Abstract Herein, a series of CoCr 2 O 4 /wt%NiFe (CCO/wt%NFO) composites are successfully synthesized by simple solution combustion method combined with mechanical grinding techniques. The preparation CCO/wt%NFO result in an estimation its photocatalysis performance removing tetracycline hydrochloride (TC) as model antibiotic pollutants. results show that the percentage NFO mass have great influence on morphology and composites. Superior is observed CCO/25%NFO prepared at 25%. photocatalyst used removal ratio 81% for TC. generation hydroxyl radical (•OH), superoxide anion (•O − ) holes (h + largely responsible degrading TC through presence optimal operating conditions involve initial concentration pH being 50 mg L −1 = 13, respectively. Furthermore, highly reusable stable during photocatalytic process. degradation pathway, toxicity, mechanism extensively examined spectrometry, toxicity analysis, energy band theory.

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

ChemPhysChem, Год журнала: 2025, Номер unknown

Опубликована: Март 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.
