摘要

Abstract FeNi3@SiO2-decorated reduced graphene oxide (FeNi3@SiO2@rGO) nanocomposites were prepared by combining liquid-phase reduction reaction with hydrothermal reaction. TEM results illustrate that the FeNi3@SiO2 nanoparticles (NPs) are of core-shell structure with an average diameter of about 50 nm. XPS analysis shows the reduction of GO happens in the hydrothermal process. The maximum reflection loss (RL) is -49.4 dB at 8.64 GHz with an optimal thickness of 3.8 mm and the bandwidth (RL<-10 dB) is 3.38 GHz ranges from 6.72 to 10.1 GHz. The microwave absorption mechanism is mainly attributed to the dielectric loss. It is believed that the FeNi3@SiO2@rGO nanocomposites can serve as an excellent microwave absorbent and can be widely used in practice.
