CdS nanoparticles, Grain size, pH, Photocatalyst, Visible light.



The potential CdS nanoparticles (pH 9, 10 and 11) are synthesized by wet chemical route. The crystallographic nature and grain size of the synthesized CdS nanoparticles were analyzed using their corresponding XRD pattern. Elemental composition and purity of the CdS nanoparticles was predicted by EDX analysis. The optical band gap and characteristic absorption peak of the CdS nanoparticles is examined by UV-Visible and photoluminescence spectra analysis. The functional groups of CdS nanoparticles were founded using FTIR. Surface morphology and paticle size of CdS nanoparticles were examined using TEM and HRTEM. The photocatalytic degradation efficiency of CdS nanoparticles (pH 9, 10 and 11) on MB and RhB were analyzed using visible light irradiation.
