Abstrakt: Electroreduction of carbon monoxide into high-energy fuel is an excellent energy strategy for sustainable development, but the high yield of multi-carbon products remains a difficult challenge. Inspired by the successful synthesis of various trimer metal clusters and studies on electrocatalysis of CO to C3 products by Cu-based catalysts, Cu 3 supported on N-doped graphene structures (Cu 3 @NG) are investigated as electrocatalysts for CORR toward propanol in this paper. Due to the appropriate Cu-Cu bond length, the moderate charge of the Cu site, mild CO adsorption energy, and 100 % CO coverage, the absorbed 3*CO substance can form the critical *CO-CO-CO intermediate with a rather low kinetic barrier of 0.25 eV. The limiting potential of the whole process for the formation of propanol is just -0.15 V. Our work not only showed that Cu 3 @NG is an excellent catalyst for the formation of propanol with high selectivity at low potential but also indicated that the *CO coverage can greatly reduce the CO hydrogenation potential and bonding of some intermediates such as *CH 2 O. This research will provide a new idea for the material design of products tending to multi-carbon.
