摘要 铂基催化剂是目前直接甲醇燃料电池中阳极氧化催化性能最好的,因此提高铂的利用率和稳定性对推动DMFC的商业化十分重要。合成了一种新的催化甲醇氧化反应(MOR)的催化剂Pt/FeP/CNTs。FeP的掺杂可以显著提高Pt的MOR活性,当FeP的负载量为15%时,Pt/FeP/CNTs的MOR活性最佳,可以达到1325 mAmg■,是Pt/CNTs的3.8倍,Pt/C-JM的2.5倍,稳定性也较好。 Pt-based catalysts are the best anode catalyst in DMFC at present,so enhancing the utility and durability of Pt is very important.In this research,novel Pt/FeP/CNTs catalysts are prepared.It is found that the activity and stability of Pt for methanol oxidation reaction(MOR)can be significantly enhanced while FeP is used as co-catalyst.The Pt/15%FeP/CNTs catalyst shows the best MOR activity of 1325 mAmg-1 Pt,which is 3.8 times of Pt/CNTs and 2.5 times of the commercial Pt/C-JM catalyst.
