Fe(3)O(4) Nanoparticles Grown on Cellulose/GO Hydrogels as Advanced Catalytic Materials for the Heterogeneous Fenton-like Reaction

[Image: see text] Cellulose/graphene oxide (GO)/iron oxide (Fe(3)O(4)) composites were prepared by coprecipitating iron salts onto cellulose/GO hydrogels in a basic solution. X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared, and X-ray diffraction characterization showed that Fe(3)O...

description [Image: see text] Cellulose/graphene oxide (GO)/iron oxide (Fe(3)O(4)) composites were prepared by coprecipitating iron salts onto cellulose/GO hydrogels in a basic solution. X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared, and X-ray diffraction characterization showed that Fe(3)O(4) was successfully coated on GO sheets and cellulose. Cellulose/GO/Fe(3)O(4) composites showed excellent catalytic activity by maintaining almost 98% of the removal of acid orange 7 (AO7) and showed stability over 20 consecutive cycles. This performance is attributable to the synergistic effect of Fe(3)O(4) and GO during the heterogeneous Fenton-like reaction. Especially, the cellulose/GO/Fe(3)O(4) composites preserve their activity by keeping the ratio of Fe(3+)/Fe(2+) at 2 even after 20 catalysis cycles, which is supported by XPS analysis.
