Abstract: Silica-pillared layered titanate was first prepared by using a new method proposed in this paper.It entails first intercalating H2Ti4O9 with n-hexylamine and then the reaction of the intercalated titanate with APSaqueous solution, and finally calcinating the reaction product in air sequently.The resultant silica-pillared layered titanate has a high surface area of 137.9 m2/g (550℃) and good thermal stability above 550℃.The N2 adsorption-desorption isotherm of this new material demonstrates that it is porous, with an average pore diameter of 3.5 nm.
