Metal nanoparticles are the central player in heterogeneous catalysis. The recent success in creating atomically precise nanoparticles (or nanoclusters) and solving their total structures have offered exciting opportunities for understanding some fundamental issues that were previously difficult to tackle with polydisperse nanoparticles. The X-ray crystallographic structures of nanoclusters offer unprecedented insights into the structure-property relationships at the single-atom level. This talk will present some progress in utilizing atomically precise gold and bimetallic nanoclusters for catalytic research, including the effects of nanocluster size, atomic structure, charge states, and bimetallic synergy at the atomic level. The obtained information will facilitate fundamental understanding of catalytic mechanisms and the design of highly efficient catalysts for certain reactions. The pursuit of atomic-level tailoring will open up new opportunities for controlling nanoparticle catalysts on an atom-by-atom basis.
