthrene were identified as the most reactive sites towards radicals during the degradation process.

Summary: This study developed a self-modification strategy to prepare carbon-deficient and oxygen-doped g-C3N4 catalyst, which showed high efficiency in photocatalytic removal of p-nitrophenol and atrazine. The mechanism behind this efficiency is the synergistic effect of carbon vacancies and oxygen doping sites in generating abundant active oxygen species.

Summary: This study investigated three typical photoelectrodes for PEC-RCS systems and found that BiVO4 demonstrated superior performance in inhibiting the formation of harmful oxychlorides compared to TiO2 and WO3. By utilizing valence band dependent photoelectrochemical properties, BiVO4 could effectively restrict the production of ClO3- and ClO4-, making it a promising candidate for PEC-RCS applications.

Summary: In this study, a Cl-doped g-C3N4 nanotube composite Ti3C2 (Cl-TCN@TC) photocatalyst was prepared for the first time, which has significant advantages in decarbonization and denitrification of wastewater. The Cl-TCN@TC-2 showed excellent removal effects on tetracycline (TC, 91.08%) and p-nitrophenol (p-NP, 70.92%). The kinetic constants for the degradation of TC and p-NP by Cl-TCN@TC-2 were significantly higher than those of CN. The COD removal rates of domestic sewage and oilfield produced water by Cl-TCN@TC-2 reached 54.2% and 64.8%, respectively. After the addition of HCOOH, the denitrification rate of Cl-TCN@TC-2 reached 50.24%, which was 12.62 times higher than that of CN, with a N2 selectivity of 92.46%.

Summary: This study established a coupling system by integrating sulfate radical-based advanced oxidation processes (AOPs) with photocatalysis to enhance the activation of peroxymonosulfate (PMS) under visible light. The researchers developed a novel catalyst, 5%Bi3O4Br/CuBi2O4, for the rapid and efficient degradation of tetracycline (TC). The degradation rate constant in the 5%Bi3O4Br/CuBi2O4 + PMS + Vis system was significantly higher than that of photocatalysis and (SO4-)-S-center dot-AOPs alone. The study provides insights into the degradation pathways of TC and demonstrates the potential of this environmentally-friendly system for the efficient degradation of antibiotics.
