Summary: In this study, different amounts of polypyrrole modified BiVO4 photocatalyst were synthesized, and the optimal doping amount of 5% showed the highest photocatalytic activity. The mechanism of enhanced activity was discussed, with photogenerated holes transferring to the pi orbital of PPy and electrons transferring to the conduction band of BiVO4 for effective charge separation and stabilization.

Summary: Bi0/BiVO4 was synthesized using ascorbic acid, and its microstructure, morphology, optical properties and photogenerated carriers separation behavior were investigated. The photocatalytic degradation of RhB by Bi0/BiVO4 under visible light irradiation was studied, showing that the photocatalytic performance of Bi0/BiVO4 is significantly improved compared to BiVO4. This enhancement is mainly attributed to the surface plasmon resonance effect of Bi0 deposited on the surface of BiVO4, which expands the light response range and accelerates the separation of photogenerated carriers. This study provides valuable insights for the preparation of excellent catalysts.

Summary: A photocatalytic coupling persulfate system was constructed for efficient degradation of Iohexol using a novel binary photocatalyst PB. The active species were identified as holes and hydroxyl radicals, with free radical chain reactions and mutual conversion reactions occurring during the degradation process. Metal-free supramolecular loaded photocatalysts show potential for application in the removal of organic pollutants for water remediation.

Summary: In this study, a stable material, BiBDC/BiVO4 heterojunction, was constructed by using a hydrothermal method to efficiently remove organic pollutants from water under visible light irradiation. The improved performance is attributed to the broadened optical absorption range and accelerated separation of photogenerated electrons and holes by the heterojunction. BiBDC/BiVO4 also showed excellent reusability and stability, making it a potential candidate for practical application.

Summary: In this study, BN-BiVO4 composites with visible-light response were prepared and used for the degradation of TCs. Results showed that 4BN-BiVO4 displayed superior photocatalytic performance under visible light irradiation, with 3.6 and 2.3 times higher degradation efficiency for TC and OTC compared to BiVO4. The combination of BN and BiVO4 effectively promoted the separation of photogenerated electrons and holes, enhancing the photocatalytic activity. The dominant reactive species were found to be center dot OH radicals and holes. Based on the experiments and characterization analysis, a possible photocatalytic mechanism for TCs degradation was proposed.

Summary: A novel large-scale recyclable cotton fabric-based rGO/BiVO4 photocatalytic nanocomposites were fabricated for dye degradation under visible light, showing high degradation efficiency and stability. The mechanism of improved photocatalytic properties of the nanocomposites was revealed through analysis of photocurrent response, electrochemical impedance spectroscopy, and electron spin resonance. This kind of fabric-based photocatalytic nanocomposites are expected to have broad applications in wastewater treatment.

Summary: Heterostructure BiVO4/Bi2O3 nanocomposites with enhanced visible light activity were synthesized through a hydrothermal route. The p-n heterojunction formed between the p-type Bi2O3 and n-type BiVO4 effectively reduced the recombination of photogenerated charge carriers, leading to excellent photocatalytic performance and stability.

Summary: The study successfully synthesized a snow-like BiVO4 with rich oxygen vacancy by adjusting the surfactant, which significantly improved the separation efficiency of photo-generated carriers, and subsequently enhanced the photodegradation of CIP. The main active species contributing to CIP degradation were identified as photogenerated holes and center dot O2-, and a proposed transformation pathway for CIP was established based on the identified products.

Summary: This study synthesized a series of composite cuprous oxide and bismuth vanadate photocatalysts using a chemical method, and investigated their photocatalytic activity in degrading antibiotics. The results showed that the 5% Cu2O/BiVO4 composite exhibited the highest photocatalytic activity. Furthermore, the composite demonstrated stability and reusability, and its improved performance was attributed to decreased electron-hole recombination rate and increased surface area.
