主持人:徐宇曦博士,新葡萄京娱乐场工学院PI

Host: Yuxi Xu, Ph.D., PI of School of Engineering

 

 主讲人/Speaker:Yu Huang Ph.D., Professor of Department of Materials Science and Engineering, University of California, Los Angeles (UCLA)


Prof. Huang received her B.S. in Chemistry from University of Science and Technology of China (USTC), and her Ph.D. in physical chemistry and M.A in Chemistry from Harvard University. Before she embarked on her independent career at UCLA She was awarded the prestigious Lawrence Fellowship and held a joint postdoctoral position with Lawrence Livermore National Lab (LLNL) and Massachusetts Institute of Technology (MIT).


Her research focuses on mechanistic understanding of nanoscale phenomena and on exploiting the unique properties of nanoscale materials for various applications. Taking advantage of the unique roles of nanoscale surfaces and interfaces, Prof. Huang is creating methodologies to apply the latest developments in nanoscale materials and nanotechnology for probing nanoscale processes that can fundamentally impact a wide range of technologies including materials synthesis, catalysis, fuel cells, and devices applications. Prof. Huang’s achievements have gained her international and national recognitions including the Materials Research Society (MRS) Fellow, the Royal Society of Chemistry (RSC) Fellow, the International Precious Metal Institute (IPMI) Carol Tyler Award, the Presidential Early Career Award in Science and Engineering (PECASE), the National Institute of Health (NIH) Director’s New Innovator Award, the Defense Advanced Research Projects Agency (DARPA) Young Faculty Award, the World’s Top 100 Young Innovators award, the Sloan Fellowship, the International Union of Pure and Applied Chemistry (IUPAC) Young Chemist Award, and the Nano 50 Award.

 

讲座摘要/Abstract:

Noble metal-based nanocrystals have played important roles in heterogeneous catalysis due to their high activity and chemical stability. Owing to the large surface to volume ratio at nanoscale slight changes in the surface structure of catalytic materials can have large impacts on the catalytic stability and activity. The composition, facet, and the topology of the top surface layers of a nanocatalyst eventually determine its performance in catalytic reactions. In this presentation, I will share our recent efforts on designing the surface compositions, structures and the overall morphology of noble metal catalysts to improve both catalytic activity and stability of nanocatalysts.
