(Bu4N)(4)H[PMo10V2O40]-TiO2 nanocomposite has been synthesized by a reaction of (Bu4N)(4)H[PMo10V2O40] with titanium tetraisopropoxide at 100 degrees C via the sol gel method. The crushed nano layer of the anatase phase was 20 nm in nature and the fixing of (Bu4N)(4)H[PMo10V2O40] decreased its size. This nano polyphosphomolybdate was shown to be able to oxidatively desulphurize simulated gas oil with a high S conversion (more than 98 %). In the present work, the efficient oxidative desulphurization of gas oil and simulated gas oil using the formic acid/hydrogen peroxide system is reported. This system provides an efficient, convenient and practical method for scavenging sulfur compound.
