In this manuscript, a novel nanocomposite PMo 11 CdO 39 @MnFe 2 O 4 (PMo 11 Cd@MnFe 2 O 4 ) based on ceramic (MnFe 2 O 4 ) and mono substitute polyoxometalate (PMo 11 Cd) was synthesized successfully via sol–gel method in extremely mild conditions. PMo 11 Cd@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 H 2 O 2 /CH 3 COOH 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 PMo 11 Cd@MnFe 2 O 4 nanocatalyst attained via 0.1 g of dosage and H 2 O 2 /CH 3 COOH as oxidation system. The process obeyed the pseudo‐first‐order kinetics as the correlation factor was close to unity. In the end, the PMo 11 Cd@MnFe 2 O 4 demonstrated good reusability after 5 runs.
