| 摘 要： | 以间苯二酚(R)和甲醛(F)为原料,制备R-F炭气凝胶(RF-CAs).继以后者为载体采用浸渍还原法制备铂基催化剂Pt/CA,并比较其与由相同负载工艺制得的以Vulcan XC-72为载体的铂基催化剂Pt/XC72的催化甲醇氧化反应的性能.结果表明,前者具明显高的甲醇氧化催化活性,显示CAs是一种极具潜在竞争力的燃料电池催化剂载体材料.

| Abstract: | Appropriate pore size and its distribution on the surface of catalyst support is very important for im- proving the catalyst activity.With the characteristics of large specific surface area,high electrical conductivity, open and continuous three-dimensional mesoporous network of nanoparticles,controllable pore structure,car- bon aerogels(CAs)has,in recent years,been paid worldwide great attentions as a kind of innovative support material for PEMFC catalyst.In the present study,CAs,noted as RF-CAs,is prepared with the source materi- als of resorcinol(R)and formaldehyde(F),and Pt catalyst supported on RF-CAs(abbreviated to Pt/CA) is prepared,its catalytic performance for methanol oxidation is evaluated and compared with that of Pt supported on Vulcan XC-72 (abbreviated to Pt/XC72).The results showed that the catalytic property of Pt/CA is obvi- ously better and CAs is a kind of very promising support material for PEMFC catalyst. |
