BiFeO3 precursor powder was synthesized by ultrasound asissted sol–
gel route at relatively low temperature, starting from Bi-nitrate, Fe-nitrate, and
ethylene glycol. Structural, optical, and photocatalytic properties of obtained
powder were investigated. X-ray diffraction analysis confirmed that thermal
treatment of precursor powder at 500 °C, led to formation of pure phase
BiFeO3. The determined band gap was 2.20 eV, indicating its potential
application as visible-light-response photocatalyst. The photocatalytic
behaviour of BiFeO3 powder was estimated by the degradation of Reactive
Orange 16 (RO16), typical azo dye. Photocatalytic activities under different pH
values were further studied. The result shows that the BiFeO3 particles exhibit
the highest photocatalytic activity in the solution with the lowest pH value.
