Noble metal-based nanocrystals have played important roles in heterogeneous catalysis due to their high activity and chemical stability. Owing to the large surface to volume ratio at nanoscale slight changes in the surface structure of catalytic materials can have large impacts on the catalytic stability and activity. The composition, facet, and the topology of the top surface layers of a nanocatalyst eventually determine its performance in catalytic reactions. In this presentation, I will share our recent efforts on designing surface compositions, structures and the overall morphology of metal catalysts to improve both catalytic activity and stability of nanocatalysts, as well as the studies to understand such effects.
