Abstract
Supported bimetallic PdCu catalysts with precisely controlled Pd/Cu ratios were prepared and characterized by combining sample averaged and microscopic techniques. The active-site isolation effect on reactivity and reaction pathway control with different extent of Pd ensembles in acetylene hydrogenation is unravelled systematically.
摘要
制备了具有精确控制的钯/铜比例的负载型双金属钯铜催化剂，并通过结合样品平均和微观技术对其进行了表征。系统地揭示了在乙炔加氢反应中，不同程度的钯原子簇对活性位点隔离效应以及反应途径控制的影响。
