Electrodeposition of Pt nanoclusters on the surface modified by monolayer poly(amidoamine) dendrimer film

Preparation of Pt nanoclusters on the poly(amidoamine) (PAMAM) modified surface by electrodeposition was firstly reported. The presence of PAMAM could affect the growth of Pt nanostructures. Field-emitted scanning microscopy images showed that these nanoclusters were not common nanoparticles but were consisted of many small nanoparticles. The size of them could be controlled and the deposition mechanism was also discussed. This method would give a route of preparing novel nanostructures by electrodeposition. (c) 2005 Elsevier B.V.
