Optical and Photocatalytic Activity Of Cmc Capped Zinc Selenide Nanoparticles Under UV Light Irradiation Using Congo Red Dye

T. Anantha Kumar, P. Mariselvi, G. Alagumuthu


In this work, we report the, optical, structural morphology and photocatalytic activity of CMC capped zinc selenide nanoparticles, which have been synthesized by hydrothermal method. CMC is acted as capping agent. The nanoparticles were characterized using XRD, SEM with EDAX, AFM, TEM and UV-Vis absorption spectroscopy. The structural properties of nanoparticles have been characterized by X-ray diffraction (XRD) analysis. The XRD patterns show a hexagonal Wurtzite crystal structure. The surface morphology of the nanoparticles was analyzed by SEM and AFM analysis. Absorption spectra have been obtained using UV-Vis spectroscopy to find the optical band gap. In addition, photocatalytic degradation of congo red in aqueous solution was performed using CMC capped zinc selenide nanoparticles under the illumination of UV light.
