Synthesis and characterization of new organic-inorganic hybrid [C16H33N(CH3)3]7H3[P2W18Mn4O68]-TiO2 composite as an efficient nanocatalyst for oxidative desulphurization of gas oil

The oxidative desulphurization of gas oil and model fuel has been studied using [C16H33N(CH3)3]7H3[P2W18Mn4O68]-TiO2 as a new nanocatalyst. The nanocatalyst was synthesized by an unusual reaction with titanium tetraisopropoxide at 100 ºC via sol–gel method under oil-bath condition. The materials characterized by 31P NMR, XRD, FTIR and UV–vis techniques. The prepared composite was shown to be able to scavenge hydrogen sulphide and mercaptans in high yields. The addition of hydrogen peroxide/acetic acid enhanced the conversion. This system provides an efficient, convenient and practical method for scavenging sulphur compounds.
