Cationic and anionic dye degradation activity of Zinc oxide nanoparticles from Hippophae rhamnoides leaves as potential water treatment resource

Zinc Oxide Nanoparticles were synthesized from Hippophae rharnnoides leaves extract via co precipitation method. Synthesized nanoparticles from leaves extract having ability to generate electron hole ((e) over bar -h(+)) between the band gap of ZnO due to works as a photo catalyst in degradation of (Eosin Y, Malachite Green) textile dye. The photo catalysts were characterized with the UV-vis spectrometer, Field emission transmission electron microscopy (FE-TEM) Fourier Transform Infrared (FTIR), X-ray powder diffraction (XRD), dynamic light scattering (DLS) analysis. The UV analysis confirmed the formation of ZnO nanoparticles at 374 tim. The FE-TEM images indicates that it's having flower like shape. The XRD data confirmed the size and it is about 20.17 nm. The photocatalytic activity of the Synthesized NPs was evaluated using the Eosin Y and Malachite Green dye under Uv irradiation. Our study found that it has ability to degrade dye about 95%& 89% respectively. So Hippophae rhamnoides Leaves Zinc oxide nanoparticles (Hr-L-ZnO NPs) can be a better photo catalyst for the treatment of polluted water through textile industry.
