Preparation and Characterization of Silica-Alumina-Pillared Rectorites

Abstract:

The silica-alumina-pillared rectorite materials (SiAl-REC) were developed a novel method, which combined several techniques such as ion-exchange, intercalation and surfactant modification. The morphology, composite structure and pore properties of such composite materials, were investigated by X-ray powder diffraction (XRD), Fourier-transform infra-red (FTIR) spectra, as well as Nitrogen Adsorption-Desorption Isotherms. The layer structure of the prepared materials retained and their pore structures were found to be slit-shaped pores located between plate-like particles. The prepared SiAl-REC materials had a BJH pore volume of 0.65cm³ g-1, a remarkably high BET specific surface area940m² g^-1 and a narrow pore size distribution in the mesoporous region 4.3 nm after thermal treatment at 600 °C.
