Abstract:
This note mainly reports a successful preparation of a alumina-pillared layered titanate with a high interlayer spacing through a step-wise exchange process. X-ray diffeaction patterns indicate that the resultant alumina-pillared layered titanate has an interlayer spacing of 1.70 nm, which is 0.17 nm higher than that of previously reported,and has a thermal stability over 500 ℃. The surface area (N2, BET method) of the product is determined to be 72.4 m2·g-1. The N2 adsorption and desorption isotherm of the product demonstrates that the resultant alumina-pillared layered titanate is porous, with both micropores and mesopores.
