摘要 对Ce/TiO2催化剂的碱金属中毒机理进行了系统性研究.采用浸渍法和溶胶凝胶法进行实验,发现碱金属对催化剂活性有抑制作用,并通过一系列表征分析了导致这一结果的原因. A systematic study of the catalyst poisoning is carried out based on the poisoning mechanism of alkaline metal in Ce/TiO2 catalyst. A series of catalyst is carried in the method of impregnation and sol-gel. It is found that alkaline metal has inhibitory effect on catalyst activity. The cause of the result is analyzed through a series of characterization.
