Abstract

Nanostructured SrFeO3−x was prepared by citrate under ultrasonic radiation. The photocatalytic activity was investigated with phenol as the photocatalytic degradation modal reactant under 450 W high pressure mercury lamp. The catalyst was characterized by XRD, TEM, XPS, UV–vis DRS. The results indicate that the structural and photocatalytic properties of SrFeO3−x were greatly improved by ultrasonic radiation, and its particles are well-decentralized, in smaller size, with red-shifted band edge of UV–vis adsorption spectra than that of the samples prepared by conventional method. It was supposed that the presence of different photocatalytic properties among these perovskite compounds was derived from the structural differences among them.
