In the present study, the composites including Fe 2 O 3 /TiO 2 /graphene aerogel (Fe 2 O 3 /TiO 2 /GA) and TiO 2 /graphene aerogel (TiO 2 /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 Fe 2 O 3 /TiO 2 /GA is 97.38 % which is higher than of TiO 2 /GA and TiO 2 . The degradation data were well consisted with pseudo‐first‐order kinetic model. Accordingly, Fe 2 O 3 /TiO 2 /GA is potential to be used as an efficient photocatalysis for treatment of MB from water.
