Fabrication and characterization of novel Polymer/MetalOxide/Polyoxometalate(PMP) Compositeand its highly catalytic performance for the oxidative desulfurization

With the increasing aim of deep desulfurization of fuel, a kind of novel Polymer/Metal Oxide/Polyoxometalate (PMP) composite was successfully synthesized. This catalyst was exploited to act as a stable heteropolyacid-based one, under the dual protection functions of polyaniline and lead oxide. Structure was characterized by Fourier transform infrared (FT-IR) and scanning electron microscopy (UV-Vis). Our contribution demonstrates a new way of fuel desulfurization, namely selective oxidation of organic sulfur(S)-compounds present in fuels to water-soluble sulfur compounds followed by in-situ extraction of the latter into an aqueous phase.The results of oxidative desulfurization (ODS) revealed that PMP composite was an excellent catalyst capable of removing more than 90% of sulfure content compounds to less than 10 ppmw, after 60 minutes.
