Methylviologen mediated electrochemical reduction of AgCl - A new route to produce a silica core/Ag shell nanocomposite material in solution

Abstract

© 2015 Elsevier B.V. All rights reserved. Methylviologen mediated electrochemical reduction of AgCl precipitate to Ag⁰ in the presence of alkylamino-modified silica nanoparticles (SiO<inf>2</inf>-NHR) in an aqueous medium was performed. The main products of reduction at potentials of the MV^{2 +}/MV^•+ redox couple are spherical SiO<inf>2</inf>-NHR/Ag core/shell nanoparticles (size range 120-160 nm) in solution.
