Degradation Of Methyl Orange

Abstract. The present work focuses on the photo-catalytic degradation of methyl orange (MO) on Erbium trioxide nanoparticles Er2O3 NPs. In this study, Er2O3 nanoparticles were synthesized and fully characterized via various techniques including; XRD diffraction, UV-Vis spectroscopy and SEM techniques. The results revealed that, the photo-catalytic activity of the prepared Er2O3 NPs towards methyl orange (MB) photo-degradation was manifested. The optimum efficiency obtained was 16 %.

In the current work, CuO nanoparticles were deposited on natural zeolite’s particles to resolve the drawbacks of zeolite catalysis. The synthesized composites were characterized by XRD, SEM, BET, and DRS analyses. The results illustrated that in the 15% CuO composite, CuO nanoparticles with a size of 21 nm are deposited on the surface of the zeolite particles. Deposition of CuO nanoparticles on zeolite’s particles decreased the specific surface area from 35 m2/g (pure zeolite) to 28 m2/g (20% CuO composite), and causes a red shift in the absorption edge of the sample to 796 nm for 20% CuO composite. In order to compare the samples’ performances in eliminating water pollutants, methyl orange dye removal was investigated. The analyses indicated that the optimum efficiency (85% in 120 min) belongs to zeolite-15% CuO composite with a band gap of 1.70 eV.

Cu-supported nano-TiO2 catalyst was prepared by forced hydrolysis method under mild condition. The morphology, composition and optical absorption properties of the samples were characterized by means of scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and UV-Vis diffuse reflectance spectroscopy (UV-VIS DRS). Visible photocatalytic activity of the samples was investigated by photocatalytic degradation experiment on methyl orange. The results indicated that nano-TiO2 was about 20nm in size with the main form of anatase, and photo response range was significantly broadened after it was loaded on the surface of Cu. The sample possessed high visible light catalytic activity, with the degradation rate of methyl orange reaching 94% under simulated natural light.
