摘要
采用化学原位一步还原法制得纳米铂修饰玻碳电极,并测试比较了其在酸性介质和碱性介质中对乙二醇氧化的电催化作用。结果表明,相比铂片电极,纳米铂修饰玻碳电极对乙二醇表现出更好的电催化性能,且该修饰电极在碱性介质中对乙二醇的催化作用更明显。
A glassy carbon electrode modified with spherical platinum nanoparticles was fabricated by a one- step in situ chemical reduction growth method. Efficient electrocatalytic activity of platinum nanoparticles-attached glassy carbon electrode towards the oxidation of ethylene glycol was observed and compared in acidic solution and alkaline solution. Compared with the bulk Pt electrode, the modified electrode significantly improved the electrocatalytic activity toward the oxidation of ethylene glycol. Furthermore, the catalysis in alkaline solution was more remarkable than that in acidic solution.
