Abstract

Anodic deposition of thin films (up to 0.5 μm thick) 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 4-6 nm 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.
