Characterization and photocatalytic properties of Ni-doped Sr(10)Bi(6)O(24-y).
The compound Sr(10)Bi(6)O(24-y) doped with Ni was prepared by solid-state reaction method. The obtained powders were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), UV-vis diffuse reflectance spectra and X-ray photoemission spectra (XPS). The Ni-doped Sr(10)Bi(6)O(24-y) samples assume a cubic perovskite structure with space group Fm3m (225). Bi in Sr(10)Bi(6)O(24-y) exists in the valence state of Bi(II). Photocatalytic activities of the prepared samples were evaluated using acid red G as a model organic compound. The results show that doping with 0.5 wt.% Ni can significantly improve the photoactivity of the compound Sr(10)Bi(6)O(24-y).
