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.
