采用氩弧熔炼法制备Au-Ni合金催化剂.采用循环伏安和计时电流曲线研究甲酸在Au-Ni合金催化剂上的电催化氧化性能,结果与单质金作对比.结果表明,根据氧化主峰电位及电流密度的比较,Au-Ni合金具有比单质Au更好的催化活性.

Gold-nickel alloy was synthesized by arc-melted process. The electro-oxidation of formic acid of Au-Ni alloy was investigated at room temperature by cyclic voitammetry and chronoamperometry. The results were compared with those at a polycrystalline gold electrode surface. R is found that Au-Ni alloy is catalytically more active than pure gold according to the comparison of the main peak potential and current density.
