| description | Noble metal-free cocatalysts have drawn great interest in accelerating the catalytic reactions of metal chalcogenide semiconductor photocatalyst. In particular, great efforts have been made on modifying a semiconductor with dual cocatalysts, which show synergistic effect of a fast transfer of exciton and energy simultaneously. Herein, we report the dual-modified Cu<sub>2</sub>S with MoS<sub>2</sub> and reduced graphene oxides (Cu<sub>2</sub>S-MoS<sub>2</sub>/rGO). The in situ growth of Cu<sub>2</sub>S nanoparticles in the presence of MoS<sub>2</sub>/rGO resulted in high density of nanoscale interfacial contacts among Cu<sub>2</sub>S nanoparticles, MoS<sub>2,</sub> and rGO, which is beneficial for reducing the photogenerated electrons’ and holes’ recombination. The Cu<sub>2</sub>S-MoS<sub>2</sub>/rGO system also demonstrated stable photocatalytic activity for H<sub>2</sub> evolution reaction for the long term. |
