Abstract Defects and microstructures have been utilized to effectively modulate electromagnetic (EM) wave absorption for mitigating pollution stealth issues. However, precisely feasibly tailoring them still remains challenging. Here, by using a multilevel hollow cobalt sulfide embedded in heteroatomic sulfur (S) ‐doped carbon aerogel, preferential reaction strategy of modulating point defects via controllable S atoms migration is proposed improve the EM absorption. contribute creation structures Kirkendall effects, as well inducing lattice through doping. More significantly, mechanisms prioritizing formation over discovered, with low‐velocity atomic primarily microstructure interfacial polarization impedance matching, high‐velocity atom focused on introducing achieve conductive loss. The resulting aerogel exhibits an exceptionally maximum reflection loss −52.82 dB effective bandwidth 8.82 GHz, which far exceeds most currently reported materials. Experimental theoretical approaches, including microwave heating, Tesla interaction, first principles, far‐field simulation, are comprehensively employed verify its effect mechanism. Furthermore, combination excellent infrared self‐cleaning properties opens up potential applications complex environments.

Abstract Heterointerface engineering is presently considered a valuable strategy for enhancing the microwave absorption (MA) properties of materials via compositional modification and structural design. In this study, sulfur‐doped multi‐interfacial composite (Fe 7 S 8 /NiS@C) coated with NiFe‐layered double hydroxides (LDHs) successfully prepared using hydrothermal method post‐high‐temperature vulcanization. When assembled into twisted surfaces, NiFe‐LDH nanosheets exhibit porous morphologies, improving impedance matching, scattering. Sulfur doping in composites generates heterointerfaces, numerous sulfur vacancies, lattice defects, which facilitate polarization process to enhance MA. Owing controllable heterointerface design, unique structure induced multiple endowing Fe /NiS@C an enhanced MA capability. particular, minimum reflection loss (RL min ) value reached −58.1 dB at 15.8 GHz thickness 2.1 mm, broad effective bandwidth (EAB) 7.3 achieved 2.5 mm. Therefore, exhibits remarkable potential as high‐efficiency material owing synergistic effects processes, scatterings, structures, matching.

Cellulose aerogels, as a novel class of carbon-based materials, exhibit immense potential in the field microwave absorption (MWA) due to their biocompatibility, low density, unique porous structure, and tunable architecture. However, development multi-dimensional components with specialized heterogeneous structures, which are based on cellulose remains significant challenge. This 0D/1D/3D structural configuration facilitates electromagnetic properties favorable impedance matching. The Schottky contact at ZnO/Ni interface, particular, induces strong interfacial polarization, design results multiple heterointerfaces. Density functional theory (DFT) calculations reveal that barrier causes band bending, facilitating directed migration electrons interface formation an internal electric field, thus significantly accelerating multipolar relaxation process. As anticipated, CCMC/ZnO@Ni aerogel exhibits minimum reflection loss (RLmin) value -64.0 dB 13.9 GHz thickness 2.0 mm, its effective bandwidth (EAB) reaches 4.9 GHz. work gives valuable guidance inspiration for materials composed dimensional gradient holds great application wave (EMW) attenuation.
