In order to explore high efficiency microwave absorption materials, heteronanostructured Co@carbon nanotubes-graphene (Co@CNTs-G) ternary hybrids were designed and produced through catalytic decomposition of acetylene at the designed temperature (400, 450, 500 and 550 °C) over Co3O4/reduced graphene oxide (Co3O4/RGO). By regulating the reaction temperatures, different CNT contents of Co@CNTs-G ternary hybrids could be synthesized. The investigations indicated that the as-prepared heteronanostructured Co@CNTs-G ternary hybrids exhibited excellent microwave absorption properties, and their electromagnetic and microwave absorption properties could be tuned by the CNT content. The minimum reflection loss (RL) value reached approximately −65.6, −58.1, −41.1 and −47.5 dB for the ternary hybrids synthesized at 400, 450, 500 and 550 °C, respectively. And RL values below −20 dB (99% of electromagnetic wave attenuation) could be obtained over the as-prepared Co@CNTs-G ternary hybrids in the large frequency range. Moreover, based on the obtained results, the possible enhanced microwave absorption mechanisms were discussed in details. Therefore, a simple approach was proposed to explore the high performance microwave absorbing materials as well as to expand the application field of graphene-based materials.

“…[20][21][22][23][24][25][26][27][28] Hollow structures exhibit special physical and chemical properties due to their low density and large surface area, having attracted attention as candidates for microwave absorption in recent years. [29][30][31] Zhao et al prepared the hollow three-dimensional CuS hierarchical microspheres and the effective bandwidth was 3.0 GHz with absorber thickness of 1.1 mm. 32 Considering the outstanding properties of graphene as well as hollow structures, hollow structures/graphene hybrids would be very attractive for practical applications.…”

“…Metallic oxide may be candidates for EM wave attenuation at high temperature. [21][22][23][24][25][26][27][28] Nonetheless, it is difficult for them to achieve high-efficiency EM wave attenuation due to weak electrical properties. Searching for high-efficiency EM wave attenuation materials, therefore, is still a highly challenging task, which only becomes more difficult in view of the stabilization of attenuation at high temperature.…”

RSC Advances ARTICLE This journal is © The Royal Society of Chemistry 20xxJ. Name., 2013, 00, 1-3 | 1 The immense potential of electromagnetic wave attenuation materials for the applications in harsh dynamic environment has propelled much recent research and development. Here, we present the original observations on high-temperature electromagnetic properties and attenuation behavior of Bi0.8La0.2FeO3 at 323 -673 K. Bi0.8La0.2FeO3 exhibits high-efficiency and stable attenuation at dynamic temperature and frequency condition. With the increase of temperature, the attenuation capacity enhances, where the minimum reflection loss is less than -10 dB from 323 K to 673 K, and the best reflection loss reaches -54 dB at 573 K, which is 2.7 times of that of BiFeO3. With changing frequency, the effective reflection loss (≤ -10 dB) almost covers 3 GHz in the full tempera...
