Jingzhen Wang et al.

Summary: In this study, hollow microsphere structures of Bi doped BiOI1-xFx solid solutions were prepared, which effectively reduced the band gap and increased the surface area and active sites for reaction. The Bi/BiOI0.8F0.2 composite exhibited the best photocatalytic performance for decomposing PFOA, with a degradation rate constant tenfold higher compared to pure BiOI and BiOF.

A new synthesizing method of TiO2 with montmorillonite: Effective photoelectron transfer to degrade Rhodamine B

E. Tao et al.

Summary: In this study, a novel photocatalyst material, TMC, was synthesized by loading TiO2 on the surface of MMT to remove Rhodamine B via photocatalytic degradation. The negative potential on the surface of MMT played a crucial role in distributing TiO2 and limiting particle size. Experimental results confirmed that O-center dot(2)- and (OH)-O-center dot were dominant free radicals involved in the photocatalytic process.

Asma El Golli et al.

Summary: Green-synthesized Zinc Oxide nanostructures showed favorable photocatalytic activity in degrading methylene blue dye under concentrated sunlight compared to chemically prepared ZnO. Immobilized photocatalysts, including green-synthesized ZnO nanorods and pulsed laser deposition ZnO thin film, demonstrated the feasibility of the approach in wastewater treatment. An economic analysis indicated that the combination of green synthesis and concentrated sunlight significantly reduces costs for large-scale photocatalytic wastewater remediation.

Self-assembled ultrathin CoO/Bi quantum dots/defective Bi2MoO6 hollow Z-scheme heterojunction for visible light-driven degradation of diazinon in water matrix: Intermediate toxicity and photocatalytic mechanism

Xiaoming Xu et al.

Summary: The ultrathin CoO/Bi quantum dots (QDs)/Bi2MoO6 with oxygen vacancies (OVs) hollow Z-scheme heterojunction exhibited excellent photocatalytic activity in diazinon degradation, achieving a removal efficiency of 94.2%. The study also investigated the effects of catalyst dosage, pH, different anions, and humic acid on diazinon removal, confirming the eventual conversion of diazinon into harmless products based on toxicity assessment. The improved photocatalytic activity was attributed to the synergistic effect of various factors, such as ultrathin hollow structure, surface plasmon resonance (SPR) effect, OVs, and the Z-scheme heterostructure, leading to enhanced visible light absorption and fast charge separation.

Photocatalytic degradation of ibuprofen on S-doped BiOBr

Yang Liu et al.

Summary: Doping S into the lattice of BiOBr to synthesize S-BiOBr significantly enhances the degradation efficiency and kinetic constant for the visible-light-driven degradation of ibuprofen. This is attributed to the band structure tuning by S-doping, leading to higher visible light utilization efficiency. OH radicals play a synergistic role with holes in the degradation process on S-BiOBr, which is more efficient than the reported single hole- or superoxide-dominant reactions.

Facile construction of 2D g-C3N4 supported nanoflower-like NaBiO3 with direct Z-scheme heterojunctions and insight into its photocatalytic degradation of tetracycline

Yixiao Wu et al.

Summary: The composite photocatalyst g-C3N4/NaBiO3 showed superior performance in degrading tetracycline compared to individual g-C3N4 or NaBiO3, attributed to the accumulation of photoinduced electrons on g-C3N4 and holes on NaBiO3 for efficient generation of superoxide and hydroxyl radicals. The built-in electric field between g-C3N4 and NaBiO3 enhanced charge separation, leading to stable photodegradation activity for multiple cycles. This work not only provides a promising photocatalyst for antibiotic contaminants, but also sheds light on the photocatalytic removal of tetracycline.
