Abstract

Abstract : Catalytically active polymer-grafted gold nanoflowers are prepared by combining ARGET ATRP and metal reduction in a one pot reaction. Abstract : We report a convenient strategy for the synthesis of polymer-grafted gold nanoflowers by combining an activator regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP) and the reduction of metal ions in a one-pot fashion. Poly( N -isopropylacrylamide)-coated gold nanoflowers (PNIPAM-AuNFs) with controllable sizes, shapes, and shell thickness are obtained and applied as temperature-controlled nanoparticle catalysts for the hydrogenation of p -nitrophenol.
