Abstract

Titanium alkoxides were prepared by anodic dissolution of metallic titanium in absolute ethanol in the presence of HN(C₂H₅)₂·HCl (electro-conductive additives). The solution was directly hydrolyzed to prepare nanocrystalline of TiO₂ (about 10nm)by a sol-gel process. The precursor gels was calcined at T =450 ℃ and 720 ℃ for 30 min, and nanocrystalline of TiO₂ (anatase) with high textural and thermal stability was obtained. FTIR, XRD, TEM were used to characterize the structure of titanium alkoxides and nanocrystalline of TiO₂. The characteristics of nanocrystalline of TiO₂ was depended on the properties of titanium alkoxides. The Ti(OEt)₄ as a source of titanium yielded the best textural and thermal stability nanocrystalline of TiO₂.
