For adapting to the complex electromagnetic environment, developing materials with tunable morphology enabling broadband wave (EMW) absorption is undoubtedly a challenging task. In this work, Y2O3/Ni@ N-doped carbon (YNC) composites were prepared by solvothermal method and high-temperature carbonization using metal-organic frameworks (MOFs) as raw materials. By adjusting molar ratio of Y3+/Ni2+, changed from microsphere spiky microspheres, then dumbbell-shape, different morphologies achieved tune impedance matching. Especially, microspheres exhibited stronger EMW performance than other morphologies. When Y3+/Ni2+ was 3:7, minimum reflection loss YNC reached −64.74 dB at 25 wt% filling ratio. At thickness 2.02 mm, effective bandwidth value 6.56 GHz (11.44−18.00 GHz), covering entire Ku band. Notably, controllable matching porous structure in multiple bands (C, X, Ku). The superior attributed composites, achieving balance attenuation capacity. Furthermore, presence magnetic Ni nanoparticles provided capability for composites. Density functional theory indicated that formation heterostructures boosted carrier mobility, facilitating electron transfer across interfaces, thus increasing interfacial polarization. Therefore, study offered novel approach designing rare-earth based MOFs derived absorbers capability.

Abstract Molybdenum disulfide (MoS 2 ) with tunable phase transformation, especially high 1T‐phase content, has been a promising electromagnetic wave (EMW) absorber. However, precise regulation of MoS transformation still remain challenges. Herein, facile Anderson‐type polyoxometalate (XMo 6 ,X = Cr, Mn, Fe, Co, Ni) precursor strategy is reported to construct ‐based bimetallic sulfide hybridsfor regulating permittivity and EMW absorption. The well‐defined structures tailorable compositions XMo offer the opportunity conduct controllable on engineering . disparity transition metal sulfides (TMSs) in chemical reactivity leads sulfur vacancy (V s ), which induces from 2H 1T. tuning electronic structure enables permittivity, further verified by density‐functional theory (DFT) calculations. optimized FeS/MoS /carbon fiber powder richer 1T‐phase, V , heterointerfaces multi‐component, exhibit minimum reflection loss −51.82 dB (1.72 mm) an effective absorption bandwidth 6.1 GHz (1.64 mm). This work establishes logical relationship between intrinsic absorption, offering method for permittivity.
