Abstract The Sb‐hybridization strategy enables the precise construction of p‐n heterojunctions, which significantly enhances electromagnetic wave (EMW) absorption performance by optimizing interface polarization. In this study, an innovative in situ ion‐exchange method is developed to implement Sb hybridization, establishing built‐in electric fields within CoS 2 /Sb S 3 @CNFs that amplify polarization relaxation loss. This structural design synergistically combines a carbon‐skeleton‐induced conductive network with magnetic loss mechanisms , ultimately yielding exceptional EMW absorber. optimized composite demonstrates remarkable attenuation capabilities, achieving minimum reflection (RL min ) −57.53 dB at mm and effective bandwidth (EAB max 7.28 GHz (covering X‐band (8–12 GHz) Ku‐band (12–18 GHz)). study not only provides novel for designing advanced absorbers but also highlights significance heterojunction engineering functional composites.

A novel adsorbent ZnAl–LDHs/SiO2 (ZA/SiO2) was prepared by blending urea mixture of ZnSO4 and Al2(SO4)3 while using SiO2 as a support form. The adsorption properties ZA/SiO2 for the removal toxic metal ions (Cu(II) Cr(VI)) from water were evaluated. By batch experiment method to investigate Cu(II) Cr(VI) solution treatment effect. sorption kinetics curves on L-shaped. What's more, solid concentration effect found in process kinetics. Langmuir Freundlich isotherm models used analyze data. results showed that conforms models. However, capacity compounds is greatly improved. 158 mg·g−1 176 mg·g−1, which 3.6 1.8 times ZnAl-LDHs (ZA), respectively.

Flexible supercapacitors have emerged as pivotal energy storage components in wearable smart electronic systems, owing to their exceptional electrochemical performance. However, the widespread application of flexible devices is significantly hindered by developmental bottleneck high-performance anode materials. In this study, a novel electrode composed surface-modified Fe2O3 nanoneedles uniformly coated with polypyrrole (PPy) film and anchored on Co-MOF-derived N-C nanoflake arrays (PPy/Fe2O3/N-C) designed. This composite electrode, grown situ carbon cloth (CC), demonstrated outstanding specific capacity, rate performance, mechanical flexibility, attributed its unique hierarchical 3D arrayed structure protective PPy layer. The fabricated PPy/Fe2O3/N-C@CC (P-FONC) exhibited an excellent capacitance 356.6 mF cm−2 (143 F g−1) at current density 2 mA cm−2. increased 20 cm−2, material preserved 278 (112 g−1). Furthermore, assembled quasi-solid-state Mn/Fe asymmetric supercapacitor, configured P-FONC negative MnO2/N-C@CC positive robust chemical stability notable flexibility. study sheds fresh light creation three-dimensional materials for highly efficient, systems.
