Bimetallic Hybridization Induced Multi‐polarization Loss in Multiphase Solid Solution for Electromagnetic Wave Absorption †

Comprehensive Summary Aiming at the polarization loss bottleneck in electromagnetic wave (EMW) absorbing materials, we propose a new bimetallic hybrid strategy towards multiphase solid solutions to increase multiple polarization losses. Assisted by polydopamine (PDA) as crystalline phase inducer, Mo/W substances were anchored in situ on carbon networks. As a result, a carbon‐supported MoC 1– x /WC/W 2 C/WC 1– x heterostructure was formed. This process leads to Mo migration and W occupying vacancies, resulting in vacancy/substitution defects. Simultaneously, Li + is inserted into the solid solution to form an interstitial structure. Due to the synergistic effect of multiple polarization losses, the Mo2W‐900…
