摘要
为了改善铂基催化剂氧化甲酸的活性,制备磷钼酸和钼酸钠修饰铂电极,并利用循环伏安曲线评价它们对甲酸氧化的电催化活性。结果表明:磷钼酸与钼酸钠修饰铂电极均可提高铂基电极氧化甲酸的催化活性。此外,NiSO4可以提高甲酸在磷钼酸修饰铂电极上的电催化氧化活性。
In order to improve the electrocatalytic activity of Pt based formic acid oxidation, the PM012 and Na2MoO4 modified Pt electrodes were prepared and their electrocatalytic effects on the formic acid oxidation were studied. The electrocatalytic activities for the formic acid oxidation were evaluated with the electrochemical techniques of CV. The result shows that the PMo12 and Na2MoO4 modified Pt electrode can increase the activity of formic acid. In addition when adding NiSO4 solution, the PMo12 modified Pt electrodes can increase the activity of formic acid oxidation
