摘　　要：利用化学镀方法制备了NiB_(x)/NF电极材料,探究其在0.1 mol/L KOH水溶液体系电催化氧化4-甲氧基苄胺的性能。结果表明,适当提高电极中B元素掺杂质量分数可显著提高电极催化性能;使用NiB_(0.54)/NF电极电解4-甲氧基苄胺,90 min内基本全部转化为4-甲氧基苯甲腈,产率为98.2%,法拉第效率为99.3%。NiB_(x)/NF electrode materials is prepared through chemical plating method, and its performance is evaluated in electrocatalytic oxidation of 4-methoxbenzylamine in 0.1 mol·L^(-1)KOH aqueous solution.It is verified that the catalytic performance of the materials can be significantly improved by increasing the doping content of B element appropriately.4-Methoxbenzylamine over NiB_(0.54)/NF electrolysis has entirely been converted into 4-methoxy benzonitrile in 90 min, with a yield of 98.2% and a Faraday efficiency of 99.3%.
