However, their catalytic activity and stability remain inadequate for practical applications. Here we implement an interfacial modulation strategy by coating cobalt oxide (e.g., Co3O4) nanocrystals with a single-metal-atom–modified, nitrogen-doped carbon (MNC) layer, and further optimize the interface between Co3O4 and MCN through single atom metal regulation. Across the series, Co3O4/MnNC exhibits a trend-like optimum, delivering overpotentials of 296 and 401 mV at 10 and 100 mA·cm–2, respectively, and showing excellent durability with only a 36 mV increase after 240 h at 10 mA·cm–2. Combining X-ray absorption fine structure (XAFS) characterization and density functional theory (DFT) calculations, the Co–N–Mn structure is identified as the active site, while the coating layer suppresses surface structural relaxation of Co3O4, thereby improving the structural stability. Moreover, in situ XAFS investigations confirm the formation of a stable Co–N–Mn interfacial structure under operational conditions. These results offer interfacial modulation as an effective route for high-performance, earth-abundant OER catalysts in acidic media.","PeriodicalId":225604,"journal":{"name":"Nano Research Energy","volume":"5 1","pages":"e9120215-e9120215"},"PeriodicalIF":0.0,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciopen.com/local/article_pdf/10.26599/NRE.2025.9120215.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147920074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employs 1 mol% N-(2-hydroxyethyl) succinimide (NHS) as a multifunctional electrolyte additive to address these issues. The carbonyl groups (C=O) in NHS can strongly coordinate with Zn atoms and water molecules, selectively adhering to the Zn anode surface to displace H2O, thereby suppressing parasitic reactions while simultaneously reducing water activity in the electrolyte. The NHS can regulate Zn2+ solvation by replacing water molecules in the primary solvation sheath, thereby further facilitating Zn2+ desolvation by reducing the number of bound water molecules. Additionally, the NHS on the anode surface enables a homogeneous Zn2+ flux, resulting in uniform zinc deposition. As a result, the NHS enables a ZnZn symmetric cell to achieve 7,500 h cycling at 1 mA·cm−2, and a ZnCu cell to maintain 99.8% Coulombic efficiency over 3200 cycles. The ZnV2O5 full cell retains 82.5% capacity after 7,000 cycles.

Interestingly, the optimal Quint-MMV-COF presents excellent electrocatalytic efficiency for S-S bond products (yields up to 99%) and H2 (~1.62 mmol·g–1·h–1) and can be readily recycled for 6 cycles. At the same time, 1.52 g product with a yield of ~92% can be obtained in the amplification reaction, showing much potential in industrial production.

However, seawater electrolysis for hydrogen production still faces numerous risks and challenges at present. This study focuses on a systematic investigation of FeNiCo-based high-entropy alloy (HEA) nanocatalysts supported on carbon skeletons. By precisely regulating the morphological structure of the carbon skeleton, a carbon support with a large specific surface area and abundant active sites can be obtained. Simultaneously, the elemental composition of the HEA nanoparticles is adjusted to optimize its seawater electrolysis performance. An energy-saving strategy of coupling the anode sulfur oxidation reaction (SOR) with the cathode hydrogen evolution reaction (HER) is employed to assist seawater electrolysis. In alkaline seawater, at a current density of 10 mA·cm−2, the overpotential of the HER is only 22 mV, and the overpotential of the oxygen evolution reaction (OER) is 264 mV. It also exhibits excellent performance in acidic seawater. In a two-electrode seawater electrolysis system, an applied voltage of 1.55 V is required to reach a current density of 10 mA·cm−2. More importantly, when using SOR to assist alkaline seawater electrolysis, the applied voltage is successfully reduced to 0.82 V.","PeriodicalId":225604,"journal":{"name":"Nano Research Energy","volume":"4 4","pages":"e9120196-e9120196"},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://file.sciopen.com/sciopen_public/1969967695992004609.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147919547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Manganese dioxide is studied as one kind of cathode material, however, it typically displays slow kinetics and unstable crystal structures. Defect engineering introduces active sites in MnO2, while metal ion doping increases material's molar mass, which offers rare zinc storage contribution. To find a feasible doping strategy with optimized oxygen vacancies is highly desirable. Herein, the incorporation of nitrogen-doped MnO2 (NMO) with lower electronegativity as the cathode enabled the realization of reversible aqueous zinc-ion batteries. The structural stability and electrochemical properties of NMO were enhanced by nitrogen doping. NMO exhibited a smaller charge transfer resistance than pristine MnO2 (279.6 Ω vs. 484.5 Ω). Cyclic voltammetry curves displayed that the incorporation of nitrogen doping could decrease the polarization, which provided a good basis for optimizing electrode kinetics. Specifically, the battery displayed a promising specific discharge capacity of 153.1 mAh·g–1 at 0.5 A·g–1 after 100 cycles. And at the current density of 1 A·g–1, the capacity retention of NMO after 1600 cycles was 1.72 times that of pristine MnO2.

Here, we report a charging-free redox flow battery for continuous high-power, low-grade heat harvesting based on thermosensitive crystallization-boosted TREC. Using molecular dynamics (MD) and density functional theory (DFT), we analyzed the mesoscopic intermolecular interactions, radial distribution, and solvation structure variations of [Fe(CN)6]3−/[Fe(CN)6]4− across varying temperatures. These insights elucidate the mechanism of thermosensitive crystallization evolution and its influence on entropy change during the thermodynamic cycle. By rationally adjusting redox activity at various temperatures, the system achieves an impressive temperature coefficient of −3.72 mV/K and a full-cell coefficient averaging –2.78 mV/K, exceeding the highest value of reported charging-free TRECs.

While many efforts have been made to enhance solar thermal conversion performance from materials design aspects, little attention has been given to the fundamental solar thermal gradient concept, which significantly affects local heating during evaporation. In this work, the polymer sponge evaporator was designed to control the solar thermal gradient by adding copper–carbon core–shell (Cu@C) nanoparticles with similar solar absorptance to understand the effect of solar thermal gradient or local heating on evaporation performance. The optimized solar evaporation can be 2.0 kg·m−2·h−1 under 1000 W·m−2 (one sun) with a Cu@C mass fraction of 0.5 wt.%, which was higher than that observed in cases with either higher or smaller Cu@C mass fraction. A too-small or large Cu@C mass fraction would enhance heat loss from the bottom or top parts, which was also confirmed by simulation results. Further outdoor water yield experiment showed that the optimized Cu@C mass fraction of 0.5 wt.% achieved the highest water collection (6.67 kg·m−2·d−1) compared with the other cases, such as 5.92 kg·m−2·d−1 for 0.1 wt.%, 5.29 kg·m−2·d−1 for 1 wt.%.
