Exploring the Influence of Morphological Variations in M/CeO2 Catalysts for Enhanced CO2 Hydrogenation to C1 Products

Abstract

M/CeO2 catalysts (M=Metal and metal oxide) have garnered significant attention due to their exceptional catalytic performance in thermal, photocatalytic, and electrocatalytic applications. It has been demostrated that the morphology and structure of M/CeO2 catalysts play a crucial role in enhancing catalytic reactions. The influence extends not only to the regulation of reaction pathways but also to significantly impacting the reaction activity, which is of paramount importance in optimizing catalytic performance of CO2 hydrogenation. This review comprehensively focus on the impact of various morphological structures of M/CeO2 in the catalytic conversion of CO2 to C1 products such as CO, CH4, and CH3OH, exploring the intrinsic relationships between catalyst morphology and reaction properties. Additionally, the reaction mechanisms associated with different morphological forms of M/CeO2 catalysts are discussed in-depth, aiming to uncover the underlying complexities of C1 product formation.
