摘要：

TiO2 photocatalysts film supported on glass plate was soaked in a pseudo body solution (PBS) containing excess phosphate ions. The surfaces were characterized by scanning electron microscopy, energy-dispersive spectroscopy, thin-film X-ray diffraction, and Fourier-transformed infrared methods. After soaking in the pseudo body solution for 1 day, a bone-like apatite layer was formed on the surface of the TiO2. The apatite layer was approximately 0.7 mm thick and made up of thin plate-like crystals. The haze values of dry and wet specimens were 28.47 and 9.51%, respectively. The apatite-coated TiO2 thin film could be used for antibacterial and environmental purification purposes. (C) 1998 Elsevier Science Ltd.
