摘要：
To enhance the photo degradation efficiency for oxytetracycline (OTC), Fe-TiNTs were prepared via a simple and fast hydrothermal process using TiO2 powder as precursors. A wide range of techniques, such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), Brunauer-Emmett-Teller (BET) and Ultraviolet-visible spectroscopy (UV-vis) were applied to characterize as-obtained Fe-TiNTs. Moreover, we have studied the photocatalytic properties of the Fe-TiNTs in the degradation of OTC. The results of our investigation and analysis have shown that regularly uniform nanotubes were fabricated by the hydrothermal treatment, and they had homogeneous tubular structures and open ends. UV-vis spectra of Fe-TiNTs demonstrated its absorption edge had remarkable red shift to the visible light region. Fe-TiNTs exhibited higher photocatalytic activities than that of TiNTs and TiO2 powder when they were evaluated to degrade OTC under visible light irradiation.
