Enhancing CO₂ Electroreduction Precision to Ethylene and Ethanol: The Role of Additional Boron Catalytic Sites in Cu-Based Tandem Catalysts.

ABSTRACT: The electrocatalytic conversion of carbon dioxide (CO₂) into valuable multicarbon (C₂₊) compounds offers a promising approach to mitigate CO₂ emissions and harness renewable energy. However, achieving precise selectivity for specific C₂₊ products, such as ethylene and ethanol, remains a formidable challenge. This study shows that incorporating elemental boron (B) into copper (Cu) catalysts provides additional adsorption sites for ^*CO intermediates, enhancing the selectivity of desirable C₂₊ products. Additionally, using a nickel single-atom catalyst (Ni-SAC) as a ^*CO source increases local ^*CO concentration and reduces the hydrogen evolution reaction.
