锐钛矿型TiO2薄膜的低温制备及其光催化性能研究
Low-temperature preparation and photocatalytic performance of anatase TiO2 thin films
摘要
Abstract
Nano-TiO2 thin films were prepared at low temperature by an improved sol-gel method and dip-coating technique. The phase and crystal structure, surface morphology and optical absorption properties of the prepared TiO2 films were characterized by X-ray diffractometer (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscope (SEM) and ultraviolet-visible spectrometer (UV-Vis), respectively. The photocatalytic activity of the TiO2 films was evaluated through degrading the methylene blue solution under UV radiation. The results show that the Nano-TiO2 thin films prepared at low temperature possess an anatase structure and a uniform dense surface, and show a strong UV absorption. With the Nano-TiO2 films as the photocatalyst, 67.4% of the methylene blue solution is degraded after exposure to UV radiation for 48 h.关键词
