Interface Engineering of Heterogeneous NiSe 2 ‐CoSe 2 @C@MoSe 2 for High‐Efficient Electromagnetic Wave Absorption
Yancheng Institute of Technology
Abstract
Abstract Optimization of components and micromorphology regulation are shown to be effective in boosting electromagnetic wave absorption (EMWA). One approach to achieve this enhancement is by utilizing the polarization effects of heterogeneous interfaces. Herein, NiSe 2 ‐CoSe 2 @C@MoSe 2 composites derived from NiCo‐MOF‐74 are fabricated via a facile selenization reaction and subsequent hydrothermal method. By varying the mass ratios of NiSe 2 ‐CoSe 2 @C and MoSe 2 , a series of NiSe 2 ‐CoSe 2 @C@MoSe 2 composites with hierarchical flower‐like core–shell structures are obtained. The EMWA properties of the composites display a trend of initially increasing and then decreasing with the increasing content of MoSe…
