Abstract Construction of built‐in electric field (BIEF) in nanohybrids has been demonstrated as an efficacious strategy to boost the dielectric loss by facilitating oriented transfer and transition charges, thus optimizing electromagnetic wave absorption property. However, specific influence BIEF on interface polarization needs explore thoroughly strength should be further augmented. Herein, several systems incorporated Mott–Schottky heterojunctions hollow structures are designed constructed, where bimetallic zeolitic imidazolate framework employed derive Cu‐ZnO heterojunctions, hierarchical enriched introducing structure reduced graphene oxide. The well‐established “double” verified theoretical calculation engineering can regulate conductivity, enhance relaxation effectively. Especially, there always coexisted both enhanced charge separation reversed distribution this BIEF, boosting polarization. Attributing synergy well‐matched impedance amplified loss, obtained hybrids exhibited superior (reflection −46.29 dB ultra‐wide effective bandwidth 7.6 GHz at only 1.6 mm). This work proves innovative model for dissecting mechanisms pioneers a novel advanced absorbers through enhancing BIEF.

Abstract Thermochemical conversion is a highly effective method for upgrading organic solid wastes into high‐value materials, contributing to carbon neutrality and peak, emission goals. It also serves as pathway develop energy‐efficient electromagnetic wave absorbing (EMWA) materials. In this study, fish skin successfully in situ nitrify Prussian Blue Fe 3 N under external thermal driving condition, resulting high saturation magnetization utilized. The N@C demonstrates outstanding EMWA property, achieving minimum reflection loss of −71.3 dB. Furthermore, by introducing cellulose nanofiber, portion the iron nitride transformed carbide, C/Fe N@C. This composite exhibits enhanced properties owing wider local charge redistribution stronger electronic interactions, an absorption bandwidth ( EAB ) 6.64 GHz. Electromagnetic simulations first‐principles calculations further elucidate mechanism, maximum reduction value radar‐cross section reached 37.34 dB·m 2 . design multilayer gradient metamaterials demonstrated ultra‐broadband 11.78 paper presents efficient strategy atomic‐level biomass waste utilization prepare N, provides novel insights between metal nitrides carbides, offers promising direction development advanced
