Solar-driven water splitting via the hydrogen evolution reaction is considered a promising method to resolve global energy and environmental problems in the future. Semiconductor materials have drawn considerable interest in this field; the results are still far from practical applications. Recently, a stable organic photocatalyst, layered graphitic carbon nitride (g-C3N4), was reported to show sufficient visible-light photocatalytic hydrogen generation. However, pristine g-C3N4 suffers from the fast recombination of photo-generated electron-hole pairs. Integration of a co-catalyst helps in promoting the charge separation and then improves the H2 evolution activity. In this work, MoS2 nanosheets are grown on the surface of g-C3N4 nanosheets and the effect of MoS2 on the H2 evolution activity of g-C3N4 was studied. |
