Hyperbranched polyamidoamine as stabilizer for catalytically active nanoparticles in water

Poly(amidoamine) hyperbranched polymers (HYPAM) were Successfully used to synthesize platinum nanoparticles of ca. 1.8 nm and to stabilize these particles in water. Furthermore these hyperbranched-stabilized platinum nanoparticles proved to be effective and robust for hydrogenation reaction in water. (C) 2008 Elsevier Inc. All rights reserved.
