采用化学还原沉积法制备了Ｐｔ－ＷＯ３／Ｃ、Ｐｔ－Ｒｕ／Ｃ和Ｐｔ－Ｒｕ－ＷＯ３／Ｃ系列催化剂．通过循环伏安与电流－电位极化研究了甲醇在不同催化剂／Ｎａｆｉｏｎ膜电极上的电催化氧化．结果表明，三种催化剂的催化活性顺序为：Ｐｔ－Ｒｕ－ＷＯ３／Ｃ＞Ｐｔ－Ｒｕ／Ｃ＞Ｐｔ－ＷＯ３／Ｃ．同时研究了甲醇浓度和催化剂的配比对阳极性能的影响．
Pt-WO3 / C, Pt-Ru / C and Pt-Ru-WO3 / C catalysts were prepared by chemical reduction deposition. Electrocatalytic oxidation of methanol over different catalyst / Nafion membrane electrodes was investigated by cyclic voltammetry and current-potential polarization. The results showed that the order of catalytic activity of the three catalysts was Pt-Ru-WO3 / C> Pt-Ru / C> Pt-WO3 / C. The effects of methanol concentration and catalyst ratio on the anode performance were also studied.
