MoS₂ nanoparticle/activated carbon composite as a dual-band material for absorbing microwaves.

ABSTRACT: In the search for novel high-performance microwave (MW) absorbers, MoS₂ has shown promise as a MW-absorbing material, but its poor impedance matching limits its applications. Herein, a facile hydrothermal method was used to produce a composite consisting of activated carbon (AC) derived from waste biomass and in situ-grown MoS₂ nanoparticles. Its microwave absorption properties were examined in the 2-18 GHz frequency range, and FESEM and HRTEM images confirmed the formation of MoS₂ nanoparticles on the AC. The maximum reflection loss (RL_max) for the MoS₂/AC composite was -31.8 dB (@16.72 GHz) at 20 wt% filler loading. At 50 wt% filler loading, the MoS₂/AC (MAC50) composite exhibited unique dual-band absorption charact
