In this presentation, we have carried out systematic studies on the synthesis and stabilization of silver nanoplates. By harnessing the oxidative power of H2O2, various silver sources including silver salts and metallic silver can be directly converted to nanoplates with the assistance of an appropriate capping ligand, thus significantly enhancing the reproducibility of the synthesis. Contrary to the previous conclusion that citrate is the key component, we have determined that the group of ligands with selective adhesion to Ag (111) facets can be expanded to many di- and tri-carboxylate compounds whose two nearest carboxylate groups are separated by two or three carbon atoms. The improved insight into the specific roles of the reaction components and significantly enhanced reproducibility are expected to help elucidate the formation mechanism of this interesting nanostructure.
