Abstract
AbstractSolar energy‐driven CO2 reduction and H2 evolution is considered as a very promising pathway to address energy shortage and environmental issues. Multivariate metal organic frameworks (MTV‐MOFs) as a class of distinctive crystal porous materials are assembled from different metals or different ligands via one pot reaction or postsynthesis approach. Recently, MTV‐MOFs have gathered significantly interest in the field of photocatalytic CO2 reduction and H2 evolution owing to their excellent structural stability, tailorable light‐absorption, and catalytic abilities. In this review, incorporating different functional ligands or metals into the parent MOFs are focused on to boost the photocatalytic performance of MTV‐MOFs. First, the synthesis and unique advantages of MTV‐MOF‐based photocatalysts are introduced. Next, an overview on the recent advance on MTV‐MOFs for solar‐to‐chemical energy conversion is summarized into three main categories, consisting of mixed‐metal MOFs, mixed‐ligand MOFs, and mixed‐metal and mixed‐ligand MOFs. Finally, future perspectives and challenges in CO2 conversion and H2 evolution over MTV‐MOF‐based photocatalysts are presented.
