Recent Development of Porous Porphyrin‐based Nanomaterials for Photocatalysis

Abstract Porphyrins and their derivatives are abundant in nature and play an important role in plant photosynthesis. To mimic the photosynthetic reactions in plants, researchers have developed numerous porphyrin‐based nanomaterials to convert light into chemical energy. And the porous porphyrin‐based nanomaterials attract great interest in photocatalysis owing to their high surface areas, designable structure, and favorable photocatalytic behavior. In this review, we highlight the recent progress of porous porphyrin‐based nanomaterials for photocatalysis. We offer a structured description of the main classes of the porous porphyrin‐based nanomaterials which consist of metal‐organic frameworks (MOFs), covalent‐organic frameworks (COFs), amorphous porous organic polymers (APOPs), and hydrogen bonding‐organic frameworks (HOFs). Strategies to improve their photocatalytic behavior in respect of how to boost the photoexcited electron‐hole separation and increase the accessible active sites are mainly highlighted. At last, the prospects and challenges of porous porphyrin‐based nanomaterials for photocatalysis are also discussed.
