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.
