摘　　要：采用由10 g/L NiCl_(2)·6H_(2)O、30 g/L NH_(4)Cl和350 g/L Ni(NH_(2)SO_(3))2·4H_(2)O(氨基磺酸镍)组成的镀液(pH=3.8),在温度25~45℃和电流密度3 A/dm^(2)的条件下电镀30 min,获得镍电极。研究了镀液温度对镍镀层表面形貌和析氢催化活性的影响。结果表明,镀液温度为35℃时,镍镀层结晶最细致,电催化析氢性能和稳定性最佳。A nickel electrode was obtained by electroplating nickel on pure copper in a bath(pH=3.8)comprising NiCl_(2)·6H_(2)O 10 g/L,NH_(4)Cl 30 g/L,and Ni(NH_(2)SO_(3))2·4H_(2)O(nickel sulfamate)350 g/L at temperature 25-45℃ and current density 3 A/dm2 for 30 min.The effect of bath temperature on the surface morphology of nickel coating and its catalytic activity for hydrogen evolution reaction was studied.The results showed that the nickel coating electroplated at temperature 35℃ was the finest and most compact with the best electrocatalytic activity and stability in hydrogen evolution reaction.
