Research progress of carbon-based wave-absorbing materials derived from Fe-MOFs
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 wave-absorbing 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.
