A concentration of Sn dopant in Zn1−xSnxO nanorods(NRs)was varied from 0% to 7%. The structural and surface morphology characteristics of Zn1−xSnxO NRs/ITO composite photocatalytic films were investigated by X-Ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. In addition, photocatalytic properties of synthesized materials were evaluated by degradation rates of Rhodamine-B aqueous solutions under UV light irradiation. The SEM results indicated that, with an increasing concentration of Sn dopant in Zn1−xSnxO NRs/ITO, the effective surface areas were declined by an exponential decay function and the reduction was negligible as the Sn doping concentration was higher than 3%. With the similarity in effective surface area, the contribution of Sn in the enhancement of the photocatalytic activity of Zn0.93Sn0.07O NRs/ITO is clearly observed with 41% improvement in comparison to ZnO NRs/ITO.
