Dielectric studies of bi2moo6/graphene oxide and la‐doped bi2moo6/graphene oxide nanocomposites

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 gra-phene oxide (GO), employing sonication, to obtain Bi2MoO6/GO (BM/GO) and La‐Bi2MoO6/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 transmis-sion 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 (ɛ’) observed for the LBM/GO composites was higher than that of BM/GO.
