摘 要: Organically capped metal nanoparticles represent a unique class of functional nanomaterials. Traditionally the material properties can be manipulated by the chemical nature of the organic ligands as well as the metal cores. Recently we found that the metal-ligand interfacial bonding interactions may also play a significant role in controlling the nanoparticle optical and electronic properties. In this presentation we will discuss several examples of transition-metal nanoparticles functionalized by various metal-ligand covalent bonds including metal-carbon and –nitrene bonds where extensive intraparticle charge delocalization occurs, and highlight the impacts of such unique interfacial interactions on the nanoparticle electrochemical and photoluminescence properties, and in particular, on nanoparticle catalysis for fuel cell electrochemistry.
主讲人简介: Shaowei Chen finished his undergraduate studies in China in 1991 with a BS degree in Chemistry from the University of Science and Technology of China, and then went to Cornell University receiving his MS and PhD degrees in 1993 and 1996 respectively. Following a postdoctoral appointment in the University of North Carolina at Chapel Hill, he started his independent career in Southern Illinois University in 1998. In summer 2004, he moved to the University of California at Santa Cruz. He is currently a Professor of Chemistry. http://chen.chemistry.ucsc.edu/schen.htm
