Abstract

In this study, SrTi _(1-x)Fe _xO _(3-δ) (STF) powders were synthesized with a high temperature solid state reaction. The morphology, crystalline structure, particle size and size distribution of obtained samples were characterized by X-ray diffraction (XRD), electron microscopy (SEM, TEM, and SAD), and UV-vis Spectroscopy. XRD and TEM analyses indicated a structured with high crystallinity. The prepared powder was investigated by photodegradation of Methylene Blue (MB). The effect of composition (x) on degradation of Methylene Blue (MB) was studied. The obtained results showed that the SrFeO ₃ (STF ₁) sample has the best photocatalytic activity in the SrTi _(1-x)Fe _xO _(3-δ) (0≤x≤1) series and with reduced temperature of sintering the properties that improved due to smaller crystallite size and particle size.
