摘要
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．
A series of catalysts, Pt-WO_3/C, Pt/Ru/C and Pt-Ru-WO_3/C were prepared by chemical reduction deposition. Electrocatalytic oxidation of methanol on different catalyst/Nafion membrane electrodes was studies by cyclic voltammetry and currentpotential polarization. The results indicated that the catalytic activity order of different catalysts is as follows: Pt-Ru-WO_3/C>Pt-Ru/C>Pt-WO_3/C. At the same time, influences of methanol concentrations and catalyst proportion on performances of anodes were also studies.
