PHOTOCATALYTIC DEGRADATION ANALYSIS OF METHYLENE BLUE BY ALUMINIUM DOPED CADMIUM OXIDE NANOPARTICLES

Environmental pollution from human activities is a major challenge of civilization today. This study aimed to use Al doped CdO nanoaprticles for the purification of polluted water from dye. Al doped CdO nanoparticles have been synthesized using a simple chemical method and characterized by SEM and Raman spectra. The degradation efficiency of Al/CdO nanoparticles was studied against methylene blue by using a UV-vis spectrophotometer. The results demonstrated that the photocatalyst was efficient at 200 mg/L, the maximum amount of degradation (90.2 %) has been observed for MB after 2 hrs. The photocatalytic performance of the Al/CdO nanoparticles was stable after the nanoparticles were reused five times. The photocatalytic ability of the AldopedCdO NPs allowed the development of a low cost, high efficiency, and environmentally friendly material for water treatment applications using sunlight.
