Strategies for the proton-coupled multi-electron reduction of CO₂ on single-atom catalysts

Abstract

Single-atom catalysts have long faced challenges in reactions involving multiple reactants and multiple reaction steps. This review presents the most recent research advances in the development of single-atom catalysts for the deep reduction of CO2.

Progress in Cu-based electrocatalysts for electrochemical CO2 reduction to C2+ products

“…The combustion of fossil fuels has led to a rise in CO 2 emissions, making the neutralization and utilization of CO 2 an urgent concern. [1][2][3] In this context, the CO 2 RR driven by renewable energy has been identified as a promising strategy to convert CO 2 into high value-added products. [4][5][6][7] Notably, compared to C 1 products, C 2+ products (e.g., ethylene, ethanol, n-propanol, and n-butanol) derived from CO 2 RR are highly attractive due to their higher energy density and wider applicability.…”
