en This link goes to a English section zh This link goes to a Chinese section Aqueous Zn-ion batteries (AZIBs) are expected to become one of the most promising candidates for large-scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot-peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)-textured crystal planes while inducing grain refinement. The SP process effectively eliminates the surface passivation layer and structural defects, enhances the mechanical properties and corrosion resistance of the electrode surface, and provides abundant active sites for Zn nucleation. This promotes homogeneous and smooth deposition of zinc and ensures a uniformly distributed electric field, thereby suppressing dendrite growth and reducing side reactions. Consequently, the SP-treated Zn (SP-Zn) anode enables a symmetric cell that exhibits impressive reversibility and stable cycling for over 5000 h at 2 mA cm −2 , and an SP-Zn||MnVO full cell delivers 81% capacity retention after 2000 cycles at 5 A g −1 . This simple and cost-effective SP strategy offers a practical approach to fabricating high-performance Zn metal anodes, providing a scalable strategy for practical AZIB applications. 摘要 en This link goes to a English section zh This link goes to a Chinese section 水系锌离子电池(AZIBs)有望成为大规模储能领域最具前景的候选方案之一,但其发展受限于不可控的枝晶生长和寄生反应。本研究提出了一种简单的机械喷丸(SP)处理方法,对商用锌箔进行重构,以诱导高度暴露的(002)织构晶面,同时实现了晶粒细化。SP工艺有效去除了表面钝化层和结构缺陷,改善了电极的力学和耐腐蚀性能,并为锌成核提供了丰富的活性位点。可有效这促进锌的均匀沉积,确保了电场的均匀分布,从而抑制了枝晶生长并减少副反应。结果表明,经SP处理的锌(SP-Zn)负极组装的对称电池在电流密度为2 mA cm − 2 的测试条件下表现出优异的可逆性和稳定性,循环时间超过了5000小时,SP-Zn||MnVO全电池在5 A g −1 的测试条件下循环2000次后容量保持率达81%。该简便且低成本的SP策略为制备高性能锌金属负极提供了一种实用途径,为AZIBs的实际应用提供了一种可规模化的解决方案。

The valence electron configuration largely determines the performance of functional materials, in which different electron spin and orbital occupancy would induce diverse phenomena. Herein, the study of 3d electronic configuration dominant gas sensing selectivity is presented. Utilizing ultrafast Joule heating, transition metal spinels XCr 2 O 4 (X = Co, Ni, Zn) have been synthesized and consistently exhibit sensing selectivity toward xylene gas. The e g empty orbitals of Cr 3+ 3 d 3 (t 2g 3 e g 0 ) tend to overlap with the π orbitals of xylene molecules, achieving stable xylene adsorption and electron transfer and thus presenting remarkable xylene gas sensing selectivity. The valence electron configurations of 3 d 7 , 3 d 8 and 3 d 10 for Co 2+ , Ni 2+ and Zn 2+ result in a progressively lower response to xylene gas. This valence electron configuration perspective is experimentally supported by gas sensing selectivity of XFe 2 O 4 (X = Co, Ni, Zn) toward acetone molecules, in which the electronic orbital configuration of Cr 3+ 3 d 3 of B sites is replaced by Fe 3+ 3 d 5 . Theoretically, density functional theory (DFT) calculations based on adsorption energy and charge density difference confirm the strong adsorption of xylene at Cr 3+ sites and efficient electron transfer from xylene to Cr sites.

Trace Ag (Ag/Cu = 0.001) significantly enhanced Cu-Zn catalyzed CO 2 hydrogenation. • STY MeOH of Cu-Zn-Ag 0.001 was 467.8 g·kg −1 ·h −1 , 1.82 times higher than Cu-Zn. • Ag promotes oxygen vacancy formation around active sites at the Cu-ZnO interface. • Methanol synthesis follows the formate pathway with Ag lowering energy barriers. The methanol synthesis from catalytic CO 2 conversion has emerged as an attractive strategy for carbon valorization and sustainable energy generation. However, the catalytic efficiency of conventional Cu-Zn-based catalysts remains far from satisfactory. Herein, a Cu-Zn-Ag catalyst, synthesized via a facile co-precipitation method, exhibited a significantly improved methanol production activity compared with Cu-Zn catalysts. Notably, a trace amount of Ag doping (the Ag/Cu molar ratio was 0.001) could significantly elevate the methanol generation, with its space-time yield increasing from 258 ± 17 to 468 ± 23 g MeOH ·kg cat −1 ·h −1 , an increase of 1.82 times, while further increasing Ag doping would lead to reduced activity. Structural characterizations confirmed the Ag presence, being doped in the Cu lattice, and Ag doping was significantly beneficial to oxygen vacancy formation, which was deemed the active sites for methanol formation. The detailed reaction pathway (formate pathway) for methanol synthesis was also investigated based on density functional theory (DFT) calculations, where Ag doping lowered the energy barriers. This work elucidates the mechanism of Ag doping in Cu-Zn catalysts and provides key insights into the reaction mechanism of CO 2 hydrogenation to methanol, highlighting its potential for sustainable methanol synthesis.

Under
air operation, Sr-containing perovskite cathodes lose activity
mainly because the surface Sr species readily react with CO 2 , rather than because the intrinsic Co/Fe redox centers are insufficiently
active. A mild acid treatment was introduced to selectively regulate
the surface A-site environment of perovskite oxides, with the aim
of suppressing Sr-derived carbonation while retaining the perovskite
backbone. The mild acid treatment preferentially regulates Sr-related
surface species and partially reconstructs the outermost A-site coordination
environment, while the long-range perovskite framework remains largely
retained. Such surface A-site modification is accompanied by local
charge rebalancing, a shifted electronic state of Co/Fe species, and
a higher population of catalytically relevant oxygen-deficient sites,
which collectively accelerate oxygen reduction and oxygen evolution
reaction kinetics. Benefiting from the reconstructed surface chemistry,
the optimized catalyst delivers faster ORR/OER kinetics and, when
used in a rechargeable zinc-air battery, affords an open-circuit voltage
of 1.50 V, a peak power output of 102.66 mW cm –2 , and a discharge capacity of 805 mAh g –1 . Under
ambient-air operation, the device sustains long-term cycling beyond
300 h, which is consistent with the substantially alleviated carbonate
accumulation on the catalyst surface. This work highlights the critical
role of A-site chemical stability in designing carbonation-resistant
perovskite air cathodes and provides an effective strategy for developing
durable bifunctional oxygen electrocatalysts for practical metal-air
batteries.

While morphological control in metal–organic frameworks (MOFs) has been widely explored, the extension of this concept to compositional engineering and precise anisotropic growth in high-entropy systems has only recently emerged. Herein, we present the first synthesis of one-dimensional single-crystal HE-MOF-74 nanorods (comprising Co, Fe, Ni, Zn, and Mo) via a dual strategy, where zinc-directed anisotropic growth occurs exclusively on a graphene oxide support. In situ Raman spectroscopy combined with molecular probe electroanalysis and DFT analysis reveal two simultaneous catalytic pathways. (i) The oxophilic Mo promotes the adsorbate evolution mechanism (AEM) with Ni centers (Ni–Ni*-Mo), (ii) Zn enhances the covalency of the M–O bonds, specifically favoring Fe–O/Co–O covalency to activate the lattice-oxygen-mediated mechanism (Co/Fe–O*-Zn). This synergistic dual-pathway mechanism in the HE-MOF nanorod is directly responsible for the exceptional electrocatalytic performance, which includes an ultralow OER overpotential of 220 mV and remarkable stability sustained for 250 h at a high current density of 100 mA cm–2. It also demonstrates superior performance for urea (UOR, 1.32 V at 10 mA cm–2), ethanol (EOR, 1.31 V at 10 mA cm–2), and methanol (MOR, 1.355 V at 10 mA cm–2) oxidation reactions, significantly outperforming its lower-entropy counterparts. This work demonstrates how Zn ions, supported by graphene oxide, play a crucial role in directing anisotropic growth in high-entropy systems, while simultaneously activating dual-mechanistic pathways to synergistically enhance multianodic reactions.

In-situ growth strategies construct stable triple-phase boundaries. • Molecular-level insight into the enhancement of wettability and dynamics. • Hydrophilic/hydrophobic interfaces selectively promote OER and ORR kinetics. • CoFe-MOF@NCNTs exhibits excellent bifunctional activity (∆E = 0.639 V) and stability. • CoFe-MOF@NCNTs-based RZAB operates stably for over 1320 h. The development of cost-effective non-precious metal catalysts (NPMCs) with high bifunctional activity and stability is vital for advancing rechargeable zinc-air batteries (RZABs). However, simultaneous optimizing of oxygen reduction (ORR) and oxygen evolution (OER) reactions at unified active sites remains challenging. Here, we construct a biomimetic hierarchical porous catalyst featuring stable hydrophilic/hydrophobic triple-phase boundaries through the in-situ growth of nitrogen-doped carbon nanotubes (NCNTs) on hydrophobic CoFe-MOF nanoflowers (CoFe-MOF@NCNTs). The NCNTs network introduces abundant carbon defects and polar nitrogen species that subsequently enrich surface -OH groups, thereby modulating interfacial H 2 O adsorption and establishing a favorable wettability gradient. As a result, CoFe-MOF@NCNTs exhibits outstanding bifunctional oxygen electrocatalysis in alkaline media with a small potential gap of 0.639 V, outperforming commercial Pt/C+RuO 2 (0.695 V). When integrated into RZABs, the devices deliver a high discharge capacity of 796.5 mAh/g Zn , a peak power density of 194.5 mW/cm 2 , and exceptional long-term cycling stability over 1320 h. Moreover, flexible RZABs and liquid Al-air batteries (LAABs) assembled with CoFe-MOF@NCNTs demonstrate excellent mechanical adaptability and promising energy output. This work elucidates the mechanistic role of wettability-engineered interfaces and offers a versatile strategy for designing high-performance bifunctional catalysts toward next-generation portable and wearable energy-storage systems.

Bio-enhanced zeolite nanoplatform (NQZ@ZSM-5) engineered for dentin interfaces. • Synergistic antibacterial, anti-degradation, and remineralization at biointerfaces. • Aged bond strength increases ~2.03× versus a commercial adhesive. • Excellent biocompatibility with preserved interfacial adhesion performance. Dentin adhesives are essential for minimally invasive restorative dentistry. However, the long-term stability of the resin−dentin interface remains limited due to collagen degradation and bacterial erosion. Achieving synergistic antibacterial activity, collagen cross-linking, and remineralization at this interface is therefore crucial for durable dentin bonding. Quercetin (QC), a natural polyphenol, possesses both antibacterial activity and collagen cross-linking capability. These properties can be further enhanced through coordination with metal ions to form metal–phenolic networks (MPNs). In this study, we used the NGV peptide, derived from bone sialoprotein (BSP, a non-collagenous protein), as a remineralization motif. We combined NGV with an MPN to construct a bio-enhanced nanoplatform (NGV/QC−Zn@ZSM-5) for dentin adhesives. The nanoplatform was prepared by incorporating Zn 2+ into ZSM 5 zeolites, followed by surface coating with a QC−Zn MPN and subsequent functionalization with NGV. ZSM-5 serves as a multifunctional carrier due to its high ion-exchange capacity, tunable surface chemistry, and ability to enable controlled Zn 2+ release. The resulting system is designed to stabilize collagen, inhibit bacterial biofilm formation, and promote dentin remineralization. This integrated strategy strengthens the resin−dentin interface against both enzymatic and bacterial degradation, thereby improving bonding durability. Notably, after aging, the modified adhesive exhibited a bond strength approximately 2.03-fold higher than that of the commercial control. Overall, these results highlight the strong potential of this nanoplatform to enhance the longevity and clinical performance of dental bonding restorations.

TiO 2 is a widely studied photocatalyst, but its practical performance is limited by poor light utilization and rapid recombination of photogenerated charge carriers. Herein, a TiO 2 -ZIF-8 heterojunction with a chemically bonded interface was constructed through the formation of Ti-O-Zn interfacial bonds. This design integrates the strong adsorption capacity of ZIF-8 with improved charge separation and transfer across the heterojunction. The optimized TiO 2 -ZIF-8 composite showed markedly enhanced photocatalytic activity, achieving 94.6% degradation of methylene blue within 120 min under simulated solar irradiation. Its apparent rate constant reached k = 0.01508 min -1 , which is 1.55 and 2.38 times higher than those of pristine TiO 2 and ZIF-8, respectively. XPS, FTIR, TEM, and PL results confirm the successful construction of the heterojunction and reveal the key role of Ti-O-Zn bonding in strengthening interfacial interaction and facilitating photogenerated carrier migration. Meanwhile, the strong interfacial interaction improved the structural stability of the composite and helped inhibit nanoparticle agglomeration during photocatalysis. Overall, this work provides new insight into the design of high-performance MOF-based photocatalytic systems through interfacial chemical bond engineering.

By altering the solvent environment to guide the growth of precursors on the (001) crystal plane and the selective adsorption of surfactants, we achieved precise morphological control of Zn-MOF, thereby synthesizing a series of Zn-MOF X with excellent catalytic performance. • The addition of Zn-MOF D effectively addressed the shortcomings of high decomposition temperature and low heat release of AP, significantly reducing its high-temperature decomposition peak by 99.2 °C and significantly increasing the heat release by 469.3%. • 3.The synergistic effect of the high specific surface area and highly active metal centers of Zn-MOF D enhances the thermal decomposition of AP. Modulating the thermal decomposition behavior of ammonium perchlorate (AP) is an effective strategy for optimizing the combustion efficiency of composite solid propellants (CSPs). In this paper, a series of energetic metal-organic frameworks (Zn-MOF X ) with different morphologies were synthesized by solvothermal method and room temperature method, and all of them could effectively catalyze the thermal decomposition of AP. Notably, with the addition of only 2wt% Zn-MOF D , the high-temperature decomposition peak (T HTD ) of AP decreased from 471.4 °C to 372.2 °C, and the heat release increased from 888.3 J·g -1 to 5057.5 J·g -1 . All of this is attributed to its unique structure and high-energy ligands. These results demonstrate that the highly energetic Zn-MOF D material shows great promise as an efficient additive for enhancing the combustion performance of AP-based propellants.

Constructing a stable solid electrolyte interphase (SEI) for isolating the anode from electrolyte is extensively employed to inhibit side reactions and achieve uniform Zn deposition. However, since the SEI inherently allows Zn 2+ transfer, it also inevitably permits H + migration across the interface, thereby triggering hydrogen evolution reactions (HER) and corrosion. Therefore, this work in-situ constructs a hierarchical multifunctional SbZn and ZnF 2 interface layer (SZZF) on the Zn anode surface to address these challenges. Specifically, the outer ZnF 2 -rich layer with hydrophobic properties acts as a physical barrier, facilitating Zn 2+ desolvation and homogenizing Zn 2+ flux. The inner SbZn alloy-rich layer provides abundant nucleation sites and weakens Zn–H + bonding through d-p hybridization, effectively suppressing HER activity and enabling uniform Zn 2+ deposition. Furthermore, the SZZF interface effectively suppresses corrosion-related side reactions induced by the iodine shuttle. Consequently, the SZZF@Zn symmetric cells exhibit exceptional cycling durability of 7000 h. Even under 85% depth of discharge (DOD) at 10 mA cm −2 and 30 mAh cm −2 , the symmetric cell achieves a long cycling life for over 550 h. Remarkably, the SZZF@Zn||I 2 full cell maintains a capacity of 97% after 50,000 cycles, and the SZZF@Zn||I 2 pouch battery with 1.65 Ah stably cycles over 115 cycles. The results present a feasible and efficient interface optimization strategy for realizing highly reversible aqueous zinc iodine batteries.

Ideal electrolytes for low-temperature-resistant aqueous zinc-ion batteries should promote rapid ion desolvation while stabilizing interfacial reactions. Existing research generally introduces additive molecules for optimizing local coordination environment to inhibit H 2 O crystallization; the strong hydrogen bond (HB) effect between co-solvents still exists, and uncoordinated polar groups act as acceptors/donors to induce uneven group coordination and the formation of new strong HB networks. Herein, we propose an electrolyte design strategy with a coordination-induced mechanism to address the long-standing challenges of slow low-temperature kinetics and irregular dendrites in aqueous zinc-ion batteries. By introducing low-carbon polyols to optimize the global solvation structure, low-temperature ice crystallization through intramolecular strain is mitigated, promoting the interaction between non-coordinating solvents to shift from strong HB (O-H:O*, 30 kJ/mol) to weak HB (C-H:O*, 5 kJ/mol), which enables dynamic salt-water-organic cosolvent ternary interaction, promoting rapid Zn 2+ reaction kinetics and stabilizing interfacial reactions. Both experimental and theoretical analyses confirm the effectiveness of the present strategy, which enables low-carbon-polyol-based electrolyte to exhibit a high capacity of 65.13 mAh/g at −25 °C (1 A/g) and a capacity retention of ~95% after 600 cycles.

Background The exploitation of rapid and efficient electrochemical sensors for small inorganic molecules detection is crucial for environment assessment and health surveillance. Pristine metal-organic frameworks (MOFs) display low intrinsic conductivity, and common noble-metal materials suffer from particle agglomeration and high nitrite oxidation potential. Developing high-performance heterostructures for trace nitrite sensing thus remains challenging. Methods In this study, we integrated Au nanoclusters (Au-NCs) into zinc-based metal–organic framework nanopieces (Zn-BDC NPs) to form a novel zinc-based metal–organic framework nanopieces/Au nanoclusters (Zn-BDC NPs/Au-NCs) heterojunction nanocatalyst, which was then applied to the electrochemical detection of nitrite. Au-NCs can compensate for the insufficient conductivity of Zn-BDC NPs, thereby accelerating electron transfer. Combined Density Functional Theory (DFT) calculations reveal that the heterojunction achieves favorable nitrite adsorption energy, which enriches exposed active sites and significantly lowers nitrite oxidation potential. Significant Findings The Zn-BDC NPs/Au-NCs sensor achieves a sensitivity of 116.8 μA/(mM·cm²), a detection limit of 70 nM, and a linear range of 0.7–833.5 μM for nitrite detection. This provides new candidate materials for the precise and efficient detection of nitrite in environmental waters.
