Construction of stable Cu/Cu sites at the fullerene/Cu(OH)F interface to boost the electroreduction of CO to C products.

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

Construction of Dual-Active Sites by Interfacing with Polyhydroxy Fullerene on Nickel Hydroxide Surfaces to Promote CO Deep Photoreduction to CH.

Due to the complex series of elementary steps involved, achieving deep photoreduction of CO to multielectron products such as CH remains a challenging task. Therefore, it is crucial to strategically design catalysts that facilitate the controlled formation of the crucial intermediates and provide precise control over the reaction pathway. Herein, we present a pioneering approach by employing polyhydroxy fullerene (PHF) molecules to modify the surface of Ni(OH), creating stable and effective synergistic sites to enhance the formation of CH from CO under light irradiation.
