Abstract:The dehydrogenation of ethane by CO2 to ethylene（ CO2 -ODH）has important research and application values.This review focuses on the reaction mechanism of CO2 oxidation dehydrogenation of ethane and the key scientific issues (selective cleavage of C-C/C-H bonds）. Effects of electronic and geometric properties of active sites，interface site efcts，metal-support interactions，surface acid-base properties，heteroatom doping，catalyst deactivation and regeneration on performance and structure-activity relationship of CO 2 -ODH reaction are summarized.Moreover,this review introduces theapplication of noble metal catalystsand non-noble metal catalysts in CO 2 -ODH reaction，and proposes the methods used for constructing eficient ethane oxidation dehydrogenation catalystsbased on the reaction mechanisms and key scientific issues.Finally，the research progress of CO 2 -ODH reactioncatalysts aresummarized.Research resultsprovide referenceand theoretical guidance for the developmentof CO 2 -ODH catalyst with goodactivity，product selectivityand stability，and provide beneficial support for its further commercial application.

Key words: CO2 oxidative dehydrogenation of ethane； catalyst； reaction mechanism； active site； structure-activity relationship
