Regulating the Second Coordination Sphere of Cu-Salen-Covalent Organic Frameworks via Substituent Engineering for Electrocatalytic CO2 Reduction to CO.
Single-atom catalysts (SACs) have shown great potential for electrocatalytic CO2 reduction reaction (CO2RR) due to high activity, but the CO2RR selectivity is severely restricted by competing hydrogen evolution reaction (HER). Modifying the electronic structure of single-atom sites to inhibit water adsorption while pro...
