| Abstract | Metal-organic framework (MOF) derived composite is one of the most promising lightweight electro-magnetic wave (EMW) absorbers. However, it is still a significant challenge to raise its effective absorbing bandwidth (EAB) for enhancing the EMW absorbing performance. Herein, a novel Co/C composite derived from Co-MOF with a large saturation magnetization was fabricated via a solvothermal reaction and a subsequent annealing process. The resultant Co/C composite shows prominent EMW absorbing perfor-mance. The EAB of the Co/C composite obtained at 700 degrees C reaches an ultra-wide bandwidth of 6.9 GHz at 2.5 mm which is much higher than that of most other MOF-derived composites. The excellent EMW ab-sorbing performance is mainly attributed to the perfect impedance matching, caused by the synergetic effect of dielectric loss and magnetic loss. Hence, this work provides a simple method for the synthesis of MOF-derived Co/C composites with prominent EMW absorbing ability.(c) 2022 Elsevier B.V. All rights reserved. |
