报告摘要:The developments of novel nanomaterials and nanocomposites have attracted tremendous research attention for energy and environment related applications. The exploration of new, safe, and inexpensive rechargeable batteries with high energy-density electrodes is a key to integrate the renewable sources such as solar and wind, and address the sustainability issues. A variety of facile and cost-effective synthesis methods are employed to achieve novel nanomaterials and nanocomposites with well-defined structure for applications as high-performance cathodes and anodes in next-generation rechargeable batteries with significantly enhanced capacity, cycleability and rate capability. Another category of the work is focused on dye-sensitized solar cell (DSSC) which is considered as one of the most promising photovoltaic devices in converting solar energy directly into electric energy, due to its low cost, easy fabrication method and eco-friendly nature. As a critical component of DSSCs, counter electrode catalyzes the reduction of I3-/I- and conducts electrons from the external circuit to the cell. Sulfides based counter electrodes are synthesized to replace traditional expensive platinum counter electrodes in DSSCs. The structure, morphology, and composition of these nanomaterials and nanocomposites are optimized to maximize the performance of the new electrodes in batteries or solar cells, and are systematically studied for fundamental understanding of the processing-structure-properties relationships.

报告人简介:Ying Wang is an associate professor in the Department of Mechanical & Industrial Engineering at Louisiana State University (LSU) in USA. Before joining LSU in 2008, she was a postdoctoral fellow in materials science at Northwestern University for two years. She obtained her Ph.D. in materials science and engineering from University of Washington in 2006, M. A. in chemistry from Harvard University and B. S. in chemical physics from University of Science and Technology of China. Her research interests center on the developments of novel nanomaterials and nanocomposites for energy and environmental applications, such as advanced batteries, solar cells and photocatalysis.
