We present a systematic study of ligand-mediated nanocluster (NC) formation using kinetic model, which provides atomic insight into sub-nanometer cluster (S-NC) and NC formation. Our model describes the role nucleation growth in obtaining monodisperse NCs. Nucleation includes metal ion reduction, reversible ligand association to ion/atom, dimer nuclei. Growth can occur through autocatalytic surface ligand-associated monomer addition cluster, depending on rate neutral atom conversion. Furthermore, we studied effect initial concentration ions fast slow reducing agents presence slowly rapidly binding ligands. The shows that nucleation, growth, high molar ratio promote S-NCs results guide experiments synthesis ultrasmall clusters.
