摘　　要：高成本、低活性、低导电性电催化剂阻碍了直接醇类燃料电池的发展。金属气凝胶兼具气凝胶的高度多孔、大比表面积和金属的高导电、高催化活性于一身,在电催化领域展现出巨大的前景,极具研究价值。通过引入非贵金属Bi,发展了一类低成本、高活性的醇氧化合金气凝胶催化剂,为非贵金属基气凝胶催化剂的设计提供了启示。High cost,low activity and low conductivity electrocatalysts hinder the development of direct alcohol fuel cells(DAFC).Metal aerogels(MAs)have both the high porosity and large specific surface area of aerogels and the high conductivity and catalytic activity of metals,which show great prospects in the field of electrocatalysis and have great research value.Therefore,a kind of low-cost and high-activity alcohol oxidation alloy aerogel catalyst was developed by introducing non-noble metal Bi,which provided inspiration for the design of non-noble metal-based aerogel catalyst.
