Polymer microcapsules loaded with Ag nanocatalyst as active microreactors

Abstract

Silica-supported silver nanoparticles (Ag/SiO₂) encapsulated inside the PNIPAM-based microcapsules (MC) were proved to be an efficient and easy-to-handle catalyst. Due to the hydrophilic nature of MCs, they act as microreactors in a mixed organic–aqueous environment. It was demonstrated that the catalytic activity of encapsulated Ag/SiO₂ substantially exceeds that of freely dispersed catalyst.
