Abstract

Abstract: Using Gemini231 quaternary ammonium salts cationic surfactant as template, mesoporous titanium dioxide material was synthesized by sol-gel method at room temperature. The synthesized samples were investigated by thermogravimetic-differential thermal analysis, X-ray diffraction, nitrogen adsorption-desorption and transmission electron microscope(TEM) techniques. The results show that the obtained mesoporous TiO₂ calcined at 480℃ have a high specific surface area up to 383.8m^2_·g¹, and a mean pore size of about 5.8nm in diameter, and crystallized anatase framework. No rutile phase is found. Small-angle X-ray diffraction analysis shows that the sample has an ordered mesoporous structure.
