Catalytic Oxidation of Organic Molecules by Cold Plasma in the Presence of Magnetic Iron Compounds

Aldehydes and ketones play a crucial role as intermediates in forming C–C bonds and are present in various target molecules like pharmaceuticals and natural compounds. This study presents an effective catalytic method for producing aldehydes and ketones in the presence of cold plasma using Fe3O4@CeO2 magnetic nanoparticles as a catalyst. No need for oxidants and solvents along with a significant reduction in oxidation time are the advantages of this method compared to previous methods. Furthermore, the catalyst can be reused in up to four consecutive reactions without significant loss of activity.
