摘要

光催化降解对治理水污染至关重要，它利用阳光降解有机污染物。铁氧体铋（BFO）是一种多铁氧体，作为光催化剂特别有效，因为它可以通过磁力回收和重复使用。本研究采用溶胶-凝胶法合成的 BFO 纳米粒子（NPs）对有机染料的光催化降解进行了全面研究。在不同的 pH 值条件（中性、酸性或碱性）下，使用阳离子染料（亚甲基蓝和孔雀石绿）和阴离子染料（甲基橙和刚果红）在受控光催化条件下进行了降解研究。我们的研究结果表明，阳离子染料在碱性条件下降解能力更强，而阴离子染料在酸性条件下降解能力更强。从溶液中磁性回收 BFO NPs 的效率约为 98%，随后可重新用于染料降解。这项研究证明了 BFO NPs 在光催化应用中的潜力，为未来的环境清洁研究铺平了道路。

Photocatalytic Dye Degradation with Magnetically Recoverable and Reusable Bismuth Ferrite Nanoparticles

Photocatalytic degradation is vital to combat water pollution, utilizing sunlight to degrade organic contaminants. Bismuth ferrite (BFO), a multiferroic, is particularly effective as a photocatalyst as it can be magnetically recovered and reused. This study presents a comprehensive investigation into the photocatalytic degradation of organic dyes using BFO nanoparticles (NPs) synthesized through a sol–gel method. Degradation studies are conducted under different pH conditions (neutral, acidic, or basic) and using both cationic (methylene blue and malachite green) and anionic (methyl orange and Congo red) dyes under controlled photocatalytic conditions. Our findings reveal that cationic dyes show enhanced degradation in basic conditions, whereas anionic dyes are more effectively degraded in acidic conditions. The BFO NPs are magnetically recovered from the solution with approximately 98% efficiency and subsequently reused for dye degradation. This study demonstrates the potential of BFO NPs in photocatalytic applications paving the way for future research towards environmental clean-up.

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
