Photocatalytic Activity of Heavy Metal Doped CdS Nanoparticles Synthesized by Using Ocimum sanctum Leaf Extract

Abstract

Green chemical approaches for the production of nanomaterials are currently attracted to research and industry development to minimize the use of hazardous chemicals and reduce industrial pollution. A green reagent Ocimum sanctum leaf extract was used to synthesize doped and undoped CdS nanoparticles in this work. The as-synthesized nanoparticles were characterized by using different characterization techniques such as UV-Vis spectroscopy, XRD, and TEM. The effect of doping on physicochemical properties was analyzed. Photocatalytic properties of these nanoparticles were investigated by sunlight-based photodegradation studies of methylene blue dye. The doping of these green synthesized CdS nanoparticles with heavy metals has improved photocatalytic efficiency over a given time.
