异丙醇探针反应表征Ce-Mo-O催化剂的酸性与氧化还原性

摘要

Acidic and redox properties are two important aspects of metal oxide catalysts for selective oxidation reactions. Various methods have been used to characterize these properties, of which the isopropanol conversion is a useful probe reaction that can give qualitative information. It is well known that acidicsites catalyze the dehydration of isopropanol to propylene and basic sites catalyze the dehydrogenation of isopropanol to acetone.
