Prof. Xue WANG

PhD in Chemistry, Xiamen University
Staff title
Assistant Professor

Prof. Xue Wang received her Ph.D. degree in Chemistry from Xiamen University in 2015 under the supervision of Prof. Zhaoxiong Xie and Prof. Younan Xia. During her graduate studies, she worked at the Georgia Institute of Technology as a visiting graduate student (2013-2015). After her Ph.D. graduation, she was appointed as associate professor at Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (2016-2017). Then she went to University of Toronto and worked as a postdoctoral fellow with Prof. Ted Sargent, prior to joining the City University of Hong Kong as an assistant professor in the School of Energy and Environment in January 2023. Prof. Wang’s research expertise covers nanomaterial design, electrocatalysis, and reaction engineering, with a particular emphasis on energy-related applications.

Research Interests

With increasing global energy usage, combined with intensifying anthropogenic climate change, the future energy system is required drastic modification: moving from fossil fuels to low-carbon energy sources. Although energy potential from solar and wind exceeds global energy consumption many times over, we are challenged to develop technologies for efficient conversion and storage of renewables.

Within this broad landscape, XUE WANG group’s research focuses on science and engineering for decarbonization of the energy sector using electrocatalysis approach. Through the combination of catalyst design, mechanism investigation, and reaction engineering, we aim to develop efficient CO2 electrochemical conversion technologies for renewable energy storage & conversion, electrosynthesis of chemicals/fuels, and climate change mitigation, as well as unravel the physical and chemical events at the molecular level during the electrocatalysis processes.
