Hierarchical Porous TiO2 Fibre Synthesized by Cotton Template and Its Photocatalytic Performance

摘要：

　　Hierarchical porous TiO2 fibre was successfully synthesized using cotton as template.Microstructures of product were characterized by Field Emission Scanning Electron Microscope (FESEM),nitrogen absorption-desorption technique and transmission electron microscopy (TEM).Titanium oxide material was characterized by repetitious networks consisting of the fibres with diameter of ca.3-8 μm.The results showed that the products were composed 2-5 nm piled pores stacked by polycrystalline TiO2 nanoparticles.The small crystallite diameter (6-10 nm) and the high specific surface area (83.7 m2·g-1) of sample was believed to be resulted from wide-angle X-ray Diffraction (XRD),high resolution TEM (HRTEM) and the BET method.While the concentration of methylthionine chloride solution was 20 mg/L,catalyst amount 0.1 g/L,the reaction had a higher decoloring rate following irradiation with a UV light source,the decoloring rate can reach over 100% after 250 min.
