Preparation of TiO2-pillared montmorillonite; degradation of methylene blue by photocatalyst

In this study TiO2-pillared montmorillonite was prepared using TiCl4 hydrolysis to form TiO2 particles into the interlayer space of montmorillonite. The structural analysis of the pillaredmontmorillonite were determined by X-ray diffraction (XRD), and BET method. Then degradation of methylene blue was carried out with TiO2- montmorillonite in aqueous solution under UV irradiation. TiO2-montmorillonite had high photocatalytic activity because of its high specific surface area caused by pillaring and loading of TiO2 for photooxidation
