The H2 production performance of mpg-CN under visible light is significantly improved by growing thin layers of MoS2 on mpg-CN. The 0.5 wt% MoS2/mpg-CN performs better than 0.5 wt% Pt/mpg-CN under identical reaction conditions. The geometric similarity in the layered structures of MoS2 and g-CN, together with the mesoporous structure of mpg-CN facilitates the planar growth of MoS2 over the mpg-CN surface and the formation of the thin, planar MoS2/mpg-CN interface; these characteristics are believed to promote the photoactivity of MoS2/mpg-CN. We found that other layered transition metal dichalcogenides such as WS2 are also efficient promoters for hydrogen production over gCN. Herein we have presented not only an example of a catalyst made of abundant C, N, Mo and S elements for efficient H2 photosynthesis, but also a conceptual advance to rationally design and fabricate a thin, effective interfacial 2D junctions between co-catalysts and semiconductors that have similar layered geometric structures.
