| 摘 要： | 采用间歇式微波法制备了不同Pt、Ni原子比的碳载Pt-Ni催化剂。XRD结果表明,用这种方法制备的催化剂分散得比较好,具有较小的平均粒径,其中Pt-Ni/C(3∶1)催化剂的粒径最小。在旋转圆盘电极上进行氧的还原测试结果表明,当电解质溶液中没有甲醇和有甲醇存在时,Pt-Ni/C(3∶1)催化剂对氧的催化还原活性都很高,说明Pt-Ni/C(3∶1)催化剂对氧的催化还原受甲醇的影响较小。

| Abstract: | The catalyst Pt-Ni supported on carbon with different atomic ratios of Pt to Ni was prepared by the interval microwave method and its performance on the oxygen reduction for direct methanol fuel cell application was investigated. The results show that the active particles of the catalysts prepared in this way were highly dispersed and in small size. The catalyst Pt Ni/C(3∶1) (with the atomic Pt/Ni ratio being 3) has the smallest particle size; it also exhibits the highest activity for oxygen reduction, no matter whether methanol is present or not in the electrolyte, indicating a small effect of methanol on its catalytic performance for oxygen reduction. |
