Preparation and characterization of an effective microwave absorbent: RGO-MoS2-Fe3O4 nanocomposite

Reduced graphene oxide-molybdenum disulfide (RGO-MoS 2 ) loaded Fe 3 O 4 nanoparticles composite (RGO-MoS 2 -Fe 3 O 4 ) is prepared via two-step hydrothermal reaction. RGO-MoS 2 possesses three dimension architecture structures. This structure can prevent RGO and MoS 2 nanosheets restacked together...

Zusammenfassung:Reduced graphene oxide-molybdenum disulfide (RGO-MoS 2 ) loaded Fe 3 O 4 nanoparticles composite (RGO-MoS 2 -Fe 3 O 4 ) is prepared via two-step hydrothermal reaction. RGO-MoS 2 possesses three dimension architecture structures. This structure can prevent RGO and MoS 2 nanosheets restacked together and provide substrates for the Fe 3 O 4 nanoparticle decoration. The sizes of Fe 3 O 4 are in the range of 5–20 nm. As a microwave absorbent: the minimum reflection loss (R L ) value is -47.67 dB at 17.44 GHz when the thickness is only 1.5 mm. The absorption bandwidth (R L
