The Fe3O4 nanoparticles decorated functionalized rGO sheets (FDGs) nanozymes are characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, atomic force microscopy (AFM), thermogravimetric (TGA) and vibrating sample magnetometer (VSM) analysis. FDGs nanozymes exhibits dual characteristics towards detection and degradation of harmful simazine pesticide.
