Abstract
TiO2 pillared mica was prepared using Ti ion species as TiO2 precursor. The titanium ion species were obtained by an addition of several titanium alkoxides to an aqueous solution of CH3COOH, with different CH3COOH/Ti ratios and temperatures. The structure and properties of the TiO2 pillared mica was studied by X-ray diffraction, N2 adsorption, FT-IR and TG-DTA. After calcined at 500°C, the BET surface area of samples varied between 250 and 460 m2/g. The sample prepared using titanium tetraethoxide as titanium source possessed well ordered structure and higher BET surface area. The basal spacing of TiO2 pillared mica was increased with the decrease in CH3COOH/Ti ratio and the increase in temperature of preparation of titanium ion species, while the degree of ordered structure of pillared mica was decreased.
