Three-dimensional flower-like α-Fe2O3 structures were grown on the surface of ordered mesoporous carbon nanorods through a facile hydrothermal method, and their electromagnetic (EM) parameters were measured at 2–18 GHz. The special geometric morphology and proper magnetic loss of α-Fe2O3 nanoparticles and the strong dielectric polarisations and relaxations in the composites contribute to its excellent EM wave absorption. A reflection loss exceeding −10 dB was obtained at 9·9–16·1 GHz for an absorber of 50 wt-% loading with 2·50 mm thickness layer. The result provides a novel EM wave absorbing material to meet the practical applications.
