Simple Preparation and Characterization of CdS Nanoparticles as a Highly Efficient Photocatalyst under Visible LED Light Irradiation

The nanosized cadmium sulphides (CdS) were synthesized via a simple chemical precipitation method by using Mercaptoethylamine hydrochloride (MEA) as a capping agent. By using different concentration of capping agent we could get different sizes of CdS. The synthesized CdS nanoparticles were characterized by XRD, SEM, DRS, FTIR and UV-Vis spectrum. Photocatalytic activities of nanoparticles were investigated for degradation of methylene blue (MB) under blue high power LED (3W) irradiation as a visible light source.
