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 the 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 powder is used for photocatalytic degradation of typical organic
azo dye Mordant Blue 9 in concentration of 50 mg/l. Measurements were performed
for different times of irradiation and pH of the dye solution. Changes in UV-Vis
absorption spectra revealed the decolorization and decomposition of organic dye
during the photodegradation process. Photodegradation products were analyzied by
HPLC technique, and mechanism of photocatalytic degradation of organic dye was
proposed.
