Abstract
Abstract The photocatalytic degradation of textile diazo dye Naphthol Blue Black has been investigated using sunlight and Ce 1− x Mn x O 2 ( x = 0, 0.1, 0.2, 0.3 and 1.0) samples. Ce 1− x Mn x O 2 samples were synthesized by co-precipitation method and characterized by XRD, FTIR, thermal techniques and surface areas. Some solid-state studies, such as magnetic susceptibility, electrical resistivity and diffuse reflectance studies were undertaken. The extent of decolourization of the dye was determined by UV–vis spectroscopy. CeO 2 forms solid solution with Mn upto 30 mol% maintaining fluorite structure.
