摘　　要：开发高效、廉价、稳定的电催化材料,对绿色制氢有着重要意义。以铜片为基体,在氯化胆碱-乙二醇深共熔体系利用电沉积技术制备Ni-Mo-Yb自支撑电极。同时对电极的结构和形貌进行表征,并对其电化学析氢性能进行研究。结果表明稀土镱(Yb)的加入,使镀层表面形成大小均匀的球形颗粒,且在不同沉积电位下,样品具有不同的形貌。在-1.08 V沉积的Ni-Mo-Yb/Cu具有最好的电催化活性和稳定性,电流密度为10 mA·cm^(-2)时过电位仅有48 mV,电荷转移电阻仅为0.2996Ω·cm^(-2)。且在1000次循环伏安后,过电位基本无变化,碱性条件下100 h均能保持稳定。这些优异的电催化析氢性能表明,该材料在绿色工业制氢中极具发展潜力。The development of efficient,cheap and stable electrocatalytic materials is of great significance for green hydrogen production.The Ni-Mo-Yb alloy coatings were electrodeposited in the choline-ethylene glycol deep eutectic system using Cu as the substrates.Meanwhile,the structure and morphology of the electrode were characterized,and the electrochemical hydrogen evolution performance was studied.The results showed that the doping of rare earth Yb made the surface of the coating form spherical particles with uniform size,and the samples have different morphologies under different deposition potentials.Ni-Mo-Yb/Cu excellent electrocatalytic activity and stability.When the current density was 10 mA/cm^(2),the overpotential was only 48 mV,and the charge transfer resistances was only 0.2996Ω/cm^(2).After 1000 cycles of voltammetry,the overpotential basically did not change,and remained stable under alkaline conditions for 100 h.These excellent electrocatalytic hydrogen evolution properties indicated that the material had great development potential in green industrial hydrogen production.
