Optimal design of nanostructure is essential to achieve the requirements of catalytic performance in activity and stability. In this context, catalysts produced through conventional impregnation method can be further treated to create the catalytic surface with controlled single atom position or sub-monolayer atoms. In this talk, I will use AgPt bimetallic as an example to present our latest understandings on the design and post-synthesis treatment of bimetallic catalysts to address the processing challenges in size, facet, surface composition and structures (e.g., site specific bimetallic catalysts). The focus of this presentation will be on the controlled synthesis of bimetallic structures in solution, in situ variable temperature environmental transmission electron microscopy (TEM) in studying the structural dynamics of bimetallic catalysts, structure-property relationship, and density functional theory (DFT) calculation in understanding the new catalytic phenomena [1-4].
