“…In contrast, the presence of bismuth iron oxide phases such as Bi 46 Fe 2 O 72 (PDF #20‐0170) and Bi 2 Fe 4 O 9 (PDF #25‐0090) may be attributed on the kinetics of formation, due to which, some impurity phases are always obtained along with the stoichiometric BiFeO 3 phase (PDF #71‐2494), as the major phase during the synthesis of BFO MNPs. Such impurity phases exist in multiple relevant reports …”

The explosive expansion of multiferroics literature in recent years demonstrates the fast‐growing interest in this field. Although bismuth ferrite is one of the most extensively investigated multiferroic compounds combining magnetoelectric, i.e., antiferromagnetic and ferroelectric features at room temperature, the challenge of producing single‐phase particles remains because the role of multiple synthetic parameters must be unraveled. Herein, the facile synthetic route of aqueous coprecipitation is selected as the first synthetic step, followed by a 700 °C annealing stage to synthesize bismuth ferrite nanoparticles (NPs). This article aims to clarify the influence of ingredients such as precursors: base solution, acid and the Bi/Fe molar ratio, and the role of synthetic parameters such as pH level and reaction temperature toward higher yields of purer crystalline phases. Both structural and magnetic features' performance outline the significance of both stages on forming BiFeO3 single‐phase NPs with the absence of any secondary bismuth oxide phases, a crucial issue for multiferroic features at room temperature.

“…Bi(NO 3 ) 3 · 5H 2 O and Fe(NO 3 ) 3 · 9H 2 O were dissolved in 200 mL of distilled water and stirred for 20 min to form a clear solution. The precursor solutions were precipitated using ammonia (2.5 M) at various pH levels, and it was found that the pure phase was observed at approximately pH 10 [16]. We have used the co-precipitation method extensively for the synthesis of several perovskite compositions, such as BaRuO 3 , La 3.5 Ru 4.0 O 13 , LaMnO 3 , La 0.8 Ba 0.2 MnO 3 , PrMnO 3 , Pr 0.8 Ba 0.2 MnO 3 , SrCoO 3 , and Sr 0.8 Ce 0.2 CoO 3 .…”

Perovskites are mixed-metal oxides that are attracting much scientific and application interest owing to their low price, adaptability, and thermal stability, which often depend on bulk and surface characteristics. These materials have been extensively explored for their catalytic, electrical, magnetic, and optical properties. They are promising candidates for the photocatalytic splitting of water and have also been extensively studied for environmental catalysis applications. Oxygen and cation non-stoichiometry can be tailored in a large number of perovskite compositions to achieve the desired catalytic activity, including multifunctional catalytic properties. Despite the extensive uses, the commercial success for this class of perovskite-based catalytic materials has not been achieved for vehicle exhaust emission control or for many other environmental applications. With recent advances in synthesis techniques, including the preparation of supported perovskites, and increasing understanding of promoted substitute perovskite-type materials, there is a growing interest in applied studies of perovskite-type catalytic materials. We have studied a number of perovskites based on Co, Mn, Ru, and Fe and their substituted compositions for their catalytic activity in terms of diesel soot oxidation, three-way catalysis, N2O decomposition, low-temperature CO oxidation, oxidation of volatile organic compounds, etc. The enhanced catalytic activity of these materials is attributed mainly to their altered redox properties, the promotional effect of co-ions, and the increased exposure of catalytically active transition metals in certain preparations. The recent lowering of sulfur content in fuel and concerns over the cost and availability of precious metals are responsible for renewed interest in perovskite-type catalysts for environmental applications.

“…Due to the wide range of applications, bismuth ferrite has been synthesized using different methods such as hydrothermal synthesis [5], polymer-assisted hydrothermal synthesis [6], microwavehydrothermal synthesis [7], microwave induced solid-state decomposition [8], sol-gel process [9], sonochemical [10], co-precipitation [11] and etc. Solid state synthesis is one of the most useful routes for preparation of bismuth ferrite.…”

Magnetic bismuth ferrite nanoparticles were prepared by microwave method. We used Iron (III) nitrate nonahydrate, bismuth nitrate as initial reagents, glycine as an organic template and ammonium nitrate as co-oxidizer. This solid phase reaction was done under microwave radiation with the power of 900 W for 20 minutes. After the treatment, the result compound washed with distilled water and ethanol and dried at 70°C. This method has advantages such as simple, fast, reduces energy and environmental friendly. The product was characterized by Powder X-ray diffraction (PXRD), Scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) and vibrating sample magnetometer (VSM). Also, the adsorption behavior of congo red as an organic pollutant was evaluated.
