Fabrication of a nanocomposite catalyst via a novel and efficient
strategy remains a challenge; Fe
3O4nanoparticles anchored on graphene oxide (GO)
sheet-supported metal-organic frameworks (MOFs). In this study, the physicochemical properties of the ensuing Fe
3O4
/Cu-BDC/GO are investigated using Fourier
transform infrared spectrum, scanning electron microscopy, transmission electron
microscopy, X-ray photoelectron spectroscopy, energy-dispersive X-ray detector, and
atomic absorption spectroscopy. The salient features of the nanocomposite such as
Cu-MOF, synergistic effect with GO sheets, and magnetic separation characteristics
make it an excellent ternary heterostructure for aerobic oxidation of alcohols. The
proposed nanocatalyst and co-catalyst 2,2,6,6-tetramethylpiperidine-N-oxyl substantially enhance the catalytic performance for the aerobic oxidation under very mild and
sustainable reaction conditions. The heterogeneity of Fe
3O4/Cu-BDC/GO
composite catalyst is affirmed with the added advantage that the initial activity is
well maintained even after seven cycles.
