The rGO/BiOBr/Bi 4 O 5 Br 2 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.
