Herein, Ag/In2S3/ZnO nanorods (NRs) composite photocatalysts were successfully prepared by simple ways. Significantly, hydroxyl radical active substances were found in the electron spin resonance tests of In2S3/ZnO NRs and Ag/In2S3/ZnO NRs, which indicates that the oxidation reaction that oxidizes water or hydroxide ions into hydroxyl radicals occurs on the valence band of ZnO NRs. It suggests that Z-scheme heterojunction was successfully constructed. In the photocatalytic experiments of degrading 4-nitrophenol (PNP) , the Ag/In2S3/ZnO NRs composite exhibits higher photocatalytic activity than ZnO NRs, In2S3, Ag/ZnO NRs and In2S3/ZnO NRs. The characteristic peak of PNP disappears completely in 50 min. The enhanced photocatalytic performance can be attributed to the formation of Z-scheme heterojunction between ZnO NRs and In2S3. In addition, local surface plasmon resonance (LSPR) of Ag and Schottky junction formed between Ag and In2S3 also promote the photocatalytic activity.
