Dual-Modified Cu2S with MoS2 and Reduced Graphene Oxides as Efficient Photocatalysts for H2 Evolution Reaction

Noble metal-free cocatalysts have drawn great interest in accelerating the catalytic reactions of metal chalcogenide semiconductor photocatalyst. In particular, efforts been made on modifying a with dual cocatalysts, which show synergistic effect fast transfer exciton and energy simultaneously. Herein, we report dual-modified Cu2S MoS2 reduced graphene oxides (Cu2S-MoS2/rGO). The situ growth nanoparticles presence MoS2/rGO resulted high density nanoscale interfacial contacts among nanoparticles, MoS2, rGO, is beneficial for reducing photogenerated electrons’ holes’ recombination. Cu2S-MoS2/rGO system also demonstrated stable photocatalytic activity H2 evolution reaction long term.
