Preparation of Dicationic Ionic Liquid Immobilized on Fe3O4@SiO2 and Evaluation of its Catalytic Efficiency in the Oxidation of Alcohols

A novel magnetic supported dicationic ionic liquid namely Fe3O4@SiO2 center dot DIL has been prepared, and characterized by various analysis methods such as FT-IR, TEM, SEM, XRD, EDX, EDX mapping, and TGA. Afterward, catalytic activity of the Fe3O4@SiO2 center dot DIL has been examined in alcohols oxidation reaction. The resulting new nanocomposite as a heterogeneous catalyst displayed remarkable activity for the oxidation of various alcohols using H2O2 under mild reaction conditions. Eventually, the as-prepared Fe3O4@SiO2 center dot DIL catalyst was also stable and reused at least five times without losing its catalytic activity and selectivity. Magnetic recoverability of the catalyst, high yields, good compliance with green chemistry protocols and economical are some advantages of the work.
