A photocatalytic material with high performance and low cost plays a decisive role in the industrialization of photocatalytichydrogen evolution. In this work, Cu3BiS3 nanoparticles were successfully synthesized by the microwave irradiationmethod, and the formation mechanism of Cu3BiS3 was studied. The Cu3BiS3 was a nanorod structure with 122 nm diameterand 41 nm length. The band gap was 1.31 eV and the EVB was located at 0.15 eV from the Mott-Schottky analysis. The Cu3BiS3 electrode exhibited an excellent HER performance with an onset potential of 870 mV, a Tafel slope of 251.07mV/dec. And the charge transfer resistance (Rct) of Cu3BiS3 electrode was 7.2 Ω. The electrode also revealed the goodphotoelectric response ability. The electrode also revealed the good photoelectric response ability and good stability bytime course of the photocurrents. This work provided a fast, low-cost method to prepare the Cu3BiS3 for photocatalysiswater splitting.
