Synthesis of new nanocomposite based on nanoceramic andmonosubstituted polyoxometalate, PMo11Cd@MnFe2O4, with superior catalytic activity for oxidative desulfurization of real fuel

In this manuscript, a novel nanocomposite PMo11CdO39@MnFe2O4(PMo11Cd@MnFe2O4) based on ceramic (MnFe2O4) and mono substitute polyoxometalate (PMo11Cd) was synthesized successfullyviasol-gel method in extremely mild conditions. PMo11Cd@MnFe(2)O(4)has been proposed as a new heterogeneous inorganic nanocatalyst for highly efficient deep desulfurization of model fuel/real gasoline. The successful synthesis of as-prepared compounds was proved by FT-IR, XRD, SEM, and EDX techniques. The catalytic oxidative desulfurization (CODS) was performed under mild conditions in the presence of 50 ml of model fuel/real gasoline, 3 ml of oxidant with 2:1 H2O2/CH3COOH volume ratio. The efficiency was further detailed by pursuing different effective properties on the CODS process like dosage effects, different oxidation system and different catalyst effects. The best results of PMo11Cd@MnFe(2)O(4)nanocatalyst attainedvia0.1 g of dosage and H2O2/CH3COOH as oxidation system. The process obeyed the pseudo-first-order kinetics as the correlation factor was close to unity. In the end, the PMo11Cd@MnFe(2)O(4)demonstrated good reusability after 5 runs.
