? 2022 Elsevier B.V.The application of microwave absorbing materials is one of the important means to reduce electromagnetic pollution. Transition metal phosphides as absorbers with high conductivity attract researchers' interest. Therefore, in this paper, the novel cobalt phosphide wrapped by reduced graphene oxide (CoP/RGO) were prepared by simple hydrothermal and phosphating reaction. Meanwhile, the introduction of RGO is beneficial to enhance the conductive loss and polarization loss of materials. Compared with most of the reported transition metal phosphate-based absorbents, CoP/RGO has a better microwave absorption (MA) performance. The minimum reflect loss (RLmin) value can reach ? 52.60 dB with 2.05 mm, and the maximum effective absorption bandwidth (EAB, RL<?10 dB) can reach 5.04 GHz at 2.25 mm. The superior MA performance of CoP/RGO composites makes it possible to be a candidate as an absorber.
