Synthesis of Ru Cs/Mo2C Nanorods and Its Electrocatalytic Hydrogen Evolution

Abstract

Abstract: Mo₂C is known as the most promising electrocatalytic hydrogen evolution catalyst, but its high overpotential and low efficiency restrict its large-scale production. In this paper, Ru nanoclusters (Ru Cs/Mo₂C) supported Mo₂C nanorod composites were prepared by a simple solvothermal method. The results show that Ru Cs/Mo₂C (Ru, mass fraction 7.79%) exhibits superior electrocatalytic hydrogen evolution performance, with a current density of 104 mV at the overpotential of 10 mA·cm^-2, and a Tafel slope of 96.30 mV·dec^-1. Meanwhile, Ru Cs/Mo₂C catalyst has excellent stability and broad application prospects in industrial electrolysis systems.

Key words: Mo₂C, Ru, electrocatalyst, electrocatalytic hydrogen evolution reaction
