In this research, MnCo2O4/Co3O4 nanocomposites were prepared via simple and fast microwave method. The effect of irradiation power and irradiation type (continuous and non-continuous irradiation) on crystalline structure, purity, size and morphological properties of products were investigated via X-ray diffraction (XRD) analysis, energy dispersive spectroscopy (EDS), Transmission Electron Microscopy (TEM), FT-IR and Scanning Electron Microscopy (SEM) respectively. Results revealed that shape and morphological properties of MnCo2O4/Co3O4 nanocomposites can be affected via power and time of microwave irradiation. In the next step, prepared nanocomposites were applied for photodegradation of rhodamine B and methyl violet as organic pollutants. Findings demonstrated that MnCo2O4/Co3O4 nanocomposites can degrade rhodamine B and methyl violet via 58% and 61% efficiency.Transition-metal oxides based nanocomposites exhibit novel properties that significantly have different physical and chemical properties than those matrix material and the filler resulting [1-4]. In other hand, nanocomposites have a unique and attractive properties due to small size effect [5, 6]. Magnetic nanocomposites not only have unique size-dependent properties but also get benefits from interesting magnetic properties.
