On February 14, 2025, at the invitation of Professor Wang Leyu, He Hongyan, a researcher from the Institute of Process Engineering, Chinese Academy of Sciences, visited Beijing University of Chemical Technology National Key Laboratory for Effective Utilization of Chemical Resources, The College of Chemistry and the High Precision Center, under the auspices of Professor Wang Leyu, made an academic report entitled "Structural Analysis of Nanoconfined Ionic Liquids and Research on Enhancing CO2 Separation".
Researcher He Hongyan has long been engaged in the research of interfacial chemical thermodynamics based on ionic liquids, intelligent design of ionic liquid based functional materials and green chemical processes. So far in Science Adv.、Nature Commun.、PNAS、JACS、Angew. Chem. Int. Ed.、Adv. Mater.、AIChE J.、Chem. Eng. Sci. And other journals published more than 120 academic papers. Presided over the National Science Fund for Distinguished Young Scholars, the National Science Fund for Distinguished Young Scholars, the National Key Research and Development Program for Young Scientists, the Youth Team in Basic Fields of the Chinese Academy of Sciences and other projects; He has won awards and honors such as Young Talents in Propaganda of the Central Propaganda Department, Science and Technology Promotion Development Award of the Chinese Academy of Sciences, Hou Debang Chemical Science and Technology Innovation Award, and Green Chemistry Emerging Researchers. Executive Editor of Advisory Board Member and Green Energy Environment. of ChemComm and J. Chem. Eng. Data; Vice director of Beijing Key Laboratory of Ionic Liquid Cleaning Process, vice chairman of Youth Working Committee of Chinese Chemical Society, etc.
Researcher He Hongyan focused on the structure analysis and performance control of ionic liquids under the condition of nano scale confinement. Through the combination of multi-scale simulation and experiment, he deeply discussed the ion arrangement, dynamic behavior and confinement effect of ionic liquids at the nanoscale, especially how this confinement effect should enhance the separation process of gases such as carbon dioxide. Based on the guidance of theoretical research, the confined ionic liquid composite membrane materials and components were designed and prepared, providing scientific reference for the development of new technologies for CO2 separation enhanced by nano confined. After the report, teachers and students actively asked questions, and researcher He Hongyan carefully answered.
