摘要/Abstract

摘要： 金属有机框架(MOF)衍生的多孔金属/碳复合材料由于具有大的表面积和孔体积,引起了电磁波吸收领域研究者的广泛关注。本文采用溶剂热法合成双金属NiCo-MOF,再通过煅烧制备了具有Yolk-shell结构的NiCo/C复合材料,采用SEM、XRD、拉曼光谱以及磁强计(VSM)等分析方法对比研究了不同Ni、Co质量比对NiCo/C复合材料吸波性能的影响。结果表明,随着Ni、Co质量比的变化,吸波性能发生了显著的改变。在9.4 GHz的频率下,Ni₁Co₁/C复合材料的性能达到最佳,最小反射损耗为-56.8 dB,有效吸收带宽为5.5 GHz。分析该复合材料的吸波机理发现,电磁波的多重反射、界面极化损耗、自然共振和交换共振是导致其吸波性能提高的重要原因。本文的研究结果为纳米多孔双金属MOF复合材料的制备与性能研究提供了研究思路。

Abstract: Due to having large surface area and pore volume, the porous metal/carbon composites derived from the metal organic framework (MOF) have attracted widespread attention in the field of electromagnetic wave absorption. In this paper, bimetal NiCo-MOF was synthesized by the solvothermal method, and NiCo/C composite with Yolk-shell structure was prepared by calcination. The effects of different mass ratios of Ni and Co on the absorption performance of NiCo/C composites were investigated by SEM, XRD, Raman spectroscopy and VSM analysis.The results show that with the change of mass ratio of Ni and Co, the absorption performance is changed significantly. The performance of Ni₁Co₁/C composite is the best state, which has a minimum reflection loss of -56.8 dB and an effectively absorbing bandwidth of 5.5 GHz under the frequency of 9.4 GHz. By analyzing the absorption mechanism, it is found that multiple reflection, interfacial polarization loss, natural resonance and exchange resonance are the important reasons for improving the absorption performance of the composite. It provides an inspiring method for the preparation and properties of nano-porous bimetal MOF composites.
