铂、钌共修饰的氧化钛电极对甲醇的电催化氧化
摘要:
首次发现用电化学阴极还原-阳极氧化法制得的Pt-TiOx/Ti和Pt-Ru-TiOx/Ti电极对甲醇氧化呈现出较高的电催化活性和稳定性,其中Pt-Ru-TiOx/Ti电极比Pt-TiOx/Ti电极具有更好的性能.实验结果表明,这两种电极对甲醇氧化具有高电催化活性是由于Pt、Ru得到了较好的分散,较好的稳定性可归结于Pt、Ru与TiOx 协同作用导致弱的CO吸附而使电极不易中毒.

Electrocatalytic Oxidation of Methanol on the Pt and Ru Modified Titanium Oxide Electrode
Abstract:
It was found for the first time that the Pt-TiOx/Ti and Pt-Ru-TiOx/Ti electrodes prepared by an electrochemical reduction-oxidation method show the excellent electrocatalytic activity and stability for the oxidation of methanol.The performance of the Pt-Ru-TiOx/Ti electrode is better than that of the Pt-TiOx/Ti electrode.Their high electrocatalytic activities for methonal oxidation is due to the high dispersion of Pt and Ru particles.The good stabilities can be attributed to the synergistic effect among Pt、Ru and TiOx which leads to the weak adsorption of CO at the electrodes, avoiding the electrodes being poisoned.
