摘要：In this work, the 3-D honeycomb-like FeCo/C nanocomposites were synthesized through the carbon thermal reduction under an inert atmosphere. The enhanced microwave absorption properties of the composites were mainly attributed to the unique three dimensional structure of the FeCo/C nanocomposites, abundant interfaces and junctions, and the appropriate impedance matching. The Cole-Cole semicircles proved the sufficient dielectric relaxation process. The sample calcinated at 600 degrees C for 4 h showed the best microwave absorption properties. A maximum reflection loss of -54.6 dB was achieved at 10.8 GHz with a thickness of 2.3 mm and the frequency bandwidth was as large as 5.3 GHz. The results showed that the as-prepared FeCo/C nanocomposite could be a potential candidate for microwave absorption. (C) 2017 Elsevier Inc. All rights reserved.
