Abstract

The LaFeO3/ZnO/NGP composites with different amounts of NGP loading were synthesized using the co-precipitation method. The samples were characterized by X-ray diffraction (XRD) and thermogravimetric analysis (TGA) spectroscopy. The diffraction pattern of the samples exhibited orthorhombic, hexagonal wurtzite and graphite-like structure of LaFeO3/ZnO/NGP composites. The thermal stability of the samples decreased with the increasing amount of NGP loading. The adsorption capability of the samples was tested for removing methylene blue (MB) dye organic pollutant. Compared to LaFeO3 nanoparticles and LaFeO3/ZnO nanocomposites alone, the incorporation of NGP increased the absorption capability of the prepared samples. The absorption capability of the samples increased with the increase of NGP content. The adsorption kinetic model of the prepared composites followed the pseudo-second-order kinetic reaction, while the adsorption mechanism of the samples followed the Langmuir adsorption-isotherm model.
