分子印刷技术铂微粒修饰电极及甲醇的电催化氧化

Electrode Modified with Platinum Microparticles Prepared by Molecular Imprinting Technology and Electrocatalytic Oxidation of Methanol

利用分子印刷技术(MolecularImprintingTechnology,MIT),将铂微粒沉积到谷胱甘肽自组装膜的针孔上,并用循环伏安法研究了甲醇在该电极上的电催化氧化行为。实验结果表明,该电极对甲醇电化学氧化呈现出较高的催化活性,活性高低与载铂量、溶液pH值及电极表面铂微粒所处的微环境有关。

The electrocatalytic oxidation of methanol on platinum microparticles electrode, which was prepared by Molecular Imprinting Technology (MIT) to deposit platinum micropartides onto a self-assembled monolayer of Glutathione (GSH), was studied by means of cyclic voltammetry. The modified electrode exhibited high electrocatalytic activity for oxidation of methanol, which depended on the platinum loading capacity, pH of electrolytes and the environment of platinumparticle on the electrode surface.
