CuS/ZnS heterojunction was formed by cation exchange of defective ZnS, and g-C3n4 was loaded by ultrasonic impregnation method. A CuS/ZnS/g-C3n4 nanocomposite with good visible light response was developed. The CuS/ZnS/g-C3n4 nanocomposites were analyzed and tested by various characterization methods to determine the composition of the composites, and to study their morphology and performance. The hydrogen production capacity was tested by PLS series simulated solar xenon lamp light source with 0.25M NaS and 0.35M Na2SO4 as sacrificial agents. The results show that the prepared CuS/ZnS/g-C3n4 nanocomposites have good activity relative to the defect zinc sulfide and CuS/ZnS. The hydrogen production effect of g-C3n4 containing 5wt% under visible light is 2265.87umol/g.h, which has good visible light responsiveness. The excellent performance of this material is mainly due to its enhanced visible light absorption capacity and difficult recombination of electrons and holes.
