Abstract

A study is conducted to demonstrate how layered nanocomposite of close-packed gold nanoparticles and TiO2 gel layers. The study demonstrates the preparation of alternate layers of ultrathin TiO2 films and modified gold nanoparticles. The modified gold nanoparticle possesses surface hydroxyl groups, and they behave as an active component in the surface sol-gel process. Nanocomposites obtained from these components will be composed of high concentrations of nanoparticles in metal oxide thin films. Gold nanoparticles are prepared by reduction of HAuCl4 by NaBH4 in methanol/acetic acid in the presence of (SC11OH)2. Each particle had a spherical shape of a uniform size.
