Se-doped graphene-like MoS2/graphene hybrid (Se-GL-MoS2/G) has been synthesized by an ionic liquid assisted hydrothermal method and is also evaluated as an electrochemical catalyst for hydrogen evolution reaction (HER). The results indicate that Se-doped MoS2 nanosheets are characteristic of monolayers with rich exposed active edges and are well dispersed in the highly conductive graphene networks. Consequently, the desirable microstructures endow the Se-GL-MoS2/G hybrid with significantly enhanced catalytic activity for HER compared with the bare MoS2.
