Present work focus onsynthesis of ZnO and MgO nanoparticles (NPs) by curry leaves through Green approach. This method is non-toxic and eco-friendly. The curry leaves extract acting as a reducing agent in thereaction. The biosynthesized NPs were characterized by different analytical techniques. X-Ray Diffractometer (XRD) for to calculate the average crystalline size, Particle Size Analyser for average particle size, Scanning Electron Microscope (SEM) for morphological studies, UV-Visible spectroscopy (UV-Vis)for to analyze the absorption patterns.The NPs exhibit potential photocatalytic activity towards the degradation of methylene blue (MB) and Methyl red(MR)dye upon exposure to UV light. The study successfully shows a simple and eco-friendly method forthe synthesis of efficient multifunctional ZnO/MgONPs using green synthetic approach. Photocatalytic property of the ZnO/MgO NPs wereexamined by photo degradation of MB and MR under UV illumination. The biosynthesized nanoparticles showed photocatalytic activity under the UV light enhancing the degradation rate of methylene blue (MB) and Methyl red(MR), which is one of the main water-pollutant released by textile industries. The study successfully demonstrates synthesis of ZnO/MgO NPs by simple ecofriendly route usingCurry leaves as fuel that exhibit superior photo catalytic activity.
