Linum usitatissimum mediated green synthesis of Cu3V2O8 nanoparticles and its photocatalytic activity studies

In the present work, Copper vanadate nanoparticles (Cu₃V₂O₈ NPs) have been Synthesised using a green solution combustion process using green fuel. The optical characteristics, structure, and morphology of the synthesized Cu₃V₂O₈ NPs have been examined using various analytical methods, including X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), UV–visible spectroscopy, photoluminescence spectroscopy (PL), and scanning electron microscopy (SEM). Based on XRD analysis, Cu₃V₂O₈ NPs have an average crystallite size of 45 nm and a triclinic phase structure. The spherical shape of nanoparticles was revealed by SEM data. The optical band gap was calculated using Tauke's theory and found to be 2.47 eV. Synthesised NPs emits red colour under UV light and it is useful in finger print detection. Cu₃V₂O₈ NPs show good action for photocatalytic degradation of Rose Bengal (RB) dye. Photocatalytic degradation (PCD) was performed by altering the dye and catalyst concentrations. The synthesized NPs have been observed as being highly effective in visible-light-driven dye degradation.
