Hollow MoC/NC sphere for electromagnetic wave attenuation: direct observation of interfacial polarization on nanoscale hetero-interfaces

Abstract

Carbon-based composites with hetero-interfaces is a group of promising electromagnetic wave absorbing materials (EWAMs) for its excellent dielectric loss. For developing this kind of EWAM, in situ constructing hetero-interfaces and...

A One-Stone-Two-Birds Strategy to Functionalized Carbon Nanocages

“…In the Raman spectrum of MoC/NCNCs, two peaks appear at 1350 and 1590 cm –1 , which are assigned to disordered sp 3 carbon (D band) and graphitic sp 2 carbon (G band), respectively (Figure S2b). , In addition, the structures of MoC/NCNCs were studied by XRD measurement. The broad peak at 2θ = 24.6° in the XRD pattern is ascribed to graphite carbon, while the peaks at 2θ = 36.2°, 43.2°, 61.2°, and 73.4° can be indexed as MoC (Figure S3a).…”

Recent advancements in the electromagnetic interference shielding performance of nanostructured materials and their nanocomposites: a review

“…559 The enhanced microwave absorption performance has also been reported for reduced graphene oxide/Fe 2 O 3 hollow microspheres coated sponges, 560 porous and hollow CoNi@C microspheres, 561 hollow spherical MoS 2 @Fe 3 O 4 -GNs ternary composites, 562 3-D mesoporous carbon spheres modified with ZnO nanoparticles, 563 lightweight MWCNT/hollow mesoporous carbon/WPU composite, 564 and hollow Fe 3 O 4 onto graphene foam nanocomposites. 565 Very recently, Huang et al 566 fabricated hollow MoC-incorporated N-doped carbon as a promising material for electromagnetic wave attenuation. It was inferred that Mo defects in MoC contributed to the impedance matching through the hollow shell and accelerated the charge transfer and exhibited enhanced interfacial charge, displaying an enhanced interfacial charge polarization.…”

A star-shaped polyimide covalent organic framework for high-voltage lithium-ion batteries

“…1,2 Considering that carbon emission and environmental protection have been listed as the most important topics for humans, developing environmentally friendly and sustainable electrode materials is highly desired. Among various materials, 3–7 organic electrode materials featuring abundant sources, high structural flexibility, and low toxicity have attracted more and more attention. 8,9 Moreover, organic electrode materials composed of light elements (such as C, H, O, and N) can be obtained from renewable resources and recycled with low environment footprint.…”
