    讲座摘要:

    Inorder to meet the increasing demands of energy consumption in the next decades(eg. more electric vehicles to realize a clean urbanization), materialscientists worldwide are working on efficient, low-cost and low-toxic materialsfor energy harvesting, conversion and storage from clean energy sources.Suitable functional materials should be explored and utilized for relevantenergy storage and conversion devices to address those concerns. However, thecurrent materials are usually composed of single constituent or in hybrids ofbinary inorganic components but with low surface areas. The poorelectroactivity with less active sites may further deteriorate theelectrochemical performances of the electrodes. Our strategy is to developlow-cost transition metal oxide/sulfide based materials to enhance theelectroactivity as well as the electrochemical active surface area (EASA),because the hybridization of two or more components affords the opportunity toengineer the electronic and/or surface structures. In addition, optimization ofsurface structures (such as fabrication of hollow or core-shell hierarchicalstructures) of nanostructures may bring about extra active sites, probablyfurther prompting the electrochemical performances.
