A smart hybrid system of Au nanoparticle immobilized PDMAEMA brushes for thermally adjustable catalysis†
Abstract
A smart hybrid system was prepared by introducing the temperature responsive PDMAEMA brushes and Au NPs into silica NPs through self-initiated photografting and photopolymerization (SIPGP) and reduction of HAuCl4. The obtained SiO2@PDMAEMA–Au hybrid system was investigated to have a thermally adjustable catalytic activity for the reduction of 4-nitrophenol.
