In recent years, nanocomposite materials have been the subjects of intensive research due to their unique properties and numerous potential applications in heterogeneous catalysis, high-k dielectric materials, optical wave guides, paints, antibacterial agent, and fillers for thin paper. Manipulation of their sizes, shapes, microstructures, surface activity, and surface areas is crucial to improving their characteristic properties: catalytic activity, photoactivity, chemical durability, and their optical and thermal properties. The properties of final product strongly depend on the properties...
