The applicant has investigated the surface and interface characteristics, and reaction mechanism of electrocatalytic reduction of carbon dioxide. The applicant has made innovative achievements in structural design of the active center, dynamic evolution of the active center induced by electrochemical environment, and regulation rule of the electrochemical elementary reaction. (1) Developing a novel strategy of constructing surface and interface structure with unsaturated coordination for efficient electrocatalytic reduction of carbon dioxide. (2) Clarifying the dynamic structure of the active center under the reaction conditions and regulation rule of product selectivity. (3) Establishing effective methods to control the important elementary reactions of carbon dioxide electrolysis by optimizing the electrode surface and interface structure. The applicant has assembled carbon dioxide electrolysis system prototype to achieve efficient synthesis of C2+ products at industrial current density. The applicant has published 52 papers in scientific journals such as Angew. Chem.(6), J. Am. Chem. Soc.(1), Adv. Mater.(3), Energy Environ. Sci.(2), etc., as the corresponding or co-corresponding author in the past five years. The applicant will extend the scientific understanding of electrocatalytic surface and interface structure to the electrochemical interface of “gas diffusion electrode/solid electrolyte” in carbon dioxide electrolysis device, and investigate the microstructure and dynamic evolution of the electrochemical interface under the reaction conditions, and reveal the relationship between the structure of the electrochemical interface and the performance of carbon dioxide electrolysis device.
