| 摘 要： | 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 d B 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 ...
