摘要
用循环伏安、交流阻抗测试,研究了添加剂三乙烯四胺、三聚氰胺对金(Au)催化硼氢化钠(NaBH4)直接氧化的影响。三乙烯四胺和三聚氰胺的吸附作用可减少电极表面的BH4-,使每个BH4-有更多的H原子能接触到催化点发生氧化。三乙烯四胺和三聚氰胺改善NaBH4在Au催化下直接氧化的最佳浓度分别为160μmol/L、1.6μmol/L。
Effects of additives triethylene tetramine and melamine on the direct oxidation of sodium borohydride with aurum（Au） catalyst were studied by cyclic vohammetry and electrochemical impedance spectroscopy tests . More H atoms of each BH4 - could oxidate at the catalytic spots due to the absorption of triethylene tetramine and melamine which reduced BH4 - on electrode. The catalytic action of Au on direct oxidation of sodium borohydride was improved through adding triethylene tetramine and melamine, the optimal concentration were 160 umol/L and 1.6 umol/L, respectively.
