Abstract
The typical reaction mechanism for the dehydrogenation of ethanol to synthesize ethyl acetate was described,and the research progress of Cu-based catalysts(Cu-Cr,Cu-Zr,Cu-Zn systems),noble metal catalysts and other catalyst systems in the field of dehydrogenation of ethanol to synthesize ethyl acetate in recent years was reviewed,and the analysis showed that Cu-based catalysts show more significant advantages in catalytic performance,manufacturing cost and so on.The future research direction of Cu-based catalysts for the dehydrogenation of ethanol to synthesize ethyl acetate mainly focuses on the composition of the catalysts and the content of each component,the preparation methods and conditions of the catalysts,as well as the combination of various types of characterization techniques and theoretical calculations to deepen the understanding of the catalysts'structure-activity relationship.
