Summary: This study aimed to investigate the photocatalytic degradation of 4-chlorophenol using NiO/F-TiO2 composites. F-TiO2 support was prepared by fluorination of TiO2 using the sol-gel method. Heterostructured materials were prepared with varying NiO content. The characterization studies revealed that TiO2 coupled with fluoride ions promoted the generation of Ti-F surface species, leading to improved photoactivity and higher degradation percentages of the phenolic contaminant. The optimum photocatalytic treatment was observed with 1.0% wt of NiO content.

Summary: This study investigated the microbial and biodegradation kinetics of acclimated-mixed sludge to 4-chlorophenol in an aerobic sequencing batch reactor. The biodegradation kinetics were predicted accurately using the Haldane formulae. However, pure strains isolated from mixed sludge did not show higher 4-CP-removal efficiency due to the presence of an intermediate meta-cleavage product.

Summary: A metal-free organic photocatalyst, dBIP-OMe, was reported for the photocatalytic trifluoromethylation of alkenes without the use of sacrificial reagents. Mechanistic studies revealed two consecutive single-electron-transfer reactions between dBIP-OMe, CF3 precursor, and the alkene substrate. The trifluoromethylative bifunctionalization strategy using dBIP-OMe was applicable for both aryl and aliphatic alkenes, and various nucleophiles could be easily incorporated into the carbocation intermediate, broadening the application scope of this photocatalytic method.

Summary: The photocatalytic degradation of 4-chlorophenol (4-CP) was successfully achieved under natural sunlight using zinc oxide nanorods (ZnO NRs) and gold nanoparticles (AuNPs) decorated ZnO NRs catalysts. The degradation efficiency reached 97% within 180 min for 10 ppm of 4-CP with 0.1 mM AuNPs concentration. The enhanced absorption in the visible region and visible-light-induced localized surface plasmon resonance property of AuNPs played a crucial role in promoting the electrons and holes separation and reducing recombination. The ZnO-Au catalyst exhibited great potential for environmental decontamination of organic pollutants.

Summary: The study aimed to enhance the efficient photocatalytic degradation of chlorophenols by addressing the issues of poor utilization of visible light and easy recombination of photogenerated electrons and holes. By forming a g-C3N4/PTCDI-Br heterojunction, the visible-light absorption and interfacial charge transfer were improved, leading to enhanced photocatalytic activity and stability during the degradation of 4-chlorophenol under UV-vis light irradiation. This finding provides new insight into the design strategy for PTCDI-based photocatalysts with excellent performance.

Summary: The degradation of industrial pollutants 4-chlorophenol and 4-bromophenol was studied using TiO2 nanoparticles with different sizes and allotropes for heterogeneous photocatalysis. The photocatalytic activity of a wide range of TiO2 nanoparticles was correlated with their physicochemical properties. The degradation rate of halophenols increased with the size of anatase particles, while it decreased with the size of rutile particles. Different reactive species dominated the degradation of halophenols depending on the size of anatase nanoparticles. Alternative degradation pathways were proposed based on DFT modeling, involving hydroxylation or direct decarboxylation. The antibacterial activity of nanoparticles and degradation intermediates, as well as the changes in toxicity during the photocatalytic process, were also investigated.
