Abstract

Rutile TiO2 with high specific surface area was synthesized by self-hydrolysis of TiOCl2 in the presence of sodium dodecyl sulfate (SDS). The aggregates of rutile acicular particles formed from 0.5 M TiOCl 2 at 50°C. In order to synthesize rutile with high specific surface area, the effect of surfactant was investigated. Three kinds of surfactants were used in this study, such as stearyltrimethylammmonium chloride (C18TAC) as cationic surfactant, polyoxyethylene lauryl ether (Brij3(5) as nonionic surfactant, and SDS as anionic surfactant. Neither C18TAC nor Brij35 was influenced on the morphology of rutile particles. On the other hand, the addition of SDS was effective for the formation of mesopore, which led to specific surface area of 210 m2/g in product.
