用平衡吸附法制备了炭载四苯基铁卟啉 铂 (FeTPP Pt/C)复合催化剂 ,比较了经不同温度热处理的FeTPP Pt/C和Pt/C对O2 还原的催化活性和耐甲醇能力。结果表明 ,热处理可改善Pt/C催化剂的耐甲醇能力 ;热处理的FeTPP Pt/C复合催化剂具有较高的氧还原催化活性和良好的耐甲醇能力 ,并且 70 0℃处理的FeTPP Pt/C对O2 还原的催化活性最高。
The FeTPP Pt / C composite catalyst was prepared by the equilibrium adsorption method. The catalytic activities and methanol tolerance of FeTPP Pt / C and Pt / C treated by different temperatures were compared. The results show that the heat treatment can improve the methanol resistance of Pt / C catalyst. The heat-treated FeTPP Pt / C composite catalyst has high catalytic activity for oxygen reduction and good methanol tolerance. FeTPP Pt / The highest catalytic activity of reduction.
