The CdS/Ni 3 S 2 heterojunction is prepared by a two-step hydrothermal method. The structure and crystalline phase are proved by SEM, TEM and XRD. The photocatalytic hydrogen production performance of the CdS/Ni 3 S 2 heterojunction exhibits about ∼24 times enhancement that of pure CdS. It may be ascribed to the CdS with narrow band gap could increase the solar utilization. What’s more, the Ni 3 S 2 with quick photon-generated electrons transferring could improve the separation of photon-generated carriers.
