Preparation And Characterization Of Palladium Supported On Nanomagnetic Fe3o4@Hyperbranched Polyethylenimine (FE3O4@HPEI.PD) As A New Organic-Inorganic Hybrid Nanomaterial And Study Of Its Catalytic Role In The Aqueous-Phase Oxidation Of Alcohols In The Presence Of Oxone And H2o2
Paladium immobilized on magnetic nanoFe3O4@hyperbranched polyethylenimine (Fe3O4@HPEI.Pd) is an active, stable, and reusable catalyst for the selective oxidations of alcohols applying oxone (potassium hydrogen monopersulfate) and H2O2 as an oxidant in the presence of water as solvent at room temperature. Primary and secondary alcohols gave the corresponding products in good yields. In addition, the catalyst could be reused up to 13 runs without significant loss of activitie.
