摘要
采用湿法浸渍在自制的氧化铈载体上制备了负载的贵金属催化剂 5%Pt/CeO2、5%Pd/CeO2 和5%Rh/CeO2,采用分步浸渍法制备了双金属催化剂 5%Pt-0.5%Pd/CeO2、5%Pt-0.5%Rh/CeO2、5%Pt-0.5%Fe/CeO2、5%Pt-0.5%Co/CeO2 和5%Pt-0.5%Ni/CeO2,考察它们在糠醛选择性加氢反应中的催化性能.
Abstract
Supported noble metal catalysts,5%Pt/CeO2,5%Pd/CeO2 and 5%Rh/CeO2,were prepared on a self-made ceria support using a wet impregnation method.Bimetal catalysts,5%Pt-0.5%Pd/CeO2,5%Pt-0.5%Rh/CeO2,5%Pt-0.5%Fe/CeO2,5%Pt-0.5%Co/CeO2 and 5%Pt-0.5%Ni/CeO2,were prepared using a step-by-step impregnation method,and their catalytic performance in the selective hydrogenation of furfural was investigated.
