Microwave-Induced Deep Oxidation of Brilliant Green Using Carbon Nanotube-Supported Bismuth Ferrite

Year: 2025

Type: article

Abstract: Microwave-induced oxidation has emerged as an effective approach for water purification. In this study, bismuth ferrite-supporting carbon nanotubes with strong microwave absorption and magnetism were successfully fabricated for the degradation of brilliant green. The reactivity of bismuth ferrite in microwave fields and the role of carbon nanotubes was revealed by systematic characterization methods. Our results demonstrated that the addition of bismuth ferrite in microwave-induced system can enhance the ability of microwave-induced absorption and further induce the degradation and mineralization of brilliant green within 10 min, significantly surpassing conventional heating methods. The brilliant green decomposition by bismuth ferrite in microwave-induced process is a heterogeneous process. Its excellent performance achieved by active species-trap experiments can be attributed to microwave-induced holes. Overall, this study presented a promising material for microwave-induced elimination of brilliant green and other dyes in aqueous media, which can provide the basis for the environmental application of microwave radiation to water purification and wastewater treatment.
