耐甲醇氧还原复合催化剂四苯基铁卟啉-铂的研究
摘要:
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700℃处理的FeTPP-Pt/C对O2还原的催化活性最高。

FeTPP-Pt/C as Methanol-tolerant Co-catalysts for Oxygen Reduction
Abstract:
FeTPP-Pt/C co-catalysts were prepared by a balance-adsorption method.The activity for oxygen reduction reaction (ORR) and methanol-tolerant ability of heat-treated FeTPP-Pt/C and Pt/C were compared.The results showed the methanol-tolerant ability of Pt/C was improved by heat-treatment.Heat-treated FeTPP-Pt/C co-catalysts owned higher activity for ORR and better methanol-tolerant ability,especially FeTPP-Pt/C heat-treated at 700℃ has the highest activity for ORR.
