Cordyceps militaris fungus mediated Zinc Oxide nanoparticles for the photocatalytic degradation of Methylene blue dye

Zinc Oxide nanoparticles were synthesized via co precipitation methods from Cordyceps militaris fungus. In this method zinc nitrate hex- hydrate were used as a precursor. The Synthesized nanoparticles were characterized through different analytical method for identification of morphology, size, crystallinity and also purity. The nanoparticles gave highest peak at 350 in Uv–vis spectroscopy which confirmed the formation of Cordyceps zinc oxide nanoparticles. The Field emission transmission electron microscopy (FE-TEM) analyzed the morphology, purity and elemental distribution of the nanoparticles. The X-ray powder diffraction (XRD) study explored the size is about 10.15 nm. Finally, the functional group of plant and nanoparticles were identified using FT-IR analyzer. The Cordyceps militaris zinc oxide nanoparticles have ability to degrade hazardous dye Methylene blue about 97% in the presence of Uv-radiation. So this study emphasizes that the Cordyceps militaris zinc oxide nanoparticles can be the best photo catalyst for the safety of our environment from dangerous water pollution.
