The Pt/Bi2WO6 composite photocatalyst has been successfully synthesised via a photodeposition method. The morphology and the structure of the Pt/Bi2WO6 composite samples are characterised by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and UV-vis diffused reflectance spectra. Also discussed are the photocatalytic activities of the obtained samples with different amounts of Pt by investigating the degradation of ciprofloxacin under a Xenon lamp irradiation and it is found that the Pt/Bi2WO6 sample with a 1.0 wt% Pt has the highest photocatalytic activity, which is two times of that compared with the pure Bi2WO6. Furthermore, the photocatalytic mechanism of the above degradation has been studied.
