Abstract
Abstract The electron migration polarization is considered as a promising approach to optimize electromagnetic waves (EMW) dissipation. However, it is still difficult to realize well‐controlled electron migration and elucidate the related EMW loss mechanisms for current researches. Herein, a novel Fe x N@NGC/Ce system to construct an effective electron migration model based on the electron leaps among the 4 f /5 d /6 s orbitals of Ce ions is explored. In Fe 4 N@NGC/Ce SA+Cs+NPs , Ce single‐atoms (SA) mainly represent a +3 valence state, which can feed the electrons to Ce 4+ of clusters (Cs) and CeO 2 nanoparticles (NPs) through a conductive network under EMW, leading to the electron migration polarization.…
