Porphyrin‐Based Covalent Organic Frameworks for CO 2 Photo/Electro‐Reduction

Abstract Photo/electro‐catalytic CO 2 reduction into high‐value products are promising strategies for addressing both environmental problems and energy crisis. Duo to their advantageous visible light absorption ability, adjustable optic/electronic properties, definite active center, post‐modification capability, and excellent stability, porphyrin‐based covalent organic frameworks (COFs) have emerged as attractive photo/electro‐catalysts towards CO 2 reduction. In this review, the research progress of the porphyrin‐based COFs for photo/electro‐catalytic CO 2 reduction is summarized including the design principles, catalytic performance, and reaction mechanism. In addition, this review also presents some challenges and prospects for the application of porphyrin‐based COFs in photo/electro‐catalytic CO 2 reduction, laying the base for both fundamental research and application efforts.
