Abstract: A series of Fe2O3 and TiO2 co-doped graphene aerogel (Fe2O3–TiO2–GA) nanocomposites with a unique 3D architecture are assembled by a one-pot hydrothermal method combined with freeze-drying. The one with 30 wt% Fe2O3 exhibits the highest adsorptivity (95.0%) and the another with 25 wt% Fe2O3 displays the highest total efficiency (97.7%) including adsorption and visible light-driven photocatalytic degradation for rhodamine B dyes (20.0 mg L−1, 25 mL) within 1 h over 5.0 mg of the nanocomposites. The materials also display satisfactory cyclic stability and the removal efficiency can be 81.8% even after four runs. Additionally, a related photocatalytic mechanism is proposed.
