Abstract High‐performance microwave absorption materials (MAM) are often accompanied by synergistic effects of multiple loss mechanisms, but the contribution share various mechanisms has been neglected to provide a template and reference for design MAM. Here, highly conductive 2D structure is designed through functional group‐induced modulation strategy, composite L‐Ni@C can reach an effective bandwidth 6.45 GHz at 15% fill rate, with maximum efficiency 99.9999%. Through layer‐by‐layer analysis mechanism, it found that strong originates from polarization heterogeneous interface. The movement space charge between two‐phase interface forms interfacial electric field, in situ doping nitrogen cleverly achieved introduction amino groups, which significantly enhances rate transfer greatly facilitates electron migration polarization. motion law field also simulated using COMSOL simulation software illustrate mechanism interfaces.

The electrocatalytic technique, as an efficient energy storage and conversion technology, has attracted significant attention to address exhaustion environmental pollution. Usually, the activity selectivity of reactions are largely dominated by dynamic process occurring on electrocatalysts. Therefore, high-performance electrocatalysts, which can dominate pathway barrier reactions, great significance for advancement technique. Metal-organic frameworks (MOFs), emerging crystalline porous materials, present structural component advantages including well-defined structure, high surface area, large porosity, diverse components, easy tailorability, demonstrating fantastic potential precise fabrication In this Review, strategies in electrocatalysts based MOF-related materials specifically introduced from aspects catalytic site design microenvironment modulation around sites. Furthermore, representative progress achieved various applications employing MOF-based is systematically summarized, with special emphasis MOFs performance optimization. Finally, remaining challenges future perspectives further highlighted.

Abstract New types of metal–organic framework (MOF) materials have great potential in solving the current global dilemma on energy, environment, and medical care. Herein, based two kinds biomolecule‐MOFs (Bio‐MOFs) with favorable biocompatibility degradation‐reconstruction characteristics, we established a self‐powered muti‐functional device to achieve an efficient broad‐spectrum environmental energy collection biomedical applications. Combining Zn(II) carnosine‐based Zn‐Car_MOF possessing high piezoelectric response ( d 33 = 11.17 pm V −1 ) patterned polydimethylsiloxane (PDMS) film, tribo‐piezoelectric hybrid nanogenerator (TPHG) is constructed synergy output triboelectric effects. The Zn‐Car_TPHG demonstrates performance (131 at 100 kPa) wide range pressure (1 Pa–100 kPa), applications sensors. To expand application wearable device, conductive hexagonal prism MOF (Cu 3 (2,3,6,7,10,11‐hexahydroxytriphenylene) 2 (Cu‐HHTP)) synthesized employed load thymol (Thy). Cooperating Zn‐Car_TPHG, resulting Cu‐HHTP/Thy can ROS (singlet oxygen 1 O hydroxyl radical (·OH)) generation drug synergistic sterilization effect (efficiency ≥ 98%). In word, flexible Bio‐MOFs sustainable environmentally friendly, fields collection, biosensors, antibacterial.

Abstract Developing highly active and stable electrocatalysts for hydrogen production at industrial current densities is pivotal to give an impetus carbon neutrality. Recently, metal–organic frameworks (MOFs) with large surface area adjustable structures have become a class of promising alternative electrocatalysts, while their low conductivity poor stability limit widespread applications. Here, modified strategy proposed stabilize modulate Ruthenium (Ru) species including Ru single atoms (Ru SAs) nanoparticles NPs) on MOFs enhanced evolution reaction (HER). Benefiting from the strong interaction between MOFs, synthesized NiFeRu SA+NP ‐DOBDC (DOBDC: 2,5‐dioxido‐1,4‐benzenedicarboxylate) exhibits extraordinary HER performance overpotentials 25 271 mV 10 1000 mA cm −2 , respectively. Meanwhile, it enables robust high density 1 A over 300 h. Remarkably, assembled anion exchange membrane (AEM) electrolyzer realizes voltage alkaline water electrolysis. In situ analyses demonstrate that optimized H 2 O adsorption dissociation, theoretical calculations indicate SAs NPs accelerate Volmer‐Heyrovsky pathway, synergistically promoted performance.
