Engaged in research on CO₂ conversion into high-value products, design and synthesis of ionic liquids and catalytic materials, and scaling up of catalytic reaction engineering

She enrolls students major in chemical engineering, applied chemistry, industrial catalysis, materials, and polymers.

She obtained her Ph. D degree from the Institute of Process Engineering, Chinese Academy of Sciences in 2018. She was selected into the Young Elite Scientists Sponsorship Program by CAST in 2022. She possesses a solid foundation and extensive experience in applied basic research, including ionic liquid structure design, catalytic material design and preparation, as well as catalytic reaction process scaling. As a key member, she participated in the development of a new technology for synthesizing carbonates from CO2 catalyzed by ionic liquids. She successfully tackled the challenges of large-scale preparation of ionic liquids and achieved industrial preparation and application of ionic liquids. This new technology passed the appraisal of scientific and technological achievements, and she was awarded the first prize for technological invention by the China Petroleum and Chemical Industry Federation in 2022 as one of the contributors.
