A novel Fe/nanoporous carbon (Fe/NPC) composite was synthesized via Fe 3 O 4 nanoparticles coating in metal–organic framework. The pyrolysis conditions are carefully optimized, and the effects of pyrolysis temperature on electromagnetic parameters have been systematically analyzed. Among these candidates, the Fe/NPC composite pyrolyzed at 800 °C (Fe/NPC‐800) shows the eminent microwave absorption due to interface polarization and well matched characteristic impedance. The results indicate that the effective reflection loss absorption bandwidth of Fe/NPC‐800 reaches 5.6 GHz (12.4–18 GHz) with a thickness of 1.8 mm. It provides an exciting clue for the fabrication of lightweight and highly effective microwave absorbers in the future.
