In this research, pure-phased Ni0.5Cu0.5Cr2O4 synthesis via solid-state method successfully. In the other part, the photocatalytic activity of synthesized Ni0.5Cu0.5Cr2O4 was investigated in various aspects by using Malachite green as a pollutant and compared with the number of previous photocatalysts. Photocatalysis process is a promising technique for solving many current environmental and energy issues. The environmental pollutant, especially water contaminates, can influence human health, animals and the ecosystem. Dye as one of the most important pollutant has investigated in this study. In this study, purification and crystal structure of material have been determined by X-ray powder diffraction method (XRD). The results showed that the synthesized Ni0.5Cu0.5Cr2O4 was crystallized in tetragonal structure with space group I 41/AMD. The morphology of obtained materials was modified by field emission scanning electron microscope (FESEM). Also, the material was characterized by Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA).
