Academic Lecture Composition and Surface Controlled High-Performance Catalysts 报告人：黄 昱 教授 (UCLA, USA） 时 间： (周四)下午 14:30-16:00 地 点：图书馆一层多功能厅 报告简介： Noble metal-based nanocrystals have played important roles in heterogeneous catalysts due to their high activity and chemical stability. The high cost of noble metals, however, created roadblocks for the large volume production of noble metal catalysts for many applications. Improving the catalytic activity or the efficiency of noble metal usage, and prolong the life-time of a noble metal based catalysts are solutions to these challenges. On a nanocatalyst, the composition, atomic coordination, and strains of the top surface layers eventually determine its performance in catalytic reactions. Slight changes in the surface structure of catalytic materials, such as increase in the number of accessible surface adsorption sites or generating uniform surfaces with abundant specific defects, can have large impacts on the catalytic stability and activity. In this presentation I will share our recent efforts on tuning the surface compositions and structures of noble metal catalysts to improve both catalytic activity and stability. 报告人简介: Professor Huang receives her Ph.D in physical chemistry from Harvard University and her B.S. in chemistry from University of Science and Technology of China. In 2015, she was promoted to full professor. Focusing on the molecular level, she conducts research to unravel the fundamental principles governing nanoscale material synthesis and assembly; and utilizes such principles to design nanostructures and nanodevices with unique functions and properties to address critical challenges in electronics, energy science and biomedicine. Recognitions she received include the World’s Top 100 Young Innovators, the Sloan Fellowship, the PECASE, DARPA Young Faculty Award and the NIH New Innovator Award. 黄昱教授主要从事纳米科学领域的研究，近年来，在纳米催化剂的制备及其催化性能调控方向有许多重大发现，在Nature、Science等顶尖学术刊物发表多篇论文；还因太阳能光解水项目重大研究成果而获得2009年度美国“青年科学家与工程师总统奖”。 部分代表作： 1.
