The rGO/BiOBr/Bi4O5Br2 nanocomposite powders with stacked nanosheets were fabricated by one-step solvothermal method. The components, morphologies, optical properties and the separate of photo-induced carriers were explored by XRD, FT-IR, SEM, TEM, UV/Vis DRS and PL experiments. The results manifest that the reduced graphene oxide (rGO) plays a vital part in transmitting and evacuating electrons, which promotes the separate efficiency of photo-induced carriers and enhances the photodegradation efficiency of ciprofloxacin. The influences of synthesis conditions were also explored, which cover rGO content, solvent thermal reaction pH, temperature and time. In addition, a feasible photocatalytic mechanism over ciprofloxacin photodegradation under visible light irradiation was proposed.
