Abstract

Colloidal suspension of titanate nanosheets has been prepared by exfoliation of Cs_0.67-Ti_1.83O₄ through the intercalation of tetrabutylammonium (TBA). The atomic scale structure of the nanosheets has been determined using X-ray diffraction and the atomic pair distribution function (PDF) technique. The exfoliated titanate nanosheets have been found to be an irregular assembly of double layers of Ti-O₆ octahedra accommodating water and TBA molecules in the interlayer space. The interlayer distances show a wide distribution ranging from 9 to at least 18 Å. The separation between the titanate layers remains nearly the same in air-dried product of the colloidal suspension.
