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

Abstract

ABO3 perovskite-type multifunctional BiFeO3 material is a commodious 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 have discussed the 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.
