Preparation of nanoparticle catalysts becomes more and more sophisticated in order to meet the increasingly stringent structural requirements for advanced performance in high activity and selectivity.  New approaches have been developed in recent years in the control of nanocrystal size, facet,composition and various core-shell structures in order to tackle the challenges.  Such research endeavors result in a new push for better quantitative understanding of nucleation and growth kinetics insolution.  In this talk, I will focus on ourrecent work in the following topical areas: 1) the solution processing of metalnanoparticles, especially the production of uniform, facet-defined catalystsusing carbon monoxide as a processing gas. The formation of shape- and composition-controlled multimetallic nanostructures will be discussed, including alloys in their so-called immiscibility regime of their bulkcounterparts; 2) theoretical and experimental understanding of ligand chemistryin the design and controlled synthesis of metal catalysts; 3) in situ liquid flow cell technology for transmission electron microscopy technique in the understanding of nucleationand growth of heterogeneous nanoparticle catalysts; 4) in situ, variabl etemperature environmental TEM (ETEM) study of structural behavior of catalyst under reactive conditions; and 5) structure and property relationship of catalysts for the electrochemical reduction of oxygen and other reactions.
