Molecule-based heterogeneous photocatalysts without noble metals are one of the most attractive systems for visible-light-driven CO2 reduction. However, reports on this class still limited, and their activities quite low compared to those containing metals. Herein, we report an iron-complex-based photocatalyst reduction with high activity. The key our success is use a supramolecular framework composed iron porphyrin complexes bearing pyrene moieties at meso positions. catalyst exhibited activity under visible-light irradiation (29100 μmol g-1 h-1 CO production, selectivity 99.9%), which highest among relevant systems. performance also excellent in terms apparent quantum yield production (0.298% 400 nm) stability (up 96 h). This study provides facile strategy create highly active, selective, stable utilizing

Published: July 29, 2024

Abstract Electrocatalytic CO 2 reduction (ECR) powered by renewable electricity is a promising technology to mitigate carbon emissions and lessen the dependence on fossil fuels toward carbon‐neutral energy cycle. Metal–organic frameworks (MOFs) their derivatives, due excellent intrinsic activity, have emerged as materials for ECR high‐demand products. However, challenges such unsatisfactory efficiency, selectivity, relatively low production rates hinder industrial scalability. Here, comprehensive critical review presented that summarizes state‐of‐the‐art progress in MOF‐based MOF‐derived electroreduction catalysts from design functionality perspectives. The fundamentals of reaction (CO RR) over heterogeneous catalysts, mechanisms, key faced are described first establish solid foundation forthcoming in‐depth analyses. MOF's building blocks, properties, shortcomings pertinent including conductivity stability, systematically discussed. Moreover, discussions provided design, fabrication, characterization, RR activity pinpoint intricate structure‐property‐performance relationship. Finally, recommendations put forward enhancing MOF electrocatalysts durability. This work may serve guideline developing high‐performance MOF‐related RR, benefiting researchers working this growing potentially game‐changing area.
