BiVO4 prepared by the sol-gel doped on graphite felt cathode for ciprofloxacin degradation and mechanism in solar-photo-electro-Fenton

Weikang Lai et al.

Summary: In this study, GF-BiVO4 was successfully prepared by sol-gel method, exhibiting superior electro-Fenton and solar-photo-electro-Fenton performance. The doping of BiVO4 endowed GF with a higher surface area and more electro-active sites, leading to enhanced electrode activity. GFs were used as cathodes to detect center dot OH concentration and evaluate photoelectric performance in photocatalysis, EF, and SPEF processes, showing promising results for the degradation of CIP.

In-situ prepared MIL-53(Fe)/BiOI photocatalyst for efficient degradation of tetracycline under visible-light driven photo-Fenton system: Investigation of performance and mechanism

Yuhan Ma et al.

Summary: In this study, MIL-53(Fe)/BiOI composites were synthesized and used as photocatalysts in the photo-Fenton system for tetracycline degradation. The enhanced photocatalytic activity was attributed to the efficient separation of electrons and holes, and the main reactive species in the degradation process were identified as h(+) and singlet oxygen. The possible photo-Fenton degradation mechanism was elucidated based on the band structures of MIL-53(Fe) and BiOI, showing promising applications in environmental restoration and protection.

Functional role of mixed-culture microbe in photocatalysis coupled with biodegradation: Total organic carbon removal of ciprofloxacin

Yidi Li et al.

Summary: The combination of photocatalytic-biodegradation using polyurethane sponges modified with visible light-responsive g-C3N4 and mixed culture microbes resulted in 94% removal of ciprofloxacin. This method had a higher total organic carbon (TOC) removal rate compared to photocatalytic degradation alone. The microbial community primarily belonged to Proteobacteria, playing a major role in the efficient degradation process.

Performance improvement of MXene-based perovskite solar cells upon property transition from metallic to semiconductive by oxidation of Ti3C2Tx in air

Lin Yang et al.

Summary: By oxidizing Ti3C2Tx, its properties can be adjusted for use as an electron transport layer in low-temperature processed perovskite solar cells (PSCs), resulting in improved energy conversion efficiency. Heavy oxidation of Ti3C2Tx reduces macroscopic defects in the film and transitions it from a metallic material to a semiconductor, leading to enhanced electron mobility and reduced electron-hole recombination for higher power conversion efficiency (PCE).
