Direct converting low concentration CO2 in industrial exhaust gases to high-value multi-carbon products via renewable-energy-powered electrochemical catalysis provides a sustainable strategy for utilization with minimized separation and purification capital energy cost. Nonetheless, the electrocatalytic conversion of dilute into value-added chemicals (C2+ products, e.g., ethylene) is frequently impeded by rate weak carbon intermediates' surface adsorption strength. Here, we fabricate range Cu catalysts comprising fine-tuned Cu(111)/Cu2O(111) interface boundary density crystal structures aimed at optimizing rate-determining step decreasing thermodynamic barriers adsorption.
