Fabrication of biomass-derived carbon decorated with NiFe2O4 particles for broadband and strong microwave absorption

Carbon materials derived from natural biomaterials are receiving increasing attention in recent years, due to their low cost, accessibility and renewability. In this work, a nano-porous carbon (PC)@NiFe2O4 magnetic composite has been prepared by a facile method from pomelo peels (PP) and its electro...

Zusammenfassung:Carbon materials derived from natural biomaterials are receiving increasing attention in recent years, due to their low cost, accessibility and renewability. In this work, a nano-porous carbon (PC)@NiFe2O4 magnetic composite has been prepared by a facile method from pomelo peels (PP) and its electromagnetic wave absorption properties have also been investigated in detail. Benefitting from the suitable impedance match, attenuation constant and unique hierarchically porous structure, the as-synthesized PC@NiFe2O4 composite displays enhanced microwave absorption capability compared to NiFe2O4 particles. The reflection loss (RL) of PC@NiFe2O4 composite is as high as −50.8 dB at 14.3 GHz and the absorption bandwidth (RL
