Abstract: A series of Ni-doped TiO2 materials with rich pore structure are synthesized by using nickel nitrate solution treated tobacco stalks as templates.The samples are characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM),transmission electron microscopy (TEM),nitrogen adsorption-desorption analysis,X-ray photoelectron spectroscopy (XPS) and UV-visible diffuse reflectance spectroscopy (UV-Vis DRS).The results show that Ni doping has great influence on the specific surface area and band gap width of the material.The performance of the materials in photocatalytic degradation of Rhodamine B (Rh B) is investigated under visible light irradiation.It is found that the sample prepared at a molar ratio of Ni to Ti being 0.5% (0.5 Ni-STiO2) has the best photocatalytic degradation effect on Rh B,over which the degradation rate constant is 2.4 times that over the undoped sample (STiO2).
