Synthesis and characterization of titania pillared montmorillonites
Written by sctunisie no commentsTitania pillared montmorillonite was prepared by the reaction of Na-Montmorillonite with polymeric Ti cations, formed by partial hydrolysis of TiCl4 in HCl. The resulting TiO2-cross-linked montmorillonite has a surface area of 316 m2/g and pore volume of about 0.17 cm3/g and is thermally stable up to 500°C. The pillar heights of the product heated at a temperature > 100°C was 17-15 Å. The uptake of TiO2 by the montmorillonite depends on the ratio H+/Ti in the solution.
