Abstract

(Bu4N)7H3[P2W18Cd4(Br)2O68]–TiO2 nanocomposite have been synthesized first by reaction of A-β-Na8HPW9O34 with cadmium nitrate and next condensation with titanium tetraisopropoxide at 100 °C via sol–gel method under oil-bath condition. The materials characterized by 113Cd NMR, 31P NMR, XRD, TEM and UV–vis techniques. The crushed nano leaf of anatase phase is 20 nm in nature and fixing of (Bu4N)7H3[P2W18Cd4(Br)2O68] decreases its size. As seen in TEM image, the nano particles of (Bu4N)7H3[P2W18Cd4(Br)2O68]–TiO2 are small with a size of about 10 nm. This anatase nanocomposite polyoxometalate was shown be able to oxidative desulfurization of simulated gas oil with high yield.
