Abstract
Titania pillared H4Nb6O17 has been synthesised by the intercalation of [Ti( OH)(x)(CH3CO2)(y)](z+) followed by photodecomposition with UV light irradia tion. The incorporation of TiO2 in the interlayer of H4Nb6O17 has been conf irmed by powder X-ray diffraction, DTA, UV-VIS reflectance and BET measurem ents: The incorporation of TiO2 in the interlayer of H4Nb6O17 results in en hanced water cleavage by band gap irradiation. The photocatalytic activity of TiO2 pillared H4Nb6O17 prepared using [Ti(OH)(x)(CH3CO2)(y)](z+) was hig her than that of a sample prepared using a TiO2 sol solution.
