Abstract

Abstract: Nanostructured SrFeO₃ was prepared by citrate method under ultrasonic radiation. The photocatalytic activity was investigated with phenol as photocatalytic degradation model reactant. The catalyst was characterized by X-ray diffraction(XRD),TEM,UV-Vis Diffuse Reflectance Spec-troscopy(DRS). The results indicated that the structural and photocatalytic properties of SrFeO₃ greatly improved by ultrasonic radiation. When compared to SrFeO₃ prepared by ordinary route, the SrFeO₃ by ultrasonic radiation exhibited smaller particle size, red-shifted band edge of UV-Vis adsorption spectra.

Key words: ultrasonic radiation, photocatalytic oxides, SrFeO₃
