摘要：

By hydrothermal process, a stable electrochemical catalyst for hydrogen evolution reaction (HER) was synthesized based on the nickel doping into molybdenum disulfide nanoparticles supported by reduced graphene oxide (rGO). This ternary composite (Ni-MoS2@rGO) displays a remarkable performance in electrocatalytic HER (506 mV overpotential at a current density of 10 mA.cm(-2)), which is quite better than a lot of graphenes or MoS2 related catalysts as described in numerous articles. Besides this, our catalyst discloses promising kinetics (Tafel slope of 62.7 mV.dec(-1)), robust durability (rarely reduce HER activity during a 12-hour test), more electrochemical active sites, higher turnover frequency over each active sites, and better conductivity, ensuring a perfect HER catalyst for industrial applications.
