In recent years, the rapid development of electronic information technologies such as 5G has caused the problem of electromagnetic wave (EMWs) pollution. Two-dimensional (2D) materials have outstanding performance in anti-electromagnetic interference fields such as military, commercial and civil communications due to their nanoscale thin-layer structures and excellent properties. However, 2D materials such as MXenes and graphene have unsatisfactory impedance matching due to their high conductivity and high carrier mobility. In addition, 2D sheets are easy to agglomerate. Introducing nitrogen doping defects into two-dimensional materials has become one of the important methods to solve the above limitations.
