Abstract The novel three-dimensional (3D) co-doped carbon foam was fabricated via a facile hydrothermal and subsequent pyrolysis process using fish skin as carbon precursor. The fish-derived carbon foam (CFs) obtained at 650 °C (CFs-650) possesses large specific surface area of 1369.3 m2/g with natural inherited micropore-dominate porosity. Moreover, the heteroatoms O and N in the fish skin are uniformly planted into the carbon frameworks, which is highly advantageous for the attenuation of microwave energy. The unique architecture endows the 3D carbon foam with impressive microwave absorbing property. Especially, the broadest bandwidth (RL
