    摘要:

    采用氬弧熔煉法制備Au-Ni合金催化劑。采用循環(huán)伏安和計(jì)時(shí)電流曲線研究甲酸在Au-Ni合金催化劑上的電催化氧化性能，結(jié)果與單質(zhì)金作對比。結(jié)果表明，根據(jù)氧化主峰電位及電流密度的比較，Au-Ni合金具有比單質(zhì)Au更好的催化活性

    Abstract:

    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 voltammetry and chronoamperometry. The results were compared with those at a polycrystalline gold electrode surface. It 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
