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.
