The studies of advanced materials in environmental remediation and degradation of pollutants is rapidly advancing because of their wide varieties of applications. BiFeO 3 (BFO), a perovskite nanomaterial with a rhombohedral R3c space group, is currently receiving tremendous attention in photodegradation of dyes. The photocatalytic activity of BFO nanoparticle is a promising field of research in photocatalysis. BFO nanomaterial is a photocatalyst enhanced by doping because of its reduce bandgap energy (2.0-2.77 eV), multiferroic property, strong photoabsorption and crystal structure. The material has proven to be very useful for the degradation of dyes under visible light irradiation among other photocatalysts. Its exceptional nontoxicity, suitability, low cost and long term excellent stability makes it an efficient photocatalyst for the degradation of effluents from textile and pharmaceutical industries which ended-up in the environment and now a major concern of the modern world. This mini-review attempts to provide some detailed synthetic routes of BFO and BFO related nanomaterials and the notable achievements so far on the effect of doping the material. It also discusses the effect of crystallite size of the material and other photophysical properties and how they influence the photocatalytic process of model organic dye pollutants, to date.

“…The photogenerated e − and h + can be trapped in the MFeO 3 lattice and rapidly recombine [81,82]. However, the addition of rGO and its high electrical conductivity supplied by the π-π conjugated structure and the low amount of oxygen-containing functional groups further enhance the electrical conductivity and promote the separation of e − and h + , improving the degradation capabilities as compared to MFO or rGO alone [83,84].…”

Nanocomposite films of rGO/MFeO3 (M = Bi, La) nanofibers were grown by matrix-assisted pulsed laser evaporation of frozen target dispersions containing GO platelets and MFeO3 nanofibers. Electron microscopy investigations confirmed the successful fabrication of MFeO3 nanofibers by electrospinning Part of nanofibers were broken into shorter units, and spherical nanoparticles were formed during laser processing. Numerical simulations were performed in order to estimate the maximum temperature values reached by the nanofibers during laser irradiation. X-ray diffraction analyses revealed the formation of perovskite MFeO3 phase, whereas secondary phases of BiFeO3 could not be completely avoided, due to the high volatility of bismuth. XPS measurements disclosed the presence of metallic bismuth and Fe2+ for BiFeO3, whereas La2(CO3)3 and Fe2+ were observed in case of LaFeO3 nanofibers. High photocatalytic efficiencies for the degradation of methyl orange were achieved for nanocomposite films, both under UV and visible light irradiation conditions. Degradation values of up to 70% after 400 min irradiation were obtained for rGO/LaFeO3 nanocomposite thin layers, with weights below 10 µg, rGO platelets acting as reservoirs for photoelectrons generated at the surface of MFeO3.

“…Compared with other semiconductors, ABO 3 materials exhibit several advantages in photocatalysis due to their large scope to design, tunable band gap, and other photophysical properties attributed to the A and B cations [20]. BaTiO 3 , BiTiO 3 , and BiFeO 3 , known as a class of ferroelectric materials, were also considered in photocatalytic applications [21][22][23][24][25]. The use of BiFeO 3 /ZnFe 2 O 4 nanocomposites was reported for the photocatalytic degradation of organic dyes under visible light irradiation [26].…”

Facile synthesis of nanomaterials for advanced characterization and application is gaining interest from many researchers. In this study, Bi0.5Li0.5TiO3 nanoparticles were synthesized through the sol-gel method. The photocatalytic activity of the synthesized Bi0.5Li0.5TiO3 was investigated for degradation of methylene blue (MB) under UV irradiation. A photocatalytic efficiency of 74% was found at 150 min when the degradation was performed in the basic media, and the kinetic rate constant was calculated equal to 0.0093 min-1. The antibacterial activity of Bi0.5Li0.5TiO3 nanoparticles was evaluated against E. coli, and the results showed considerable efficiency.
