AB  - The preparation of pure BiFeO3 (BFO) powders and ceramics is still a challenging issue
because of a narrow temperature range of phase stabilization. The mechanism of BFO
synthesis reaction usually includes formation of secondary phases. In this work, BFO
precursor powders were synthesized by hydro-evaporation (HE) and ultrasound (US) assisted
sol–gel method. BFO precursor powder obtained by HE method was calcined at various
temperatures ranging from 620°C to 770°C for 6 h; while powder obtained by US route was
thermally treated at 500°C for 30 min, to form resulting BFO powders. Structural, optical,
and photocatalytic properties of the obtained powders were investigated. The X-ray
diffraction analysis of BFO powders prepared by HE method, confirmed the presence of
secondary phases, Bi25FeO39 and Bi2Fe4O9. On the other hand, X-ray diffraction analysis
confirmed the formation of pure phase nanosized BFO obtained by US route. Therefore, BFO
powder obtained by US method was selected for photocatalytic degradation of typical
organic azo dye Mordant Blue 9 in concentration of 50 mg/l. The determined band gap of US
obtained BFO powder was 2.20 eV, indicating its potential application as visible-lightresponse photocatalyst. Measurements were performed for different times of irradiation
and pH of the dye solution. Photodegradation products were analysed by HPLC technique,
and mechanism of photocatalytic degradation of organic dye was proposed.
