Abstract: In recent years, many effective photocatalysts have been developed to solve the problem of environmental pollution and clean energy shortage. In this paper, non-noble metal cocatalyst Ni3N nanoparticles supported Zn0.5Cd0.5S (ZCS) nanorods (Ni3N/ZCS) composites were successfully synthesized by ultrasonic method. The hydrogen production efficiencies of the photocatalysts were tested under visible light, which was found that when the loading of Ni3N was 2% of the mass of ZCS, and the Ni3N/ZCS composite had the best hydrogen evolution performance, which could reach 70.3 mmol·h-1·g-1. In addition, the quantum efficiency under 420 nm monochromatic light irradiation was 27.2%. Through different characterization analyses, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis diffuse reflectance spectra (DRS), a possible photocatalytic mechanism was proposed, providing some reference values for non-precious metals as cocatalysts.
