The present study emphasizes the fabrication of nanostructured BiFe 1− x Co O 3 ( = 0.03, 0.05) via a wet chemical route. X‐Ray diffraction confirms hexagonal crystalline structure ferrite and an increase in crystallite size from 33 to 45 nm with rise . particle size, determined using high‐resolution transmission electron microscopy, increases 30 42 higher cobalt content. direct band gap is evaluated diffuse reflectance spectroscopy, showing decrease 2.47 2.35 eV. prepared ferrites exhibit broad strong room‐temperature photoluminescence, emission wavelengths ranging 418 595 nm, indicating near‐band emissions oxygen vacancies. Physical property measurement system reveal magnetic coercivity 924 ≈759 Oe as increases. Unlike coercivity, saturation magnetization found. An ferroelectric behavior observed, where both polarization coercive field substitution. Moderate P–E loop area suggest use these materials permanent magnets charge storage. Additionally, may be employed develop hydroelectric cells due enhanced defect states, porous structures, deficiencies.

BiFeO₃ as a Next‐Generation Photocatalyst: Bridging Material Design with Environmental Remediation

ChemPhysChem, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

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