Abstract

TiO2-coated hydroxyapatite single crystals were prepared by hydrolysis of Ti-bearing dicalcium phosphate powder. On the surface of the TiO2-coated hydroxyapatite single crystals, TiO2 regions and hydroxyapatite regions can function as photocatalysts and adsorbents for organic contaminants, respectively, allowing simultaneous decomposition of organic contaminants by the photocatalysis of TiO2 under irradiation. Therefore, the TiO2-coated hydroxyapatite single crystals can favorably be applied for antibacterial applications and environmental purification.
