A novel Bi2WO6 micro/nano-structures with pH-controlled shapes were synthesized by Novel template-free solvothermal synthesis method. Multiple technologies were applied to characterize the as-synthesized samples including X-ray powder diffraction(XRD), field emission scanning electron microscopy(FE-SEM), UV-vis diffuse reflectance spectrum(UV-vis), nitrogen absorption/desorption isotherm. The photocatalytic activity of the samples was evaluated by degrading ciprofloxacin simultaneously.It is demonstrated that the morphologies of composites were controllable with pH of reactant solution .The result showed that nearly 90% of all the target antibiotics were degraded within 180min utilizing the Bi2WO6 synthesized under pH of 7
