Abstract
MFe2O4 (M = Mn, Mg)/reduced graphene oxide (MFe2O4/RGO) nanocomposites were synthesized through a simple and novel pressure cooker assisted solvothermal method. The nanocomposites were characterized using x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), UV-Vis absorption and photoluminescence spectroscopy, transmission electron microscopy (TEM) and x-ray photoelectron spectroscopy (XPS). The optical analyses showed that, the MFe2O4/RGO materials have good photoluminescence (PL) with excitation dependent PL properties while magnetic characterization indicated that, the as-synthesized MFe2O4/RGO nanocomposites exhibits superparamagnetic behavior. Dielectric spectroscopy analysis showed enhanced dielectric constant, dielectric loss and AC conductivity for MFe2O4/RGO, compared to graphite oxide (GO). The study on methyl blue (MB) dye adsorption revealed that, the as-prepared nanocomposites have strong and recyclable adsorption for MB.
