The pursuit of well-defined nanoparticles has attracted much attention in recent research. The attainment of atomically precise nanoparticles is of major importance for both fundamental studies and development of applications. This talk will present the synthesis and catalytic application of size-specific Aun(SR)m nanoparticles with n ranging from a few dozens to several hundreds of atoms (often called nanoclusters). Such ultrasmall nanoparticles exhibit distinct quantum size effects and interesting electronic and optical properties, which are fundamentally different from their larger counterparts � plasmonic nanoparticles. New types of atom-packing structures have been discovered in Aun(SR)m nanoclusters. The catalytic properties of nanoclusters can be truly tuned on an atom-by-atom basis. Correlation of the catalytic properties with structures will ultimately offer fundamental understanding on nanogold catalysis.
