The objective of present studies demonstrates a simple soft chemical method to prepare Selenium nanoparticles. Various characterization techniques such as XRD, SEM, and UV-visible spectroscopy has been used to characterize synthesized nanoparticles. The X-ray diffraction studies synthesized indicated the formation zinc selenide (ZnSe) along with Se nanoparticles. The Scanning electron microscopy (SEM) showed spherical shape Se nanoparticles of average size about 525 nm. The synthesized nanoparticles were also studied for their photocatalytic activity for degradation of methylene blue under ultraviolet light irradiation. The study showed 99 % degradation efficiency in 90 min. It has been observed that the presence of Selenium in ZnSe reduce the photo-corrosion under light irradiation and improved photocatalytic stability.
