Effect of synthesis methodologies upon the photocatalytic performance of Bi0.5Na0.5TiO3 for pollutant degradation

Abstract

In the face of mounting environmental concerns, we must seek out innovative solutions for remediation. Using nanomaterials to degrade organic pollutants in water under ambient visible light holds great promise as a safe, cost-efficient, and effective approach to addressing pollution in our water bodies. The development of novel materials capable of such pollution degradation is desired to preserve the environment. In this study, Bi0.5Na0.5TiO3 (BNT) nanoparticles are synthesized through hydrothermal and solid-state routes, and their physicochemical properties are compared to assess their photocatalytic performance. The results of the characterization studies indicate that the hydrothermally synthesized nanoparticles outperformed the solid-state synthesized counterparts in terms of photocatalytic performance. The photocatalytic degradation of Rhodamine blue dye under ambient light exposure is examined at various dye concentrations and catalyst dosages. BNT nanoparticles demonstrated excellent photocatalytic properties, stability, and recyclability, making them a promising candidate for various photocatalytic applications. The findings of this study could pave the way for the development of sustainable and environmentally friendly photocatalytic technologies for water remediation. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
