Heterostructure design of MOFs derived Co9S8/FeCoS2/C composite with efficient microwave absorption and waterproof functions
文献摘要：
At present,the problem of electromagnetic wave(EMW)pollution is critical,and the design of high-performance absorbers is of great significance.Based on the synergy between dielectric and magnetic losses,and between multicomponents in heterostructures,the development of light-weight absorbers with a strong absorption capability and multiple scattering is a promising strategy to achieve high-performance absorbers.In this work,CoFe-MOF precursors with a bouquet-like structure were prepared via the hydrothermal method,and Co7Fe3/C and Co9S8/Fe/CoS2/C composites were obtained through a carbonization and sulfuration treatment during the high-temperature pyrolysis process,respectively.The experimental and theoretical results show that the Co9S8/FeCoS2/C composite has a better EMW absorp-tion performance,and its optimal reflection loss(RL)value is-53.9 dB at a low filler loading of 20 wt.％,which is due to the S doping that enhances the interface polarization relaxation process and improves the impedance matching characteristics.Moreover,the Co9S8/FeCoS2/C composite can be as candidates of high-efficiency absorbers in extreme application environments.
