Degradation of Congo Red (CR) Catayzed by Nanostructured ceria

Nanostructured CeO2 is a promising catalyst in many applications because it is one of the most reactive rare earth metal oxides. It plays a vital role in technologies for environmental and energy related applications, such as heterogeneous catalysis. Nanostructured ceria with various morphologies exhibits excellent physicochemical properties. In this thesis, nanostructured CeO2 has been synthesized by previously published surfactant-assisted green chemical precipitation method. As a cationic surfactant CTAB (cetyltrimethylammonium bromide) was used and as a cerium precursor cerium chloride hexahydrate. Synthesized compounds were characterized by powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR). The catalytic activity of the nanostructured CeO2 was tested towards the degradation of Congo Red (CR) synthetic dye in different shapes (spherical, nanorods and mixture of both). The results show excellent removal capacity of this organic pollutant and therefore it can be a promising candidate for wastewater treatment.
