Construction of a novel Zn3In2S6/Bi2MoO6 composite photocatalyst for enhanced photocatalytic tetracycline degradation

A novel Zn3In2S6/Bi2MoO6 composite photocatalyst with different Zn3In2S6 content is designed and prepared via a two-step hydrothermal strategy. The Zn3In2S6/Bi2MoO6 photocatalyst displays an enhanced photocatalytic performance for degradation of tetracycline under visible light irradiation. The optimized Zn3In2S6/Bi2MoO6 sample, namely 15-ZIS/BMO, presents the highest photocatalytic activity, which can be attributed to much more efficient transfer and separation of photoexcited electron-hole pairs and the enhanced adsorption capacity. This work develops a novel Zn3In2S6/Bi2MoO6 composite photocatalyst with high performance for degradation of tetracycline, and it affords a prototype to efficiently utilize solar energy.
