        Mono Mn(II)-substituted phosphotungstate@modified graphene oxide as a high-performance nanocatalyst for oxidative demercaptanization of gasoline

        Mohammad Ali Rezvani,Zahra Shokri Aghbolagh,Hassan Hosseini Monfared,Sahar Khandan 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.52 No.-

        In this study, the removal of hazardous sulfur compounds from gasoline was provided based on catalyticoxidation demercaptanization technique. The cesium salt of mono Mn(II)-substituted Keggin-typepolyoxometalate Cs5PMnW11O39 (PMnW11) was successfully synthesized and immobilized on modifiedgraphene oxide (mGO) as a new nanocatalyst (PMnW11@mGO) for demercaptanization process. Thesynthesized materials were characterized by powder X-ray diffraction (XRD), scanning electronmicroscopy (SEM), ultraviolet–visible (UV–vis), Fourier transform infrared spectroscopy (FT-IR), andcyclic voltammetry (CV) analysis. Characterization of the prepared nanocomposite was confirmed thatthe structures of the PMnW11 and mGO were retained after immobilization. The sulfur-containingmolecules in real gasoline and simulated fuel were oxidized and extracted efficiently under mild reactioncondition. After treatment, the mercaptans and total sulfur content of real gasoline were lowered with98.8% and 98% yield, respectively. The PMnW11@mGO hybrid nanocatalyst was separated and reusedconveniently at the end of the reaction forfive times. The excellent performance of this new catalyticoxidation system can be a promising rout to achieve ultra-clean gasoline.
