The NiO/NiCo2O4 mixtures with distinctive yolk-shell construction have been synthesized by a easy hydrothermal route and subsequent thermal remedy. The fundamental distribution, composition, and microstructure of the samples have been characterised by transmission electron microscopy (TEM), X-ray diffraction (XRD), and scanning electron microscope (SEM), respectively. The microwave absorption property was investigated through the use of vector community evaluation (VNA). The …
