Although Bi7O9I3 is an oxygen-rich bismuth oxyiodide with higher photocatalytic activity than BiOI,its applicability for photocatalytic oxidation is limited by the rapid recombination of photogenerated carriers and poor reusability.Depositing Bi7O9l3 on flexible macro-sized carbonaceous materials is a promising approach for promoting photogenerated electron migration and improving reusability.In this study,a composite consisting of Bi7O9I3 supported on graphitic carbon paper(Bi7O9l3-CP)was synthesized via the in situ transformation of a BiOl-deposited carbon paper precursor(BiOl-CP).The as-prepared Bi7O9I3-CP exhibited higher visible-light-driven photocatalytic activity than both Bi7O9I3 and BiOI-CP precursor for phenol removal.The improved photocatalytic activity of Bi7O9I3-CP was attributed to its hierarchical structure and promoted carrier separation,as revealed by photoluminescence,pore structure,and reactive radical analyses.Moreover,owing to its macroscale size and flexibility,the Bi7O9I3-CP composite could be easily operated and reused,which are favorable for practical applications.
