Fabrication and characteristics of Zn 1–x Sn x O nanorod/ITO composite photocatalytic films
Abstract Zn 1−x Sn x O NRs/ITO composite photocatalytic films were fabricated by the hydrothermal method. A concentration of Sn dopant in Zn 1−x Sn x O nanorods (NRs) was varied from 0% to 7%. The structural and surface morphology characteristics of Zn 1−x Sn x O NRs/ITO composite photocatalytic fil...

O 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 Zn
