Titanium-pillared inter-layered clays (TiPILCs) were prepared by intercalating polymeric cationic species in clay layers. The intercalation was obtained by hydrolysis of TiCl, with HCl (TiPILC-Cl) and HISO, (TiPILC-S). The influence of the determinant parameters viz. the H+/Ti and Ti/clay ratios, wa
SiO 2 -ZrO 2 pillared montmorillonite (SZM) was prepared by the reaction of Na-montmorillonite with colloidal silica-zirconia particles which were prepared by depositing zirconium hydroxy cations on silica particles. By pillaring with the colloidal particles, the basal spacing of montmorillonite was
