讲座摘要:

In order to meet the increasing demands of energy  consumption in the next decades (eg. more electric vehicles to realize a clean  urbanization), material scientists worldwide are working on efficient, 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 materials are usually composed of single constituent or in  hybrids of binary inorganic components but with low surface areas. The poor  electroactivity with less active sites may further deteriorate the  electrochemical performances of the electrodes. Our strategy is to develop  low-cost transition metal oxide/sulfide based materials to enhance the  electroactivity as well as the electrochemical active surface area (EASA),  because the hybridization 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.
