▎ 摘  要

An ultra-thin MoS2/reduced graphene oxide (UT-MoS2/rGO) catalyst was prepared by one-step hydrothermal method, in which H3PO4 center dot 12MoO(3) and C3H7NO2S were used as precursors and rGO was used as the carbon source. The microstructure of the UT-MoS2/rGO catalyst and its catalytic performance for hydrogen evolution reaction (HER) were studied. The results showed that UT-MoS2/rGO hybrid exhibited excellent electrocatalytic properties due to rich active sites from UT-MoS2, robust support of electrically conducting rGO and good bonding between UT-MoS2 and rGO. The initial overpotential was -66 mV; the overpotential was -145 mV at a current density of -10 mA.cm(-2) with the Tafel slope of 42.9 mV.dec(-1); the AC impedance was 0.76 Omega; the catalytic activity maintained 98% after 1 000 cycles at 0.1 to 0.2 V.d
