摘　　要：随着社会的快速发展和电子设备的普及,电磁辐射污染问题变得尤为突出,也带来了潜在的危害。因此,开发高效的电磁波吸收材料以解决电磁辐射污染问题迫在眉睫。铁基金属有机框架(Fe-MOFs)具有高度不饱和的铁金属中心离子和多样的结构类型。通过将Fe-MOFs作为前驱体进行碳化,可以制备出铁/铁氧化物/铁碳化物均匀分布的衍生碳基化合物。这些Fe-MOFs衍生碳基化合物表现出较高的介电损耗和磁损耗能力,可有效克服当前吸波材料存在的吸收频带窄、阻抗匹配性差等问题,成为近年来备受关注的一种新型吸波材料。首先简要介绍了电磁波吸收机制,然后综述了近年来关于单金属、双金属、三金属Fe-MOFs以及由Fe-MOFs与其他材料(包括碳材料、导电聚合物、MXene和生物质)复合制备的衍生碳基吸波材料的研究进展,最后对MOFs衍生碳基吸波材料的未来发展方向进行了展望。The issue of electromagnetic radiation pollution has gained significant prominence due to the rapid development of society and the widespread use of electronic devices.Consequently,there is an imperative requirement to develop efficient materials capable of absorbing electromagnetic radiation to mitigate its detrimental effects.Fe-based metal organic frameworks(Fe-MOFs)exhibit highly unsaturated Fe metal center ions and possess diverse structural types,making them a promising avenue for addressing this issue.By employing Fe-MOFs as precursors for carbonization,one can achieve carbon-based compounds with a homogeneous dispersion of iron,iron oxides,and iron carbides.These resultant carbon-based compounds derived from Fe-MOFs demonstrate remarkable dielectric and magnetic loss properties,which can effectively address the prevalent limitations of limited absorption bandwidth and inadequate impedance matching encountered in contemporary waveabsorbing materials.Consequently,in recent years,they have garnered significant attention as promising wave-absorbing materials of a novel nature.This article presents a concise overview of the mechanism underlying electromagnetic wave absorption,and provides a comprehensive summary of recent advancements in the field of carbon-based electromagnetic wave-absorbing materials derived from mono-metallic,bimetallic,and trimetallic Fe-MOFs.Additionally,it discusses the utilization of Fe-MOF composites with other materials such as carbon materials,conductive polymers,MXene,and biomass.Lastly,this article offers a prospective analysis of the future development directions for these MOFs-derived carbon-based wave-absorbing materials.
