“Green" approach for self-assembly of platinum nanoparticles into nanowires in aqueous glucose solutions
A completely "green" synthetic approach has been developed for the reduction and stabilization of Pt nanoparticles followed by self-assembly into nanowires in an aqueous alpha-D-glucose solution. Hydrothermal treatment initiated the reduction of Pt(IV) ions dispersed in a pH 8.0 alpha-D-glucose solution in. Reduced Pt nanoparticles were stabilized with oxidized glucose molecules. The Pt nanoparticles continued growing into nanowires followed by transformation into cubic nanocrystals with a rough needle surface. Evidence from TEM and FT-IR spectra reveal that carboxylate groups, which are generated by the oxidation of alpha-D-glucose, strongly interact with and stabilize the surface of these Pt nanostructures.
