Single-Atom Catalysts on Covalent Organic Frameworks for CO₂ Reduction

The long-unresolved issue of CO2 release and the resulting atmospheric change can be solved through application effective catalysts. Thus, single-atom catalysts (SACs) have been rapidly developed for reduction reaction (CO2RR), as they show improved catalytic metrics enable generation C2+ products. Among numerous novel SACs, such those based on graphene, metal–organic frameworks, covalent organic frameworks (COFs), COF-based SACs are most promising owing to their high stability, porosity, designability. Considering this, we describe two synthesis methods SACs: ligand coordination macrocycle backbone integration, explore pros cons each. We also propose routes designing superior evaluate factors influencing CO2RRs over metal loading types.
