Synthesis of Fe3O4@GO Nanocomposites Modified with La2O3 Nanoparticles as an Efficient Catalyst for Selective Oxidation of Aromatic Alcohols to Aldehydes

Abstract

Graphene oxide (GO)-based nanocomposites decorated with metal oxide nanoparticles are promising catalysis fields owing to their multi-component interactions. In this research, a green approach for selective oxidation of benzyl alcohols to benzaldehydes was presented using novel Fe3O4@GO-La2O3 nanocomposite for the first time. The proposed nanocomposite exhibits excellent selectivity and catalytic activity for benzyl alcohol oxidation. Apart from that, this protocol can be scaled up. Absence of toxic solvent, simple product isolation, magnetic catalyst separation, and high recoverability are remarkable advantages of this approach.
