摘要：
A novel three-dimensional(3D)layered MoS2@graphene functionalized with nitrogen-doped graphene quantum dots(MoS2@N-GQDs-GR)composites as an enhanced electrochemical hydrogen evolution catalyst.The few layered MoS2nano flowers supported on N-GQDs-GR surface were elaborately fabricated by one-pot hydrothermal method,which MoS2and N-GQDs-GR exist in a bonding manner of Mo-N.In addition,due to the layered MoS2sheet edge exposes more hydrogen evolution active sites and N-GQD s-GR have high conductivity,the composites exhibit prominent electrocatalytic activity with a low ove rpotential 99 mV,a small Tafel slope 49.3 mV/dec.Therefore,that the curre nt work will develop HER catalysts may replace Pt.
