MnCo2O4/Co3O4 Nanocomposites: Microwave-Assisted Synthesis, Characterization and Photocatalytic Performance

In this research, MnCo2 O4 /Co3 O4 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 MnCo2 O4 /Co3 O4 nanocomposites can be affected via power and time of microwave irradiation. In the next step, prepared nanocomposites were applied for photodegradation of rhodamineB and methyl violet as organic pollutants. Findings demonstrated that MnCo2 O4 /Co3 O4 nanocomposites can degrade rhodamine B and methyl violet via 58% and 61% efficiency.
