Abstract
N-doped TiO2 nanomaterials were prepared with the sol-gel method. The structure and properties of the materials were characterized by using XRD, UV-Vis, SEM, EDX, and IR techniques. The optimal dose of ammonium chloride for doping is 600 mg. The optical absorption edge of N-TiO2 displays a redshift, and a long tail occurs in the presence of nitrogen in the material. Thereby, N-TiO2 may exhibit improved absorption properties under visible light and the solar irradiation. The photocatalytic activity was investigated on the degradation of rhodamine B. The optimal amount of the photocatalyst is 1.8 g/L under visible light.
