A CuLa dual-site catalyst for high-efficiency CO <sub>2</sub> -to-CO electrocatalytic conversion with ultralow overpotential
To achieve high-performance electrocatalytic CO<sub>2</sub> reduction (CO<sub>2</sub>RR) at low potentials, we synthesized an atomically dispersed CuLa/NC catalyst derived from a metalloporphyrin-based metal-organic framework. This catalyst exhibits an exceptional faradaic efficiency of 97%, with a half-cell energy efficiency reaching 91% at an ultra-low potential of -0.20 V for the conversion of CO<sub>2</sub> to CO. Impressively, the reaction can even be powered by a 1.5 V battery. This study offers a refined strategy for the rational design of dual-site catalysts geared toward highly efficient CO<sub>2</sub>RR.
