The latest developments in materials based on bismuth ferrite (BFO) for piezo-photocatalytic applications are highlighted in this study. The rarely seen mix property of antiferromagnetic and ferroelectric characteristics that coexist together at room temperature makes bismuth ferrite (BFO) nanomaterial the most investigated. BFO nanostructures are a desirable option for various technological uses due to their optical, piezoelectric, and magnetoelectric coupling characteristics and their capacity to host electric and magnetic orderings concurrently. BiFeO3 is stable across a wide temperature range with a substantial residual polarization, a high Curie temperature (around 1100 K), a high Neel temperature (around 640 K), and a crystallization in a perovskite structure. Its stability has enabled its application in certain emerging fields, particularly those requiring high-performance materials in challenging conditions. Functionalities like magnetoelectric switching and piezo-photocatalysis are made possible by the tight interaction between its electric, magnetic, and structural order factors. Nonetheless, issues including phase stability, domain wall engineering, and leakage current continue to be crucial study topics. The recent developments in room-temperature BFO are examined in this chapter, along with its properties and characterization methods and possible uses in next-generation multifunctional devices.
