Abstract

Crown-shaped platinum nanoparticles were synthesized by UV irradiation in the presence of G4-NH2 PAMAM dendrimers in water. Aggregates of the dendrimers, which were formed in the aqueous solution, served as templates for the formation of such nonspherical nanoparticles. This is the first report on the preparation of structure-controlled platinum nanoparticles by photoreduction. This methodology to use dendrimer aggregates as templates is powerful for the production of shape-controlled nanostructures.
