Highly Efficient Photocatalytic Degradation of Cationic Dye Over SrV6O15.85 Under Natural Light for Emerging Contaminants and Its Electrochemical Studies

A major global problem is the abundance of dangerous environmental pollutants in water bodies, both organic and inorganic. High stability and biocompatibility make the SrV6O15.85 nanorods ideal for biomedical and environmental applications like pathogen and pollutant elimination. Transmission electron microscope (TEM), energy dispersive X-ray spectroscopy (EDS), Fourier transform infrared (FTIR), X-ray diffraction (XRD), field emission scanning electron microscope (SEM), and UV–visible diffuse reflectance spectroscopy (UV–vis-DRS) were used to characterize the synthesized nanoparticles. By using UV–Vis DRS, the nanorods optical characteristics were discovered to be 3.03 eV, indicating that it may be suitable for photocatalytic devices. While the FESEM study validated the small nanorods structure for SrV6O15.85, the XRD analysis revealed that the crystallite sizes of SrV6O15.85 nanorods vary between 23 nm. The effects of initial dye concentration of crystal violet (CrV), catalyst loading, irradiation time, pH, and reusability were studied through a photocatalytic process. A glassy carbon electrode (GCE) was used to calculate the specific conductivity. The outcomes demonstrate the increased photocatalytic activity, photocatalytic stability, and increased conductivity of the SrV6O15.85 nanorods.
