Mesoporous graphene and tourmaline co-doped titania composite was prepared using a direct sol–gel co-condensation combined with solvothermal treatment technique. The composite exhibited a three-dimensional (3D) interconnected mesostructure and anatase phase-structure with a large surface area (218m2g−1) and uniform pore size. Compared with pure titania, the photocatalytic activity of the composite was enhanced significantly towards aqueous organic pollutant rhodamine B and norfloxacin degradation under simulated sunlight irradiation. Subsequently, this composite was successfully applied to the actual eutrophic water treatment.
