Atomically Dispersed Ni Single-Atoms Anchored on N-Doped Graphene Aerogels for Highly Efficient Electromagnetic Wave Absorption
-
Abstract
Uniformly dispersed nickel single atoms (SAs) are experimentally prepared on ultralight N-doped graphene aerogels (Ni-SA@NRGA). The experimental results show that Ni-SAs in graphene aerogels can improve the conduction, polarization losses, and impedance matching properties of the Ni-SA@NRGA. As a result, the minimum reflection loss (RL,min) of Ni-SA@NRGA is −49.46 dB with a matching thickness of 2.0 mm and the broadest efficient absorption bandwidth is 3.12 GHz at a low thickness of 1.5 mm. Meanwhile, even with a matching thickness of 1.2–2.0 mm, the RL,min value of Ni-SA@NRGA can reach −20 dB. The current study demonstrates the significance of incorporating metal single atoms into graphene aerogel for electromagnetic wave absorption. -
