Improving the atom utilization of metals and clarify-ing the M-M'interaction is both greatly significant in assembling high-performance ultra-light electromagnetic wave-absorbing materials.Herein,a high-temperature explosion strategy has been successfully applied to assemble the hierarchical porous carbon sponge with Co-Fe decoration via the pyrolysis of the energetic metal organic framework.The as-constructed hybrid displays a superior reflection loss(RL)value of-57.7 dB and a specific RL value of-192 dB mg-1 mm-1 at 12.08 GHz with a layer thickness of 2.0 mm(loading of 15 wt％).The off-axis electron hologram characterizes the highly distributed numerous polarized nanodo-main variable capacitors,demonstrating the dipole and interfacial polarization along the edges of the nanopores.More importantly,the X-ray absorption spectroscopy analysis verifies the mutual interaction between the metal cluster and carbon matrix and the electronic coupling responsible for the greatly improved electromagnetic wave absorption.
