The construction of hierarchical structures has been demonstrated to be an effective method for achieving high-performance microwave absorption. In this study, a flower-like MoS2 nanosheet-coated tubular carbon composite with an average diameter of approximately 560 nm was synthesized via a straightforward ion-exchange and pyrolysis strategy. The growth of MoS2 nanosheets, the presence of heterojunction surfaces, and the construction of the hollow structure collectively enhance the dielectric loss of the material, thereby optimizing the microwave absorption properties of the material. The C@MoS2 nanocomposite demonstrates a minimum reflection loss of -66.8 dB and an effective absorption bandwidth of 4.8 GHz when the thickness is only 1.6 mm. This work presents a synergistic strategy for the design of layered hollow structures. [ABSTRACT FROM AUTHOR] |
