About author:
Prof. Gang Liu (College of Chemistry, Jilin University) received his B.A. (2002) and Ph.D. (2007) from College of Chemistry, Jilin University. He joined the same college and was promoted to full professor in 2019. He did postdoctoral research on photocatalysis at Dalian Institute of Chemical Physics (Chinese Academy of Sciences) and was a visiting professor at Dalhousie University (Canada). Currently, he is the director of the Department of Physical Chemistry. He has published more than 70 refereed papers and 10 patents, and two patents are being used commercially in industrial processes. He has won some awards, such as Science and Technology Progress Awards of Jilin Province and The Young Talent Award from Tang Auchin Foundation. His current scientific interests are focused on selective catalytic oxidation and energy photocatalysis. He was invited as a young member of the 5th and 6th Editorial Board of Chin. J. Catal.
