摘要
Mo_(2)C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/Mo_(2)C)负载Mo_(2)C纳米棒复合材料。研究表明,Ru Cs/Mo_(2)C(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/Mo_(2)C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。
Mo_(2)C 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/Mo_(2)C)supported Mo_(2)C nanorod composites were prepared by a simple solvothermal method.The results show that Ru Cs/Mo_(2)C(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/Mo_(2)C catalyst has excellent stability and broad application prospects in industrial electrolysis systems.
