摘　　要：　研究了电沉积制备的非晶态Fe Mo合金(组成分别为Fe82Mo18、Fe74Mo26和Fe71Mo29)电极在30%KOH溶液中,303～343K的温度范围内的析氢催化性能。三种非晶态合金都显示出较好的催化析氢活性。温度为343K,析H2电流密度为300mA/cm2时的析H2过电位为150～157mV。非晶态Fe82Mo18、Fe74Mo26和Fe71Mo29合金上析H2反应的表观活化能分别为57.18,47.33,102.28kJ/mol。The cathodic hydrogen evolution reactions of three electrodes, which respectively electrodeposited amorphous Fe\|Mo alloys Fe82Mo18, Fe74Mo26 and Fe71Mo29, were studied in a 30% KOH solution between temperatures from 303 K to 343 K. All of the electrodes showed higher electrocatalytic activities in the alkaline solution. The hydrogen evolution overpotential of three alloys were 150～157 mV at 343 K and current density of 300 mA/cm\+2. The apparent activation energies of hydrogen evolution reaction were 57.18 kJ/mol for Fe82Mo18, 47.3 kJ/mol for Fe74Mo26 and 102.28 kJ/mol for Fe71Mo29, respectively.
