Novel and facile reduced graphene oxide anchored Ni-Co-Zn-Nd-ferrites composites for microwave absorption

Herein, a series of novel reduced graphene oxide (rGO) anchored Ni-Co-Zn-Nd-ferrites composites have been successfully synthesized by hydrothermal process. The morphology, microstructure and electromagnetic properties were investigated by Fourier transform infrared spectrum (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectrum, scanning electron microscope (SEM), transmission electron microscope (TEM), network analyzer and vibrating sample magnetometer (VSM). The composites exhibit an excellent electromagnetic wave absorption performance, comparable or superior to that of most reported absorbers. Therefore, the rGO/Ni0.4Co0.2Zn0.4NdxFe2-xO4 (rGO/NCZNF) composites could be the potential candidates for microwave absorption applications in many fields such as energy storage and conversion.
