%X The [email protected]2/holey reduced graphene oxide composite was successfully prepared by combining liquid-phase reduction reaction in argon atmosphere with high-temperature calcination. The [email protected]2/holey reduced graphene oxide composite was characterized by X-ray diffraction, X-ray photoelectron spectroscopy, vibrating sample magnetometer, Fourier transform infrared spectroscopy, Raman spectroscopy, transmission electron microscopy and scanning electron microscopy analysis and exhibit excellent electromagnetic wave absorption properties. The maximum reflection loss of [email protected]2/holey reduced graphene oxide composite reaches ¨C46.28 dB at 16.16 GHz with the thickness of 1.5£¿mm and the absorption bandwidth with the reflection loss below ¨C10 dB was up to 3.92 GHz (from 14.08 GHz to 18 GHz) with the thickness of 1.5£¿mm. The absorption bandwidth with RL below ¨C10 dB is up to 12.64 GHz. It is believed that the [email protected]2/holey reduced graphene oxide composite can serve as an excellent microwave absorber
