Thickness-controllable synthesis of MOF-derived Ni@N-doped carbon hexagonal nanoflakes with dielectric-magnetic synergy toward wideband electromagnetic wave absorption

Heteroatom nitrogen doping and morphology control have been considered as the effective approaches for improving electromagnetic wave (EMW) absorption ability of carbon-based absorbers. Herein, by controlling the adding dosage of pyridine, thickness controllable MOF-derived [email protected] carbon ([email protected]) hexagonal nanoflakes presented increased content of doped N atoms and tunable morphology from nanorods-, nanoparticles- to...
