Electrodeposition of Thin Gold Films from an Aminosilicate Stabilized Gold Sol

Abstract
Anodic deposition of thin films of gold nanodispersion from aminosilicate stabilized gold sols is demonstrated for indium‐tin oxide and platinum substrates. The films are conductive, semitransparent, and comprised of gold particles each coated by a thin aminosilicate shell. Anodic deposition of stabilized gold nanoparticles is a new way to produce modified electrodes comprised of silicate‐noble metal composite coatings with a high degree of interconnectivity between the gold grains. ©1999 The Electrochemical Society
