Abstract
The mixed metal oxides Bi2MoO6 and La-doped Bi2MoO6 were prepared by the sol-gel method. Then, varying quantities of the as-prepared mixed metal oxides were blended with graphene oxide (GO), employing sonication, to obtain Bi(2)MoO(6)(/)GO (BM/GO) and La-Bi(2)MoO(6)(/)GO (LBM/GO) nanocomposites. These prepared materials were characterized by different techniques such as thermal gravimetric analysis (TGA), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), and transmission electron microscopy (TEM). Dielectric properties were studied by using a precision impedance analyzer. Dielectric constant and loss tan of the synthesized composites were studied as a function of frequency by using a precision impedance analyzer. Overall, the dielectric constant (e') observed for the LBM/GO composites was higher than that of BM/GO.
