Abstract

Bismuth ferrite (BiFeO₃) is a multiferroic perovskite material with a narrow band gap (~2.1 eV), demonstrating significant potential as a photocatalyst for environmental remediation and sustainable energy applications. Its photocatalytic capabilities include dye degradation, air purification, wastewater treatment, and hydrogen generation, all driven by its ability to harness visible light. This review critically examines the factors influencing the photocatalytic performance of BiFeO₃ (BFO) and its doped derivatives. Advances in synthesis techniques, such as sol-gel, hydrothermal, and combustion methods, are discussed concerning particle size, crystallinity, and surface modifications. Key strategies, including rare earth element doping, heterostructure formation, and co-catalyst integration, are explored for their role in enhancing charge separation and light absorption, achieving efficiency improvements of over 90 % in some cases. The mechanistic pathways of photocatalysis, with a focus on electron-hole dynamics and radical generation, are analyzed to provide deeper insights into material performance. Despite its potential, challenges such as limited stability and rapid recombination rates persist. This review identifies critical research gaps and proposes directions for optimizing BFO's design and scalability, reinforcing its relevance as a next-generation photocatalyst for addressing global environmental and energy challenges.
