摘要
用微波法在三种不同反应体系:蒸馏水、异丙醇、乙二醇中,制备三种Pt-Co/C催化剂,运用循环伏安和线性扫描的方法,测试了不同反应体系中制备的Pt-Co/C催化剂在H_2SO_4和HClO_4溶液中,有、无CH_3OH时,对O_2的电催化还原情况,并考察了不同反应体系制备的三种催化剂抗甲醇性能。由实验结果可知,三种不同反应体系制备的Pt-Co/C催化剂中,在乙二醇反应体系中制备的Pt-Co/C(3)催化剂对O_2电催化还原性能最好,同时具有较好的抗甲醇能力。
With microwave method in three different reaction systems:distilled water,isopropyl alcohol,ethylene glycol,three kinds of Pt-Co/C catalysts were prepared.By cyclic-voltammetry and scanning line,the prepared Pt-Co/C catalysts by different reaction systems,in H2SO4and HClO4solution,with or without CH3OH,the electrocatalytic oxidation of the reduction of O2were tested,and the effects of the anti methanol performance of three kinds of catalysts were also measured.The experiment results show that Pt-Co/C(3)catalyst not only has the best performance,but also has better methanol resistance.
