Abstract Electromagnetic wave-absorbing materials play a crucial role in modern electronics, particularly stealth and communication technologies. Carbon-based demonstrate considerable potential for the development use of effective substances, attributed to their complex structure, lightweight nature, excellent corrosion resistance, affordability. Notably, nitrogen-doped carbon-based two-dimensional (2D) exhibit more pronounced depletion effect on electromagnetic waves owing increased specific surface area numerous polarization states. This article presents successful synthesis carbon (NC) 2D flakes using hydrothermal method. In addition, single Fe atoms were successfully incorporated onto surfaces, forming Fe@NC. The capabilities Fe@NC samples considerably improved, achieving minimum reflection loss (RLmin) −69.22 dB at 11.48 GHz an absorption bandwidth 5.79 GHz. enhancement wave is synergistic effects magnetic loss, relaxation processes, dipole polarization, electrical conduction loss. opens up new avenues atomically dispersed materials.
