报告摘要：In this talk, I will present our recent research efforts on the development of functional nanomaterials for several energy-related applications and on a study of the physiochemical interactions between metal nanoparticles and biological media. In the first part of this presentation, our current focus is on the design and understanding the formation mechanism of metal and alloy nanostructured catalysts using new well-defined, molecular precursors and on the use of in situ transmission electron microscope (TEM) technique to understand the formation mechanism. By carefully selecting new precursors, we are able to achieve high-level controls over the synthesis of low dimensional solids, including two dimensional (2D) metal materials and other shaped control nanoparticles based on the density functional theory calculation analysis. Using in situ characterization technique, we are able to directly observe the growth of complex nanostructures in real time. Such data allows us to develop quantitatively the growth kinetics and thus new insights in the precision design of complex catalysts in solution phase. I will also discuss the use of non-carbon based supports for both noble metal containing and non-Pt based catalysts for reactions that involve oxygen-containing intermediates, such as reduction of oxygen and oxygen evolution reaction. In the second part, I will use copper nanoparticle as an example to illustrate how surface chemistry affects the reactive oxygen generation (ROS) capability, and the cytotoxicity based on the analysis of changes of various structural parameters.
