The newest material Fe_3O_4/TiO_2/CuO/NGP composites for removal of methylene blue dye by adsorption and photocatalysis

摘要

In this research, FCT nanocomposites were synthesized using a sol-gel method and Fe_3O_4/CuO/TiO_2 (FCT)/NGP composites were synthesized using a co-precipitation method. All prepared samples were characterized by X-ray diffraction (XRD), Fourier energy dispersive X-ray (EDX) spectroscopy, vibrating sample magnetometry (VSM), and thermogravimetric analysis (TGA). Methylene blue was used as a model for organic dyes to determine the adsorptive properties of all prepared samples. The removal of methylene blue from aqueous solution was investigated using an adsorption process. All samples followed a pseudo second order kinetic reaction. The maximum adsorption capacity was 48 mg/g.
