Electrochemical CO2 reduction reaction on cost-effective oxide-derived copper and transition metal–nitrogen–carbon catalysts
Résumé
The electrochemical CO 2 reduction reaction (CO 2 RR) either to generate multi-carbon (C 2+) or single carbon (C 1) value-added products provides an effective and promising approach to mitigate the high CO 2 concentration in the atmosphere and promote energy storage. However, cost-effectiveness of catalytic materials limits practical application of this technology in the short term. Herein, we summarize and discuss recent and advanced works on cost-effective oxide-derived copper (OD-Cu) catalysts for the generation of C 2+ products (hydrocarbons and alcohols) and transition metal-nitrogen-doped carbon (M-N-C) electrocatalytic materials for C 1 compounds production from CO 2 RR. We think they represent suitable electrocatalyst candidates for scaling up electrochemical CO 2 conversion. This short review may provide inspiration for the future design and development of innovative active, cost-effective, selective and stable electrocatalysts with improved properties for either the production of C 2+ (alcohols, hydrocarbons) or carbon monoxide from CO 2 RR. 2
