Ultra-deep desulfurization of gasoline through mono Mn(II)-substituted phosphotungstate@CuO@PANi as a high-performance nanocatalyst

This paper describes the oxidation of several sulfur containing molecules with hydrogen peroxide in a two liquid–liquid (L–L) phase system with a phase transfer catalyst under atmospheric pressure. Polyoxometalates with favorable oxidation potentials and reactive transition metal centers are useful for electron transfer oxidation reactions. So, the oxygenation of sulfides to the corresponding sulfoxides catalyzed by a novel lacunary polyoxometalate, under the dual protection functions of polyaniline and cuper oxide. The material (PW11Mn@CuO@PANi) was characterized by FT-IR and UV-Vis spectroscopy. Catalytic activity of synthesized nanocomposite was tested on oxidative desulphurization of actual gasoline. The advantages of this method lie in its mild condition, low cost, large scale, simplicity and environmentally friendly route.
