摘要：Ciprofloxacin hydrochloride (CIP) is a broad?spectrum antibiotic and widely used for urinary and reproductive infections caused by sensitive bacteria. This work reports the photocatalytic decomposition of CIP over Ce?BiOCl nanosheets. Ce?doped BiOCl nanosheets were synthesized by a hydrolysis method with iodine-assisted redox process at room temperature. The structure, morphology, optical absorption and the electrochemical property of the products have been characterized. The results reveal that the doped Ce substantially enhanced the intrinsic photocatalytic performance of BiOCl by forming a doping energy level. The appropriate photocatalytic mechanism was also discussed for the improved photocatalytic performance. Furthermore, the bacteriostatic activity was also tested against E. coli and salmonella. It is interesting that bacteriostatic performance decreased sharply after the photocatalytic degradation of drug solutions with the photocatalyst presence.
