Photocatalytic degradation of rhodamine B dye using hydrothermally synthesized NaBiTiO3 |
|
| چکیده انگلیسی مقاله |
The increasing pollution of water bodies due to the discharge of dyes from various industries has become a serious environmental concern. Rhodamine B, a commonly used dye in the textile industry, is known to be toxic and carcinogenic. In this study, we investigated the photocatalytic degradation of Rhodamine B using hydrothermally synthesized NaBiTiO3 as a catalyst. The NaBiTiO3 photocatalyst was prepared via a simple hydrothermal method and characterized using X-ray diffraction (XRD) technique. The photocatalytic activity of the NaBiTiO3 was evaluated by measuring the degradation of RhB under visible light irradiation. The results showed that the NaBiTiO3 photocatalyst exhibited excellent photocatalytic activity with a RhB degradation rate of 99% after 180 minutes of irradiation. The high photocatalytic activity of NaBiTiO3 can be attributed to its unique crystal structure, which provides a large surface area and enhances the separation and transfer of photogenerated electron-hole pairs. Furthermore, the hydrothermal synthesis method facilitated the formation of well-defined NaBiTiO3 nanoparticles with improved crystallinity and uniformity. Overall, the hydrothermally synthesized NaBiTiO3 photocatalyst showed great potential for the photocatalytic degradation of RhB and can be considered as a promising candidate for the treatment of organic pollutants in wastewater. Further studies are required to optimize the catalyst synthesis and explore its application in large-scale wastewater treatment systems. |
