MOFs-Derived Hollow Co/C Microspheres with Enhanced Microwave Absorption Performance

TL;DR: In this paper, the pyrolysis temperature plays an important role in determining the electromagnetic properties of these hollow Co/C microspheres, where high pyrolysis temperature will increase relative complex permittivity and decrease relative complex permeability.
Journal ArticleDOI

Core-shell FeCo@carbon nanoparticles encapsulated in polydopamine-derived carbon nanocages for efficient microwave absorption

TL;DR: In this paper, the authors used dopamine (DA) on their surface and then converted the precursor into desirable FeCo alloy/carbon composites to suppress the microstructure collapse of FeCo PBAs during high-temperature pyrolysis, resulting in a unique hierarchical configuration of coreshell FeCo@C nanoparticles encapsulated in PDA-derived carbon nanocages.
Journal ArticleDOI

Pea-like Fe/Fe3C Nanoparticles Embedded in Nitrogen-Doped Carbon Nanotubes with Tunable Dielectric/Magnetic Loss and Efficient Electromagnetic Absorption

TL;DR: There is an effective balance between dielectric loss and magnetic loss, which accounts for a very stable attenuation ability when the pyrolysis temperature range changes from 600 to 700 °C, which may render Fe/Fe3C@NCNTs composites as a novel kind of MAMs in the future.
Journal ArticleDOI

Prussian blue analogues derived magnetic FeCo alloy/carbon composites with tunable chemical composition and enhanced microwave absorption.

TL;DR: Electromagnetic analysis reveals that the excellent microwave absorption of sample S4 benefits from its preferable matching of characteristic impedance and good attenuation ability toward incident electromagnetic waves, which provides new insight into the fabrication of carbon-based magnetic composites with enhanced microwave absorption.
Journal ArticleDOI

Waxberry-like hierarchical Ni@C microspheres with high-performance microwave absorption

TL;DR: In this article, the effects of pyrolysis temperature on the microstruture, carbon content, relative graphitization degree, magnetic properties, and electromagnetic parameters were carefully investigated.
