Preparation of Nano-TiO₂ Modified by Ionic Liquid and its Photocatalytic Activity

Abstract:

Nano-TiO₂ modified by ionic liquid was prepared by sol-gel method with Ti(OC₄H₉)₄ as titanium source. The chemical structure of the nanopartical was characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and UV-Vis diffuse reflectance spectra (UV-Vis DRS). The results indicated that the modified TiO₂ was almost entirely small nanocrystal and multihole and had high crystallinity. Radius of the modified particals had some degeree of reduction than that of the pure TiO₂. The optical absorptivity of modified TiO₂ is stronger than that of unmodified TiO₂. The photocatalytic degradation activity of methylene blue with the prepared TiO₂ was investigated. The degradation rate could reach more than 88%.
