Functionalized MOF‐Based Photocatalysts for CO2 Reduction

Abstract Metal‐organic frameworks (MOFs) materials have become a research forefront in the field of photocatalytic CO 2 reduction attributed to their ultra‐high specific surface area, adjustable structure, and abundant catalytic active sites. Particularly, MOFs can be facilely tuned to match CO 2 photoreduction by utilizing post‐modification of metal nodes, functionalization of organic linkers, and combination with other active materials. Herein, the recent advances in the construction strategy of MOF‐based photocatalysts materials for CO 2 reduction are highlighted. Some systematic modification strategies on MOF‐based photocatalysts are also discussed, such as modification of metal sites and organic ligands, construction of heterojunction, introduction of single/dual‐atom, and strain engineering. Finally, the future development directions of MOF‐based photocatalysts in the field of CO 2 reduction are presented.
