Synthesis and photocatalytic properties of titania pillared H4Nb6O17 using titanyl acylate precursor
Abstract
Titania pillared H

followed by photodecomposition with UV light irradiation. The incorporation of TiO

in the interlayer of H

has been confirmed by powder X-ray diffraction, DTA, UV-VIS reflectance and BET measurements. The incorporation of TiO

results in enhanced water cleavage by band gap irradiation. The photocatalytic activity of TiO
