摘要：In this study, we employed an in-situ transformation method to prepared a mesoporous spindle like BiVO4/nanosheet BiOCl composite photocatalyst. The nanostructure and content of 2-D BiOCl could be facilely tuned by controlling the concentration of Cl−ions in the reaction solution. The as-prepared BiVO4-BiOCl photocatalyst showed an excellent photocatalytic norfloxacin degradation performance, and removed it in 1 h almost completely. Further research results indicated that a well-defined p-n heterojunction interface has been formed between BiVO4and BiOCl, to enhance the separation efficiency of photogenerated carriers. In addition, after the nanosheets BiOCl interlaced with the mesoporous BiVO4spindles, since the 2-D structure of the former, the charge transfer capacity of the composite would be improved to prolong the lifetime of the photoinduced carriers.
