Dr. Wang Qi graduated from the School of Chemistry and Chemical Engineering of Central South University. He received Ph.D. degree from the School of Materials Science and Engineering of Central South University. During his Ph.D., he was mainly engaged in the design and preparation of metal-based nanomaterials (mainly transition metal alloys, oxides, selenides, etc.) and their applications in the field of catalysis (mainly photocatalytic degradation, electrolyzed water, fuel cell catalysts). The effects of the relative correlation between structure and material were studied by using spherical electron microscopy and in-situ spectrometer. He is currently doing postdoctoral research at the Gu Meng Group of Southern University of Science and Technology. The research interest and direction are mainly to study the structure and phase of the catalyst in the catalytic process by using environmental electron microscopy (ETEM) and double spherical electron microscopy (Double Cs-corrected S/TEM) combined with energy spectrum (EDS) and electron energy loss spectroscopy (EELS). The dynamics of the study, from the atomic level, study the activity and stability of catalysts in the field of new energy materials.
