Abstract
Exploiting non-noble metallic cocatalysts for photocatalytic H2 production is of great significance. Here, metallic 1T-rich MoS2 nanoparticles embedded C3N4 hollow spheres were successfully prepared by an in-situ transformation method. The particular embedded hollow sphere structure enhances the interaction between heterojunctions. 1T-rich MoS2 with abundant active sites as a cocatalyst can promote electron transfer, improve the separation and transmission of photogenerated carriers and boost H2 production. CN/MoS2-1 exhibits a considerably improved H2 production rate (441.3 μmol g−1 h−1) and maintains outstanding stability. This work replenishes a prospective thought for the design of novel catalyst-cocatalyst systems for enhancing photocatalytic H2 production.
