However, the NO2RR involves multistep electron transfer and complex intermediates, rendering the achievement of high NH3 selectivity a major challenge. In this contribution, heterostructured Cu2O/NiO nanoflowers are explored for incorporating the advantages of dual active sites as a highly active and selective NO2RR catalyst. Combined theoretical calculations and in situ FTIR/EPR spectroscopy analysis, it is revealed the synergistic effect of Cu2O and NiO to promote the NO2RR energetics of Cu2O/NiO heterostructure electrocatalyst through a tandem catalysis pathway, where Cu2O activates the initial absorption and deoxygenation of NO2− for boosting *NO formation, while the generated *NO on Cu2O is then transferred on NiO substrate with abundant active hydrogen for NH3 conversion. Moreover, the heterostructure formation enhances *H retention capacity, promoting *H consumed in NO2RR and inhibiting inter-*H species binding. As a result, Cu2O/NiO equipped in a flow cell displays a superior NH3 yield rate of 128.2 mg h−1 cm−2 and Faradaic efficiency of 97.1% at a high current density of −1.25 A cm−2. Further, this designed tandem system is proven to be adaptable for other electrochemical NH3 production reactions including NO3− reduction.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"7 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the low-temperature nitridation process for synthesizing the permanent magnetic Fe16N2 phase, a stable soft magnetic Fe4N phase tends to form on the surface of particles. Consequently, the porous structured Fe16N2/Fe4N composites composed of nano-units are prepared by spray pyrolysis and nitriding processes. The microwave-absorbing mechanisms of permanent/soft magnetic composite iron nitride with porous structure has been elucidated by analyzing the microstructure and electromagnetic properties of samples with varying contents of permanent and soft magnetic materials. The composite of permanent and soft magnetic materials not only creates a heterogeneous interface but also generates a magnetic exchange coupling effect, which improves the impedance matching and increases the interface polarization and dipolar polarization. Eventually, through the coordinated action of excellent dielectric and magnetic loss, good microwave absorption properties are achieved: the minimum reflection loss (RLmin) is −48.27 dB and the widest effective absorption bandwidth (EABmax) is 4.08 GHz with the matching thickness of 1.3 mm. This study provides new insight for further exploration of the application of nano-magnetic materials in the field of microwave absorption.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"6 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143640949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, a novel strategy is provided that utilizes the sperimagnetism of NiFeTb to achieve current-induced field-free magnetization switching with high efficiency and controllable chirality. The critical current density required for field-free magnetization switching is as low as 2.8 × 106 A cm−2, an order of magnitude lower than that in conventional heavy metal-based magnetic heterostructures. The ultralow critical current density is attributed to the exceptional soft magnetism, the nucleation-dominant switching characteristic of NiFeTb, and the strong spin Hall effect associated with the large spin-orbital coupling of Tb 4f electrons. Notably, the switching chirality can be designed by manipulating the history of the in-plane magnetic field. The field-free and chirality-controlled magnetization switching in NiFeTb is facilitated by the symmetry-broken sperimagnetic structural arrangement. Utilizing the rich intermediate resistance states and non-volatility of the device, neural network computation is simulated.

Conventional in-plane structure leads to short circuit and less participated electro-active sites in the redox process. However, out-of-plane heterostructure array provides rapid charge transport across vertically arranged nanoflakes, and forms less heat pockets due to less contact area between vertically arranged ensembles and in-plane nanoflake, making them suitable for advanced energy storage applications. Here, the energy storage performances of AISC based on out-of-plane heterostructure array is studied, which provides large surface area with ample active sites for rapid charge transport at the surfaces of vertically arrayed nanoflakes. The developed electrode material achieves a high specific capacitance of 555.6 F g−1 and capacitance retention of 82.3% after 5500 cycles. The assembled quasi-solid-state supercapacitor achieves high energy-power densities, and significant capacitance retention after 5000 cycles. The assembled device can illuminate different colored LEDs and power the scientific calculator. Importantly, the developed heterostructure array can dissipate heat and inhibit short circuit due to limited overlap between 2D CuSe ensemble and 2D WS2 nanoflake.

Herein, we systematically screen Sb2S3 for use as a PEO-based solid-state electrolyte (PSE) additive through theoretical calculations, and in situ construct a highly stable solid electrolyte interphase (SEI) enriched with Na2S and Na3Sb. This SEI, characterized by its low reduction reaction activity, high ionic conductivity, and strong Na affinity, significantly inhibits interfacial side reactions, accelerates ion transport, and facilitates smooth Na+ deposition. Moreover, the incorporation of Sb2S3 effectively enhances the mechanical robustness, ionic transference number, and ionic conductivity of the composite solid-state electrolyte film (Sb2S3@PSE), thereby mitigating the sodium dendrites formation. Consequently, remarkable electrochemical performances for the Sb2S3@PSE symmetric battery (achieving 5200 h at 0.1 mA cm−2, 520 times longer than that of pristine PSE), and the Na3V2(PO4)3|Sb2S3@PSE|Na full battery with high-capacity retention of 91% after 1000 cycles, are demonstrated.

Here, a catalytic system inspired is designed by the desert-beetle's hydrophilic/hydrophobic patterned back, a natural structure capable of condensing and transporting fog droplets. This catalytic system is composed of superaerophobic (SAB) electrocatalytic catalyst dots surrounded with superaerophilic (SAL) coating, which can efficiently enhance the gaseous and dissolved H2 mass transfer to achieve exceptional HER performance.

By controlling the oxygen partial pressure during synthesis, enhanced cycle stability is achieved without compromising the capacity of this unique structure.

These electrodes achieve 85.08% capacity retention at 2 C/0.1 C, demonstrating excellent rate performance. Comprehensive diffraction and microscopy analyses identify secondary particles with Li-excess structures on their surfaces (characterized by larger primary particles) and stoichiometric structures in the core (featuring smaller primary particles). This dual-gradient structure enhances performance by suppressing surface reactions and stabilizing the bulk. Furthermore, the electrodes retain pristine microstructure during electrochemical cycling, minimize lattice contraction (3.86%), and suppress H2-to-H3 transitions.
