“…Recently, various transition metal chalcogenides, including MoS 2 , , CuS, − CoS 2 , , Co 1–x S, , NiS/Ni 3 S 4 , CdS, , PbS, , MoSe 2 , Cu 9 S 5 , Ni x Co 3– x S 4 , , ZnS, , Co 9 S 8 , NiSe, and CoSe, have been considered as EMW absorbers. Their characteristic is like that of their metal oxides, such as the intrinsic electric conductivity, which makes them the ideal candidates as EMW absorbers.…”

Electromagnetic wave (EMW)-absorbing materials have a great impact on civil use and national defense. In this paper, a novel composite, RGO@6CoTe 2 -300 (the mass ratio of reduced graphene oxide to CoTe 2 is 1:6, annealed at 300 °C), has been obtained through a facile melt-diffusion method and solvothermal method. The as-prepared samples have shown excellent reflection losses (RL) and effective adsorption bandwidth (EAB) by controlling the loading of CoTe 2 and the annealing temperature. The sample has exhibited a RL of −62.2 dB at 13.04 GHz with the matching thickness of 3.53 mm, and the EAB reaches 8.2 GHz at 2−18 GHz. Moreover, excellent terahertz (THz) absorption property is also obtained at 0.2−2.0 THz. A RL of 54.07 dB is acquired, and the EAB covers 100% of the entire measured bandwidth. Thus, RGO@6CoTe 2 -300 can be considered as a promising EMW absorption material in both gigahertz and terahertz band ranges.
