In this work, we have demonstrated the enhancement of the microwave absorbing capability of Ni-modified MXene within a frequency range of 2-18 GHz. The Ni-modification makes MXene able to attenuate microwave energy through magnetic loss as well as a strong dielectric loss. The effective absorbing bandwidth is greatly broadened, especially at the lower frequency of 2-8 GHz. The synergistic effect of dielectric loss and magnetic loss and the structure effect are believed to be the main reasons behind the broadening of the effective microwave absorbing bandwidth.
