摘要
贵金属Pt被认为是直接甲醇燃料电池(DMFC)阳极催化剂不可缺少的活性组分,但纯Pt催化剂存在对甲醇催化电氧化反应迟缓、易中毒等缺点,且价格昂贵,限制了DMFC商业化广泛应用。采用纳米Pt基合金催化剂,利用其它组分的调节作用,即可提高催化剂对甲醇氧化的催化活性,又可提高Pt的抗中毒能力,还可降低成本。综述了PtRu、PtPd、PtAu、PtM(M=Fe,Co,Ni)等二元催化剂;Pt-Ru-MoOx,Pt-Ru-Ni等三元催化剂,及四元催化剂在直接甲醇燃料电池的应用研究,并对该领域做了简单的展望。
Pt based nano-particles was considered as the indispensable part of direct methanol fuel cell （DMFC） anode catalysts. The wide commercial applications of DMFC were limited for its slow response, easily poisoning and expensive price of pure Pt catalyst in DMFC anode electro-oxidation of methanol. The catalyst for the methanol oxidation kinetics of catalytic activity could be improved, the anti-poisoning could be increased, the utilization of Pt ability could be improved and the cost could be reduced by adopting nano Pt-based alloys and use of the regulatory role of other components. Application research on the PtRu, PtPd, PtAu, PtM （M=Fe, Co, Ni） binary catalyst, PtRuMo, PtRuNi ternary catalyst, and quaternary catalyst in direct methanol fuel cell were summarized, and a simple outlook in the field was made.
