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

Photo/electro-catalytic CO₂ 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 CO₂ reduction. In this review, the research progress of the porphyrin-based COFs for photo/electro-catalytic CO₂ 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 CO₂ reduction, laying the base for both fundamental research and application efforts.
