“…It can be seen from Figure e that the TEMPO signal gradually diminished with prolonged photoirradiation, due to the h + oxidation of TEMPO. This suggests effective production of h + under visible irradiation . In addition, a sextet was observed, as shown in Figure f, due to the DMPO- • O 2 – adduct, and the signals intensified with increasing photoirradiation time, indicative of enhanced • O 2 – formation.…”

Photocatalysis represents an effective technology for environmental remediation. Herein, a series of Zn-doped BiOBr hollow microspheres are synthesized via one-pot solvothermal treatment of bismuth nitrate and dodecyl ammonium bromide in ethylene glycol along with a calculated amount of zinc acetate. Whereas the materials morphology and crystal structure remain virtually unchanged upon Zndoping, the photocatalytic performance toward the degradation of ciprofloxacin is significantly improved under visible light irradiation. This is due to the formation of a unique band structure that facilitates the separation of photogenerated electron−hole pairs, reduced electrontransfer resistance, and enhanced electron mobility and carrier concentration. The best sample consists of a Zn doping amount of 1%, which leads to a 99.2% degradation rate of ciprofloxacin under visible photoirradiation for 30 min. The resulting photocatalysts also exhibit good stability and reusability, and the degradation intermediates exhibit reduced cytotoxicity compared to ciprofloxacin. These results highlight the unique potential of BiOBr-based photocatalysts for environmental remediation.

With the serious pollution of water resources in the process of social development, green and environmentally friendly photocatalytic technology has gradually attracted widespread attention. Though photocatalytic theory and technology are relatively mature, the current research is mainly focused on powders and less on the photocatalytic membranes, and few real practical cases of photocatalysis are studied. To summarize and update these advanced studies, this paper introduces the latest progress in photocatalytic membranes including discussing the differences of photocatalytic mechanism between free and fixed photocatalytic systems and the design philosophy of photocatalytic membranes. At the same time, some common fabrication methods, including in situ growth, coating, spinning, casting, and foaming methods are analyzed. Besides, the photocatalytic performances of different photocatalytic membranes in the actual environment and their use conditions are explored. Finally, a critical view of future trends is included. The explanation of the photocatalytic mechanism, large‐scale production, and the practicality of photocatalytic products are all problems that need to be solved in the future.
