Abstract

Nanocomposites of graphene quantum dots and Au nanoparticles (GQDs/Au) are immobilized on the Fe₃O₄ nanoparticles, forming GQDs/Au/Fe₃O₄ ternary composites. The as-prepared ternary composites exhibit superparamagnetic property rendering them easy to be isolated from the reaction mixture. More importantly, they show superb catalytic activity for solvent-free oxidation of VA and other alcohols that contain an aromatic benzyl group, to the corresponding aldehydes exclusively with air as oxidant. The great stability and selectivity of the GQDs/Au/Fe₃O₄ indicate that they might be applicable catalysts for the oxidation of aromatic alcohols.
