摘要: Mo2C被誉为最有前景的电催化产氢催化剂,然而其高的过电压和低效率限制了其规模化生产。本文通过简单的溶剂热法制备了Ru纳米簇(Ru Cs/Mo2C)负载Mo2C纳米棒复合材料。研究表明,Ru Cs/Mo2C(Ru,质量分数7.79%)表现出优异的电催化产氢性能,电流密度在10 mA·cm-2的过电势为104 mV,Tafel斜率为96.30 mV·dec-1。同时,Ru Cs/Mo2C催化剂具有优异的稳定性,在工业电解系统中具有广阔的应用前景。

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
