Preparation and characterization of tb, n co-doped titania nanocomposites

In this paper, Tb-N-TiO2 nanocomposites with different calcined temperature were synthesized through a facile step by sol-gel method. Besides, structural characteristics, morphology and photochemical properties of the nanocomposites were characterizedby X-ray diffraction (XRD), X-ray photo-electron spectroscopy (XPS), UV-vis diffuse reflectance spectroscopy (DRS) and Scanning electron microscope (SEM). The results showed that the Tb-N-TiO2 composites were existed in the form of anatase. The absorption of Tb-N-TiO2 in the ultraviolet and visible regions is stronger than that of TiO2 and Tb-TiO2.
