BiFeO 3
BiFeO 3 compound shows simultaneous multiferroic and magnetoelectric behaviors
at ambient conditions that led to widely employing of BiFeO 3 in the arena of
nonvolatile memory, spintronic, sensors, and piezoelectric apparatus (Lam et al.
2017; Ponraj et al. 2017). BiFeO 3 photocatalyst having rhombohedral disordered
perovskite is a new kind of reliable solar light-activated photocatalyst within the
organic polluter remediation because of its small band gap and great chemical
stability. Last year, BiFeO 3 attracted considerable attention in photocatalytic environmental applications (particular degradation dye pollutants such as methylene blue
and rhodamine B due to its weak ferromagnetic feature led to recycling from treated
solution (Ponraj et al. 2017). Optical band gap of BiFeO 3 reported between 2.2 and
2.8 eV in literatures. Mesoporous BiFeO 3 hollow sphere was synthesized and used
for degradation of rhodamine B and 4Àchlorophenol under 500 W Xe-lamp irradiation (Gao et al. 2015). Soltani et al. (Soltani and Entezari 2013a) demonstrated that
reactive black 5 bears three main UV/visible peaks at wavelengths of 620, 312, and
254 nm. The generation of some new intermediates such as sulfone, sulfonate, and
amine groups prepared in the UV/visible regions is the reason for observation of
