Synthesis ofFe2O3/TiO2/graphene aerogel composite as an efficient Fenton-photocatalyst for removal of methylene blue from aqueous solution

In the present study, the composites including Fe2O3/TiO2/graphene aerogel (Fe2O3/TiO2/GA) and TiO2/graphene aerogel (TiO2/GA), and graphene aerogel (GA) were synthesized by hydrothermal method. The as-prepared materials were characterized using X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray, Raman spectroscopy. The characterization results showed that the Fe(2)O(3)and TiO(2)particles were uniformly attached in GA structure, increasing number of active sites of materials and extending the light absorption range. The removal performance of Fe2O3/TiO2/GA is 97.38 % which is higher than of TiO2/GA and TiO2. The degradation data were well consisted withpseudo-first-orderkinetic model. Accordingly, Fe2O3/TiO2/GA is potential to be used as an efficient photocatalysis for treatment of MB from water.
