Photocatalytic nanocomposite thin films of TiO2-β-calcium phosphate by aerosol-deposition

3–0 type of TiO2-β-TCP photocatalytic nanocomposite thin films were fabricated by aerosol-deposition. The fabricated films consisted of nano-sized, TiO2 photocatalytic crystallites with a dispersion of β-TCP adsorbent crystalline phase. The nanocomposite films showed strong photocatalytic activities such as degradation of methylene blue aqueous solution and bactericidal effect under both UV and dark conditions due to the adsorption effect of β-TCP.
