Abstract
In this work, the effect of the methods of synthesis on the phase composition and photocatalytic properties of composites formed in the section of (SrO)0.2(Bi2O3)0.8–BiFeO3 is studied on the examples of the decomposition reactions of methylene orange (MO). The studied compositions have the MO degradation degree ranging from 30 to 62% (C0 = 20 mg/L, catalyst loading of 30 mmol/L) under irradiation for 3 h with a fluorescent mercury lamp. The band gap estimated by the Kubelka–Munk function is lower than 2.6 eV for the studied compositions. This indicates the possibility of their application as photocatalysts of the visible range.
