A group 2-6 ternary semiconductor nanoparticle, CdZnS mixed with Ocimum Tenuiflorum leaf extract was prepared using chemical precipitation method at two different concentration of extract (10 ml and 20 ml). Structural, elemental, morphological, optical analyses were done. Particle size of the prepared sample was calculated using XRD pattern, also structure of the sample was confirmed. Elemental analysis was done using EDAX, confirms the elemental composition in the corresponding ratio. SEM study was employed to analyse the morphology of the sample. UV –Visible spectroscopy was done to analyse the absorption of the sample as well as Tauc plot was used to find the band gap energy. Photocatalytic activity of the sample was studied and investigated that the photocatalytic degradation was enhanced by adding the leaf extract to the CdZnS nanoparticle. The present study concentrates on the structural, morphological and optical changes occurred by adding the leaf extract. Also the effect on photocatalytic activity of CdZnS nanoparticles by adding the leaf extract.
