Spinel oxide exhibits numerous advantageous properties, leading to enhanced performance in various applications such as catalysis, sensing, batteries, dye degradation and drug storage. A significant area of current research revolves around its potential to eliminate organic pollutants from wastewater, addressing environmental concerns. In a particular study, we prepared manganese-copper oxide catalyst alone and supported by magnesium oxide by co- perception method via calcination at different temperatures of 500 and 600°C. The resulting powder of prepared precursors was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Energy dispersive x-ray technique (EDS) and scanning electron microscopy (SEM). The catalytic activity of the prepared catalyst was investigated by removing (97.3% ) of indigo carmine dye from the effluents of textile wastewater by adsorption and photocatalytic degradation; the reaction was followed by a UV/Vis spectrophotometer at λmax =610 nm. The optimum conditions of temperature and contact time and weight were studied to find out which catalysts gave the highest dye removal efficiency.
