Selective CO2 hydrogenation over zeolite-based catalysts for targeted high-value products

Abstract

Catalytic conversion of CO₂ to renewable fuels and green chemicals is a promising approach to utilize the large amount of CO₂ generated from fossil fuels. The selectivity of targeted products is a critical parameter for effective CO₂ conversion. However, the uncontrollable C–C coupling limits the selectivity of the desired products. This review focuses on recent advancements in CO₂ hydrogenation over zeolite-based catalysts, with an emphasis on the selectivity of targeted products, such as methanol, olefins, and C₅₊ products. The role of zeolite properties, such as topology, acid sites, and metal–zeolite interactions, in determining product selectivity is comprehensively reviewed. Furthermore, recent progress in designing and modifying zeolite materials with enhanced CO₂ conversion and targeted product selectivity is examined. The current technical challenges and perspectives for developing new zeolite-based catalysts for more efficient CO₂ conversion are also discussed.
