Multi-layer 2D material assemblies provide a great number of interfaces beneficial for electromagnetic wave absorption. However, avoiding agglomeration and achieving layer-by-layer ordered intercalation remain challenging. Here, 3D reduced graphene oxide (rGO)/MXene/TiO2/Fe2C lightweight porous microspheres with periodical intercalated structures pronounced interfacial effects were constructed by spray-freeze-drying microwave irradiation based on the Maxwell-Wagner effect. Such approach reinforced via defects introduction, skeleton, multi-layer assembly multi-component system, leading to synergistic loss mechanisms. The abundant 2D/2D/0D/0D heterojunctions in high density polarization charges while generating sites, resulting boosted polarization, which is verified CST Microwave Studio simulations. By precisely tuning nanosheets heterostructures, both impedance matching improve significantly. At low filler loading 5 wt%, rate exceeds 70%, minimum reflection (RLmin) -67.4 dB can be achieved. Moreover, radar cross-section simulations further confirm attenuation ability optimized microspheres. These results not only novel insights into understanding enhancing effects, but also constitute an attractive platform implementing heterointerface engineering customized hierarchical architectures.

Abstract Design and preparation of an efficient nonprecious cocatalysts, with structural features functionality necessary for improving photocatalytic performance semiconductors, remain a formidable challenge until now. Herein, the first time, novel CoP cocatalyst single‐atom phosphorus vacancies defects (CoP‐V p ) is synthesized coupled Cd 0.5 Zn S to build CoP‐V @Cd @CZS) heterojunctions photocatalysts via liquid phase corrosion method following by in suit growth process. The nanohybrids deliver attractive hydrogen production activity 2.05 mmol h −1 30 mg under visible‐light irradiation, which 14.66 times higher than that pristine ZCS samples. As expected, further enhances charge‐separation efficiency ZCS, addition improvement electron transfer efficiency, confirmed ultrafast spectroscopies. Mechanism studies based on density functional theory calculations verify Co atoms adjacent V play key role translation, rotation, transformation electrons H 2 O reduction. This scalable strategy focusing defect engineering provides new insight into designing highly active cocatalysts boost application.
