Abstract
The compound Sr10Bi6O24ây 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 Sr10Bi6O24ây samples assume a cubic perovskite structure with space group Fm3m (2Â 2Â 5). Bi in Sr10Bi6O24ây 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 0.5Â wt.% Ni can significantly improve the photoactivity of the compound Sr10Bi6O24ây.
