Synthesis and Characterization of New Inorganic‐Organic Hybrid Nanocomposite PMo11Cu@MgCu2O4@CS as an Efficient Heterogeneous Nanocatalyst for ODS of Real Fuel

Abstract In this work, a new nanocomposite (PMo 11 Cu@MgCu 2 O 4 @CS) was synthesized by reaction of copper II ‐monosubstituted phosphomolybdate (PMo 11 Cu), magnesiocopperite (MgCu 2 O 4 ) 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 CH 3 COOH/H 2 O 2 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 PMo 11 Cu on the CS and MgCu 2 O 4 nanoceramic increased the efficiency and activity of the PMo 11 Cu in the removal of organic sulfur compounds (OSCs). The PMo 11 Cu@CS @MgCu 2 O 4 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 PMo 11 Cu@MgCu 2 O 4 @CS catalyst under mild reaction conditions.
