Preparation of porous Fe₂O₃ nanorods-reduced graphene oxide nanohybrids and their excellent microwave absorption properties.

ABSTRACT: In this paper, α-Fe₂O₃ nanoparticles (NPs)-reduced graphene oxide (RGO), α-FeOOH nanorods (NRs)-RGO and porous α-Fe₂O₃ NRs-RGO could be selectively synthesized by hydrothermal method. The investigations indicated that the obtained α-Fe₂O₃ NPs, α-FeOOH NRs and porous α-Fe₂O₃ NRs were either attached on the surface of RGO sheets or coated uniformly by the RGO sheets. And the as-prepared nanohybrids exhibited excellent microwave absorption performance, which was proved to be ascribed to the quarter-wavelength matching model. The optimum reflection loss (RL) values for α-Fe₂O₃ NPs-RGO, α-FeOOH NRs-RGO and porous α-Fe₂O₃ NRs-RGO were ca. -32.3, -37.4 and -71.4 dB,
