Construction of stable Cu+/Cu0 sites at the fullerene/Cu(OH)F interface to boost the electroreduction of CO2 to C2+ products

Abstract

Herein, the reduction of the Cu oxidation state during the CO₂ electro-reduction reaction (CO₂RR) is effectively inhibited by depositing C₆₀ supramolecular clusters onto the Cu(OH)F surface. By utilizing the unique electronic buffering capacity of C₆₀, a significant number of Cu⁰/Cu⁺ sites are created, leading to a remarkable faradaic efficiency of C₂₊ products up to 76.9% and exceptional stability.
