Visible light induced Rhodamine B Degradation using NaBiO₃ nanophotocatalysis

Abstract

investigations by Kou et al. delved into the photocatalytic oxidation of polycyclic aromatic hydrocarbons using NaBiO3 under visible light irradiation. Their findings underscored the efficiency of NaBiO3 in degrading organic compounds [1]. Chang et al. extended this research by reporting on the photocatalytic degradation of sodium pentachlorophenate (PCP-Na) and 4-t-octylphenol (4-t-OP) over NaBiO3 under visible light irradiation, demonstrating that NaBiO3 could effectively decompose these compounds [2]. The degradation of Rhodamine-B (RhB), a common triphenylmethane dye used in textile, printing, food, and cosmetic industries, was a central focus of Yu et al.'s investigation. Notably, triphenylmethane dyes like RhB pose a significant environmental concern due to their persistence in aquatic environments. These dyes can lead to aesthetic pollution and have long-term adverse effects on aquatic ecosystems [3]. In the context of visible light-induced photocatalytic degradation of N-ethyl-containing dyes, the study highlights the versatility of NaBiO3 in tackling different mechanisms of pollutant degradation, further emphasizing its potential as a promising photocatalyst in environmental remediation. In summary, NaBiO3 has emerged as a powerful photocatalyst with diverse applications in pollutant degradation, offering solutions for the removal of various organic compounds from aquatic environments. Its efficiency in harnessing visible light for catalytic processes makes it a compelling candidate for addressing environmental pollution challenge.
