Fe3O4 nanoparticles anchored on hierarchical porous carbon derived from egg white for efficient microwave absorption performance

Synthesis of hollow core–shell ZnFe2O4@C nanospheres with excellent microwave absorption properties

“…Many researchers have demonstrated that this scheme is feasible to improve microwave absorption performance. Deng 15 synthesized FeCoNiZn alloy@carbon nanocomposite with a unique heterostructure, which owned the RL max of À54.46 dB at 16.65 GHz and the effective bandwidth reaches 4.19 GHz under the thickness of 1.62 mm. Gu 16 prepared Fe 3 O 4 /HPC (hierarchical porous carbon) by a facile strategy.…”

Gu 16 prepared Fe 3 O 4 /HPC (hierarchical porous carbon) by a facile strategy. Fe 3 O 4 /HPC composite presented a signicant improvement of the microwave absorption compared with a single HPC frame when the Fe 3 O 4 lling content is 40%, the RL max value is up to À57.8 dB at 7.36 GHz with a thinner thickness of 3.48 mm, and the bandwidth lower than À10 dB ranging from 11.92 GHz to 17.92 GHz.…”
