耐甲醇氧还原复合催化剂四苯基铁卟啉-铂的研究
FeTPP-Pt/C as Methanol-tolerant Co-catalysts for Oxygen Reduction
【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 70 0℃处理的FeTPP Pt/C对O2 还原的催化活性最高。
【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.
