Abstract: NiS2 nanoparticles as noble metal-free co-catalyst were deposited onto the CdLa2S4 photocatalyst through a hydrothermal process. The loading of NiS2 co-catalyst resulted in remarkable enhancement for H2 production over the CdLa2S4 photocatalyst under visible light irradiation. The optimal hybrid photocatalyst with 2 wt% NiS2 loading exhibited a H2 production rate of 2.5 mmolh-1g-1, which was more than 3 times higher than that of pristine CdLa2S4 photocatalyst. The promoted photocatalytic H2 production by NiS2 co-catalyst loading is attributed to the enhanced separation of photogenerated electrons and holes as well as the activation effect of NiS2 for H2 evolution.
