摘要:
以氧化镁（MgO）为载体、H 2PtCl 6·6H 2O和CuCl2溶液为催化剂前驱体，通过浸渍还原法制备Cu3Pt/MgO合金纳米催化剂；采用X射线衍射仪（XRD）、透射电子显微镜（TEM）、X射线光电子能谱（XPS）、能量散射X射线（EDX）和电子顺磁共振（EPR）等对催化剂的形貌、晶型和结构进行表征；考察了Cu3Pt/MgO催化剂对甲醛溶液重整制氢的催化活性，并探究煅烧温度、反应温度和不同金属纳米粒子负载等因素对甲醛溶液重整制氢的影响。结果表明：Cu3Pt/MgO催化剂中Cu和Pt之间相互作用使得Cu3Pt/MgO催化剂具有优异的催化性能，其最佳催化周转频率（TOF）可以达到120 9 h -1 ，比催化剂Pt/MgO、Cu/MgO和CuPt/MgO分别高55、12和6倍。该制备CuPt合金的方法简单，为室温无碱条件下高效产氢提供了新的思路。
