Review—State of the Art of the Multifunctional Bismuth Ferrite: Synthesis Method and Applications

Abstract

ABO3 perovskite-type multifunctional BiFeO3 material is a good candidate for a variety of device applications such as photocatalyst, gas sensor, biosensor, thermoelectric material, and so on due to its remarkable magnetoelectric coupling property. The future scope of this perovskite material can be broadened by its cost-effective, highly efficient, and easily available nature. Herein, we discuss recent developments in multifunctional BiFeO3 based on two crucial applications such as sensors and photocatalyst from the recent research literature. We have also addressed the effects of doping which includes the bandgap reduction, finer pore size, and crystallite size leading to higher efficiency. Additionally, the BiFeO3 composites due to their larger surface area involve more active molecules on the surface thereby increasing the efficiency even more. Finally, some of the future scopes of the research are also addressed in this article.

Impact of Crystallite Size and Phase Boundaries on Magnetic and Thermoelectric Properties of Cu-Added BiFeO3

“…10 Based on the above reasons, as mentioned in multiple reports, BiFeO 3 was synthesized via the coprecipitation method. 11 This work aims to synthesize Cu-doped BiFeO 3 via a coprecipitation method. Cu presence was identified in the secondary phase in addition to the bismuth ferrite (BFO) phase.…”

Influence of using different types of microreactors on the formation of nanocrystalline BiFeO3

“…The morphology, size and structure of nanoparticles, the presence and amount of impurity phases in a nanopowder can significantly affect the mechanical and functional properties of the materials obtained from them [1][2][3], including the magnetic, electrical, photocatalytic properties of bismuth orthoferrite [4][5][6][7][8][9][10][11]. These reasons stimulate the development of methods for synthesis of bismuth orthoferrite nanopowders, which would provide their morphological characteristics, dispersed and phase composition, necessary to obtain materials with needed properties.…”

Spray pyrolysis-derived robust ferroelectric BiFeO3 thin films

“…Bismuth ferrite is one of the very few examples of functional ferroic materials which display a coupling between the ferroelectric and magnetic properties at room temperature, and thus has been actively explored for low-energy spintronics devices. [1][2][3] Additionally, due to its high polarization value (B100 mC cm À2 ), superior electromechanical coupling, relatively low electronic bandgap, and easily tuneable crystal structure, for instance by doping or strain, BiFeO 3 (BFO) has found applications [4][5][6][7][8][9][10][11][12] in charge-based or resistance switching random access memories, sensors, strain-engineered morphotropic phase boundaries, photovoltaics, and domain wall electronics and devices among others. A significant research emphasis has been on the fabrication of high-quality BFO thin films.…”
