Construction of 1D Heterostructure NiCo@C/ZnO Nanorod with Enhanced Microwave Absorption

Nano-Micro Letters, Journal Year: 2021, Volume and Issue: 13(1)

Published: Aug. 16, 2021

Layered double hydroxides (LDHs) have a special structure and atom composition, which are expected to be an excellent electromagnetic wave (EMW) absorber. However, it is still problem that obtaining EMW-absorbing materials from LDHs. Herein, we designed heterostructure NiCo-LDHs@ZnO nanorod then subsequent heat treating derive NiCo@C/ZnO composites. Finally, with the synergy of dielectric loss magnetic loss, outstanding absorption performance could achieved reflection - 60.97 dB at matching thickness 2.3 mm, widest bandwidth 6.08 GHz was realized 2.0 mm. Moreover, this research work provides reference for development utilization LDHs in field microwave can also provide ideas design layered structural absorbers.

2D MXene Nanomaterials: Synthesis, Mechanism, and Multifunctional Applications in Microwave Absorption

Small Structures, Journal Year: 2022, Volume and Issue: 3(10)

Published: July 16, 2022

MXene nanomaterials stand out among 2D and have been extensively studied by researchers because of their unique layered structure, chemical diversity, outstanding physical properties. In recent years, materials rapidly opened the market for electromagnetic interference shielding technology due to excellent wave absorption (EMA) capability. However, so far, compared with development (EM) technology, there is still much room in construction MXenes application absorption. Herein, strategies, conversion mechanism, applications are reviewed. Through meticulous material design an interdisciplinary approach, expected become one smart tunable absorbers, scenarios will also broader.

Multiphase Molybdenum Carbide Doped Carbon Hollow Sphere Engineering: The Superiority of Unique Double‐Shell Structure in Microwave Absorption

Small, Journal Year: 2022, Volume and Issue: 19(6)

Published: Nov. 27, 2022

In order to achieve excellent electromagnetic wave (EMW) absorption properties, the microstructure design and component control of absorber are critical. this study, three different structures made Mo2 C/C hollow spheres prepared their microwave behavior is investigated. The double-shell consisting an outer thin shell inner rough thick with multiple EMW loss mechanisms exhibit good properties. further improve MoC1-x /C crystalline phases molybdenum carbide optimize capability materials. Finally, α-phase have best When filling 20 wt.%, minimum reflection at 1.8 mm -50.55 dB effective bandwidth 2 5.36 GHz, which expected be a characteristics "thin, light, wide, strong".
