Abstract:Preparation of precisely controlled metal and its alloy nanoparticles becomes an important research area in order to meet the increasingly stringent structural requirements for advanced performance, such as catalysts and electrocatalysts with high activity, stability and selectivity. New approaches have been developed in recent years to meet these challenges. At the same time, such endeavors also result in a major push for better fundamental understanding of nucleation and growth in non-aqueous solutions. In this talk, I will present our work in the following topical areas: 1) recent advances in the solution processing of nanoparticles, especially metal nano-miscibility, CO-based gas reducing agent in liquid solution method for the preparation of shape- and composition-controlled multimetallic nanostructures; 2) the production of uniform nanocrystals; 3) ligand chemistry in the design and controlled synthesis of metallic nanostructures; 4) applications of nanoparticles as electrocatalysts for oxygen reduction and evolution reactions, and 5) non-PGM electrocatalysts. The use of density functional theory in understanding the growth will also be discussed.

Bio:Prof. Hong Yang received his B.Sc. degree from Tsinghua University (1989), M.Sc. degree from University of Victoria (1994), and Ph.D. degree from University of Toronto (1998). He received the NSERC Canada Doctoral Prize, the highest graduate student prize in Canada for the Ph.D. thesis work carried out in any Canadian universities. After working at Harvard University as an NSERC postdoctoral fellow, he started his independent research and rose through the academic ranks at University of Rochester before joining the faculty of University of Illinois at Urbana-Champaign as a Professor of Chemical and Biomolecular Engineering in 2012. Dr. Yang is an NSF CAREER Award recipient. He is a Section Editor on Nanotechnology forCurrent Opinion in Chemical Engineering(Elsevier) and serves on the Editorial Boards ofNano Today(Elsevier),ChemNanoMat(VCH),Science China Materials(Chinese Academy of Sciences), and other journals. His research interests include understanding the formation of nanocrystals, surface modification, catalysis,in situtechniques, and nanomaterials for energy and biological applications.
