title: In Situ Synthesis of Highly Dispersed and Ultrafine Metal Nanoparticles from Chalcogels.
abstract: We report a unique reaction type for facile synthesis of ultrafine and well-dispersed Pt nanoparticles supported on chalcogel surfaces. The nanoparticles are obtained by in situ Pt2+reduction of a chalcogel network formed by the metathesis reaction between K2PtCl4and Na4SnS4. The rapid catalytic ability of the chalcogel-supported Pt nanoparticles is demonstrated in a recyclable manner by using 4-nitrophenol reduction as a probe reaction.
