摘要：

与非贵金属形成合金是一种能大幅减少电催化剂中贵金属用量的有效方法,且形成合金有利于催化性能提升.本文引入了一种混合溶剂体系,通过采用高质量铜纳米线作为部分牺牲模板合成了多孔均一、表面粗糙的Pt Au Cu三元纳米管.实验表明金的引入是催化剂甲醇氧化(MOR)和甲酸氧化(FAOR)性能提升的一个关键因素.其MOR和FAOR质量活性分别达到了1698.8 m A mg-1Pt(0.9V)和1170 m A mg-1Pt(0.65V).由于CO*不可逆的吸附在金的表面而非有催化活性的铂表面,这种三元纳米管催化剂表现出了优异的催化稳定性和结构稳定性.此外,这种合成方法可以用于合成其他的新型双功能催化剂.
