In this work, a new nanocomposite (PMo11Cu@MgCu2O4@CS) was synthesized by reaction of copperII‐monosubstituted phosphomolybdate (PMo11Cu), magnesiocopperite (MgCu2O4) and Chitosan (CS) via the sol‐gel method. The assembled nanocomposite was characterized by FTIR, XRD, SEM. The catalytic activity of the nanocomposite was tested on oxidative desulfurization (ODS) of real gasoline in the presence of CH3COOH/H2O2 in the volume ratio of 1/2 as an oxidant. Additionally, the results were compared with the oxidation reaction of prepared model sulfur compounds at the same conditions. The ODS results showed that immobilized of PMo11Cu on the CS and MgCu2O4 nanoceramic increased the efficiency and activity of the PMo11Cu in the removal of organic sulfur compounds (OSCs). The PMo11Cu@CS @MgCu2O4 could be reused for at least five times without notable reduction in efficiency of ODS system. This investigation presents a promising approach to the efficient removal of OSCs from gasoline using PMo11Cu@MgCu2O4@CS catalyst under mild reaction conditions.
