主讲人简介：

Dr. Zhugraduated with a BSc in Materials Chemistry and MSc in Biomedical Engineering from Sichuan University. He then went to Singapore to pursue his PhD degree at Nanyang Technological University in 2009. Upon completion of his PhD in 2013, he worked as a postdoctoral researcher in National University of Singapore. After a three-year postdoctoral research, he joined Central South University in 2017 to serve as a full-time professor. His research work is centered on the development of nanostructured functional materials for energy storage and conversion, such as lithium/sodium ion batteries, supercapacitors, and photo/electro-catalysis. So far, he has authored over 40 research papers in international journals including Adv. Energy Mater., Nano Energy, J. Am. Chem. Soc., Angew. Chem. Int. Ed., J. Mater. Chem. A and so on with a total citation over 3000 times and an H-index of 20.

报告简介：

In order to meet the increasing demands of energy consumption in the next decades(eg. more electric vehicles to realize a cleanurbanization), material scientists worldwide areworkingonefficient, low-cost and low-toxic materials for energy harvesting, conversion and storage from clean energy sources. Suitable functional materials should be explored and utilized for relevant energy storage and conversion devices to address those concerns. However, the current materialsare usually composed of singleconstituentor in hybrids of binary inorganic componentsbut with low surface areas. The poor electroactivitywith less active sitesmayfurtherdeteriorate theelectrochemicalperformancesof the electrodes. Our strategy is todeveloplow-cost transition metal oxide/sulfidebasedmaterialsto enhance the electroactivityas well as the electrochemical active surface area (EASA), because thehybridization of two or more components affords the opportunity to engineer the electronic and/or surface structures. In addition, optimization of surface structures (such as fabrication of hollow or core-shell hierarchical structures) of nanostructures may bring about extra active sites, probably further prompting the electrochemical performances.
