摘　　要：考察了不同负载量的Pt/Al2O3催化剂和不同过渡金属助催的Pt/Al2O3催化剂分别催化燃烧含氢尾气和液体甲醇的性能。结果表明,Co和Fe对含氢尾气的催化燃烧有较好的助催效果,Mn和Fe对液体甲醇的催化燃烧有较好的助催效果。添加Fe的0.5%Pt/Al2O3催化剂既可以在室温下起燃液体甲醇,又对催化燃烧含氢气体具有较高的活性,是应用于燃料电池甲醇制氢系统中燃烧催化剂的理想选择。A series of Pt/Al2O3catalysts with different loading and different transition metal promoters were prepared. Their activities for catalytically combusting HE-containing gas and liquid methanol were tested. The results show that the Co and Fe promoters am better for catalytically oxidizing hydrogen, and the Mn and Fe promoters am better for catalytically combusting liquid methanol. The Pt/Al2O3 catalyst adding 0.5% Fe can catalytically combust liquid methanol in room temperature, also is active for catalyst combusting HE-containing gas. Therefore it is a good choice for combustion catalyst in methanol fuel processor for fuel cell.
