Biomass-based porous carbon composites have received widespread attention in
microwave absorption field due to sustainable sources, unique micro-nano structure, low
cost. Nevertheless, it is still a huge challenge to construct biomass-derived microwave
absorbers with reasonable structure and multi-component magnetic/dielectric structures in
order to satisfy the conditions of advanced electromagnetic wave absorption materials.
Herein, CoNi-metal-organic framework (MOF) was grown in-situ on the wood, and CoNi …
