A Novel Method for the Synthesis of Mesoporous TiO₂ at Ambient Temperature

Abstract

Using anionic surfactant sodium alkyl epoxy ethylene carboxylate as structure-oriented agent mesoporous titanium dioxide was direct prepared at ambient temperature via hydrolysis precipitation. The synthesized products were characterized by XRD and N2-adsorption. XRD analysis indicates that the TiO2 exhibits anatase phase and its pore disappears at 550 °C calcinations temperature. N2-adsorption results shows that high surface area of 324 m2/g, pore volume of 0.211 cm3/g and pore size of 3.5 nm were obtained in no heat-treated sample.
