Abstract:

The rapid development of global industrialization has led to excessive emissions of carbon dioxide(CO2),which in turn has led to increasingly severe green house effect.The catalytic conversion of CO2 into high value-added chemicals can achieve the recycling of carbon resources and energy conservation and emission reduction.With the continuous deepening of research on CO2 thermal catalytic conversion and the construction of relay-catalysis systems,researchers had continuously achieved new scientific research results in the preparation of high value-added chemicals through CO2 relay catalysis.By summarizing the mechanism and advantages of relay-catalysis reactions,as well as the recent structural characteristics,reaction mechanisms,and catalytic performance characteristics of various catalysts in the relay-catalysis reactions of CO2 to prepare low-carbon olefins,aromatics,and oxygen-containing hydrocarbons,a detailed analysis was conducted on the role of bifunctional catalysts formed by the combination of various metal compounds and different molecular sieves in the reaction,and the key factors affecting catalytic performance on bifunctional catalysts were discussed.The adjustment measures of the structure,morphology,and binding mode of the active components of bifunctional catalysts in future relay-catalysis reactions were prospected,in order to improve the conversion rate of CO2 and the selectivity of the target product.

Key words: relay-catalysis, CO2, high value-added chemicals, metallic oxide, molecular sieves
