Abstract

Carbon dioxide reduction has been regarded as a promising strategy for the generation of value-added multi-carbon compounds. Taking advantage of the synergy of the distinct chemical characters of adsorption sites, the single-atom Sc-doped Cu(111) surface exhibits excellent performance for C2H4 selectivity. O is more strongly bound to Sc than C to Cu, leading to the facilitation of CO2 activation and C2H4 desorption. The Sc dopant promotes C–C dimerization through the CO dimer into COCO, which is difficult to occur on the pristine Cu(111), and the COCO─involved reaction pathway is favorable both in thermodynamics and kinetics. This study sheds light on nanocatalyst design for reaction products with different chemical characters from reactants. Typically, the control of the electron-deficient and electron-sufficient sites on catalyst surfaces is beneficial for chemical reactions with oxygenated reactants and hydrocarbon products.
