In August 2022, he joined the Beijing Key Laboratory of Chemical Power and Green Catalysis, School of Chemistry and Chemical Engineering, Beijing Institute of Technology, as an assistant professor and master supervisor. He is mainly engaged in the research of catalysts and reactors related to multiphase electrocatalytic conversion of small energy molecules. He has a solid foundation and rich experience in the design and synthesis of high-efficiency catalysts, the systematic research of electrocatalytic reaction mechanism and the development of new electrocatalytic reactors. Participated in a number of national and provincial projects and enterprise research and development projects. In Angew.Chem.Int.Ed., Appl.Catal. B-Environ., Chem.Eng. J., Prog.Energ.Combust. Sci., ChemSusChem, J. Clean.Prod. He has published more than ten papers in other journals.

(1) Basic research:
In the field of electrocatalytic CO2/CO conversion, efficient methods such as in-situ polymerization coating method, controlled impregnation method and impregnation-in-situ growth method have been developed to prepare a series of polyionic liquid-mono/bimetallic hybrid catalysts with different cationic frameworks, different anion compositions, and different metal types and ratios. Highly selective conversion of CO2/CO to high value-added chemicals at industrial grade current density (100 ~ 1000 mA cm-2). In the field of electrocatalytic N2 conversion, a series of iron-based catalysts have been developed to directly produce NH3 by the reaction of N2 and H2O under mild conditions (atmospheric pressure and medium low temperature).
In the field of new electrocatalytic reactor, a gas-liquid equilibrium flow electrolysis system has been developed to realize the dynamic balance of reaction gas and electrolyte near the catalytic layer. In situ fluorescence flow electrolytic cell was developed and combined with in situ Raman flow electrolytic cell to provide a powerful tool for on-line analysis of reactant supply and surface/interface information under reaction conditions. The medium and low temperature submolten salt gas electrolytic cell was developed to realize the in-situ efficient supply of insoluble reaction gas in submolten salt system.
(2) Application research and development:
As the backbone of the research, I participated in the research of the cooperative R&D project (new green technology of adiponitrile), responsible for the green research of the electrolytic dipolymerization of acrylonitrile into adiponitrile, and used ionic liquids to strengthen the supply of reactants and improve the product selectivity, so as to make the route greener, more energy saving and cleaner. Responsible for the research and development of preparation methods for industrial carbonylation catalysts, and developed feasible methods to prepare a variety of high-value didentate phosphine ligands using bulk chemicals as raw materials.
