Electrocatalytic Oxidation of Methaol at GlassyCarbon Electrode with Platinum Microparticles

利用循环伏安法等电化学方法研究了甲醇在铂微粒修饰的玻碳电极上的电催化氧化.结果表明,铂微粒修饰玻碳电极(GC Pt)对甲醇电化学氧化呈现较高的催化活性,活化后的玻碳电极再修饰铂微粒表现更高的催化活性.其催化活性的大小与铂载量有关.同时测定了甲醇电催化氧化反应的动力学参数.

Cyclic voltammerty has been used to prepare the glassy carbon electrode with platinum microparticles,and high electrocatalytic activity in oxidation of methanol in the surroundings of acid has been found by the electrode.In the same way,after the glassy carbon electrode with platinum microparticles was activated,a higher electriocatalytic activity has been shown in oxidation of methanol in the surroundings of acid.And the parameter of kinetics of electrode process has been detected.
