Simultaneous hydrogen production with the selective oxidation of benzyl alcohol to benzaldehyde by a noble-metal-free photocatalyst VC/CdS nanowires

Muhammad Tayyab et al.

Summary: In this study, CdS nanowires were combined with vanadium carbide using a specific method, and it was found that the photocatalytic activity of the CdS nanowires was significantly enhanced when loaded with vanadium carbide, especially for simultaneous production of H2 and selective oxidation of benzyl alcohol into benzaldehyde. Additionally, the vanadium carbide loading also reduced the recombination rate of hydrogen and benzaldehyde. The results of this study demonstrate the importance of this method in achieving commercialization of photocatalytic hydrogen production.

Preparation and application of BiOBr-Bi2S3 heterojunctions for efficient photocatalytic removal of Cr(VI)

Zeqing Long et al.

Summary: In this study, BiOBr-Bi2S3 heterojunctions with high photocatalytic performance for Cr(VI) reduction were successfully prepared, achieving 100% removal of Cr(VI) within 12 minutes. The performance of photo-reduced Cr(VI) by the heterojunctions was significantly higher than that of pure Bi2S3 and BiOBr, suggesting their potential as a novel photocatalytic adsorbent. Additionally, the heterojunctions showed good adsorption efficiency for Cr(III), indicating their bifunctional capability.
