| 摘 要： | 采用TiO2溶胶法,在不同条件下制备了碳载Pt-TiO2催化剂.通过循环伏安法(CV),计时电流法(CA)对碳载Pt-TiO2催化剂在甲醇上的电氧化特性进行了研究.结果表明不同条件制备的催化剂对甲醇的电催化氧化的催化活性不同.其中加入聚乙二醇所制得的Pt-TiO2/C催化剂对甲醇的氧化具有最佳的电催化活性和稳定性.

| Abstract: | Carbon supported Pt-TiO2 catalysts were prepared by colloid method on different conditions. The Home-made Pt-TiO2/C catal,ysts were used for methanol oxidation in acidic solution. The catalysts prepared have been characterized by cyclic voltammetry (CV) and Amperometric i-t techniques. The catalyst prepared by adding polyethylene glycol has the highest activity and stability for methanol electrooxidation among the catalysts prepared. |
