? 2022 Elsevier B.V.BHPC (biomass hierarchical porous carbon) is a new microwave absorption material with extraordinarily low density, excellent dielectric loss, and a low environmental impact. In this paper, a Ni/BHPC composite is introduced, which were fabricated using a simple electroless plating method. When the NiSO4 concentration is changed, the electromagnetic characteristics and absorption performance are optimized. The Ni/BHPC composite material exhibits excellent absorption characteristics at a NiSO4 concentration of 0.2 mol/L. With a thickness of 2.7 mm, the RLmin is ?58.504 dB at 10.741 GHz. In the frequency range 8.221–12.4 GHz, with a thickness of 2.9 mm, this reflection loss (RL) is less than ?10 dB. These results indicate that incorporating Ni particles into the BHPC enhances its wave absorption efficiency. The research contributes to develop high-performance porous carbon microwave absorption materials from biomass.
