Abstract Currently, facing electromagnetic protection requirement under complex aqueous environments, the bacterial reproduction and organic dye corrosion may affect composition micro‐structures of absorbers to weaken their properties. To address such problems, herein, a series CoFe 2 O 4 @BCNPs (cobalt ferrite @ bio‐carbon nanoparticles) composites are synthesized via co‐hydrothermal calcining process. The coupling magnetic cobalt dielectric derived from Apium can endow composite multiple absorption mechanisms matched impedance for effective microwave absorption, attaining bandwidth 8.12 GHz at 2.36 mm an intensity −49.85 dB 3.0 mm. Due ROS (reactive oxygen species) stimulation ability heavy metal ions ferrite, realizes excellent antibacterial efficiency 99% against Gram negative bacteria Escherichia coli . Moreover, loose porous layer surface stacked promote adsorption methylene blue subsequent eliminating, high removal rate 90.37% be also achieved. This paper offers new insight rational design composite's component micro‐structure construct multi‐functional absorber satisfying demand in complicated environments.
