The anodic oxygen evolution reaction (OER) process is essential in new technologies such as water electrolysis and metal-air batteries. However, it often exhibits suboptimal efficiency and delayed kinetics. This study presents a novel and new design for the fabrication of homogeneous FeNiBTC/SSM (SSM = stainless steel material) with tunable crystalline properties by a self-sacrificial and in situ synthesis from a recycled stainless steel substrate. The modified stainless steel template enhances the material’s properties compared to the original mesh substrate and its structure can be attributed to the typical MIL-100 (Material of Institute Lavoisier) structure, which is a hierarchically structured, highly chemically stable material formed by FeO6 octahedral clusters around a single shared oxygen anion. The as-synthesized FeNiBTC/SSM4 catalyst exhibited excellent electrocatalytic performance for OER, as indicated by its small Tafel slope (74.5 mV dec −1 ), low overpotential (η 10 223.7 mV), and high current retention (95.4 %) after a stability test lasting 45 h. The study demonstrates the development of water-based and self-sustaining MOF electrocatalysts for the oxygen evolution reaction in a simple process, along with a novel method for reusing renewable resources.

2D layered materials are regarded as prospective catalyst candidates due to their advantageous atomic exposure ratio. Nevertheless, the predominant population of atoms residing on the basal plane with saturated coordination, exhibit inert behavior, while a mere fraction of atoms located at the periphery display reactivity. Here, a novel approach is reported to attain complete atom activation in 2D layered materials through the construction of an interlayer biatomic pair bridge. The atoms in question have been strategically optimized to achieve a highly favorable state for the adsorption of intermediates. This optimization results from the introduction of new gap states around the Fermi level. Moreover, the presence of the interlayer bridge facilitates the electron transfer across the van der Waals gap, thereby enhancing the reaction kinetics. The hydrogen evolution reaction exhibits an impressive ultrahigh current density of 2000 mA cm −2 at 397 mV, surpassing the pristine MoS 2 by approximately two orders of magnitude (26 mA cm −2 at 397 mV). This study provides new insights for enhancing the efficacy of 2D layered catalysts.

Effective removal of pollutants that affect human health and ecosystem stability is a crucial challenge. Here, the structural confinement engineering strategy realizes the effective anchoring of atomically dispersed Co in the B-doped-CN network (BCN) (BCN/CoN[2 +2]). The advanced oxidation process (AOP) involved BCN/CoN[2 + 2] has realized the rapid and complete degradation to tetracycline (TCL), the removal of approximately 80% and 100% of tetracycline was achieved in 5 min and 30 min, respectively. The AOP with BCN/CoN[2 + 2] can degrade TCL over a wide pH; in addition, BCN/CoN[2 + 2] has the ability to efficiently degrade common pollutants, and its catalytic activity did not decay even if it was used repeated five times. Electron paramagnetic resonance (EPR) spectroscopy shows that BCN/CoN[2 + 2] drives the complete conversion of peroxymonosulfate (PMS) to 1 O 2 , and density functional theory calculations demonstrate that the base for the conversion of PMS to 1 O 2 is from the isolated state of the active site Co.

View large Download slide View large Download slide Close modal Metal-organic framework (MOF) materials, characterized by their porosity and large specific surface areas, exhibit excellent adsorption properties. With the aim of removing Te(IV) from environmental aquatic systems, this study is the first to propose the use of MIL-100(Fe). The material reveals a strong adsorption capacity for Te(IV), with maximum adsorption of 531.9 mg/g, superior to other adsorbent materials. Adsorption isotherm and kinetic models indicate that the adsorption process primarily involves monolayer chemical adsorption. According to the thermodynamic parameters, the adsorption reaction is endothermic. The experiment individually examined factors affecting the material's adsorption performance, including adsorbent dose, initial concentration of Te(IV), pH, adsorption time, and coexisting ions. Even under high ion strength conditions and high concentrations of coexisting ions, the material's adsorption efficiency for Te(IV) still reached over 94%. The material has been successfully applied to remove Te(IV) from lake water, river water, and seawater, yielding satisfactory results. Due to the high salinity and ionic strength of the solution, the removal efficiency of Te(IV) in the seawater matrix was slightly lower than that in freshwater (river and lake water). Thus, this material shows promise for the removal of Te(IV) from complex aquatic systems. MIL-100(Fe) was prepared and characterized. The Te(IV) can be adsorbed by MIL-100(Fe) effectively, and the adsorption process was primarily a monolayer chemical adsorption and an endothermic reaction. The Te(IV) can be removed effectively in environmental water supplies by MIL-100(Fe).

Nano-scaled polypyrrole (PPy) particles have been successfully synthesized with the help of Triton X-100 micelles via soft template approach. The polypyrrole nanoparticles have been spin-coated on surface acoustic wave (SAW) transducers to demonstrate their sensing capability toward acetone gas exposure. Field Emission Scanning Electron Microscopes (FE-SEM) and Fourier transform infrared (FT-IR) spectroscopy have been utilized to characterize these PPy nanoparticles. The PPy nanoparticles have an average diameter of 95 nm. The responses of the sensors are linearly associated with the acetone concentrations in the range from 5.5 ppm to 80 ppm. In response to 5.5 ppm acetone exposure, the response and recovery time are 9 s and 8.3 s, respectively. SAW sensors coated with PPy nanoparticles were potentially useful to detect acetone.

Nitrogen-doped carbons (NC) and carbon nitride (C 3 N 4 ) belong to the two fundamental pillars of functionalized carbon materials that have broad applications in different fields. The synthesis of NC and C 3 N 4 often starts from different precursors, and a general approach that can offer both architectures is still highly sought. Herein, a facile Triton X-100-assisted copolymerization-carbonization strategy is reported to fulfill this task. By moderating the weight ratios of Triton X-100 and several conventional precursors of C 3 N 4 ( e.g ., dicyandiamide, urea, and cyanamide), a series of both types of N-functionalized carbons with controllable N dopants is successfully afforded. The yielded solids transform from graphitic C 3 N 4 with low surface areas to porous NC when the weight ratio reaches the critical values. This phenomenon might be attributed to the intensified copolymerization between the intermediates of both starting precursors during the carbonization, resulting in increased oxygen content and decreased N:C ratio in the products. Both the bulk and activated carbon-supported materials are then designed and used as metal-free catalysts in the dehydrochlorination of ethylene dichloride, a key reaction in polyvinyl chloride manufacture. It is found that NC is significantly more active than C 3 N 4 , but the corresponding supported catalysts exhibit an opposing trend. The structure-activity correlations suggest both the number of different N defects and the surface areas might play key roles in determining the dehydrochlorination chemistry.

Polymyxin B (PMB) was an antibiotic with highly effective antibacterial effect but narrow safety interval, and its residues in food had attracted widespread attention. It was important to develop an accurate method for the rapid detection of PMB in animal foods. In this work, we had established a ratiometric sensing system based on the formation of supramolecular assemblies of pyrenyl probes, which were driven by the synergy of noncovalent forces such as multiple-electrostatic and π-π stacking interactions. Compared with the traditional fluorescence detection based on the single wavelength change, the present approach showing two-wavelength fluorescence response could reduce the interference of other factors making the experimental results more accurate. The sensor exhibited high sensitivity and selectivity with a low detection limit (28.3 nM). This method could be used to realize visual detection and had a visual detection limit of 1 μM. As we had learned yet, this was the first ratiometric sensor for PMB detection in aqueous solution. We believed all our preliminary would not only provide a complementary strategy for the detection of PMB, but also develop some new ideas for the construction of sensors for rapid antibiotic detection.

Basic research on nanoelectronics is often limited by the high cost and large-scale methods to fabricate electrodes with controlled gap size in nanometer scales. Here nanoelectrodes with a controlled gap size of sub-100 nm were fabricated by modified nanoimprint lithography (NIL) via a double-layer lift-off process utilizing polymethylmethacrylate (PMMA) and polydimethylglutarimide (PMGI) as the lift-off resist. Firstly the patterns of the electrode mold were transferred onto the upper PMMA layer by NIL techniques and then through controlling the developing time and concentration of developer of the PMGI under layer, regulating the exact gap size of the transferred metal nanoelectrode. The result indicated that the 'undercut' phenomenon was observed of the PMGI transfer layer during the developing process; through controlling the feature size of the undercut length, the gap size of the transferred metal nanoelectrode was precisely controlled, which showed shrinkage behavior. The nanoelectrodes with gap sizes of 800, 400, 200, and 100 nm can be reduced to about 440, 120, 80, and 70 nm. Our result provides a low-cost and large-scale route to prepare nanoelectrodes with controlled gap size, which can be valuable for current efforts in nanoelectronics.

To improve the performance of MIL-100(Fe) in the photo-peroxydisulfate (photo -PDS) degradation system, this study introduced the amino-containing bidentate ligand 5-aminoisophthalic acid (AIA) to simultaneously engineer structural defects and photosensitive sites, thereby synergistically enhancing both photocatalytic activity and metal-mediated catalytic capability. This study synthesized MIL-100(Fe) materials with varying AIA incorporation levels (denoted as M-x %NH₂) and systematically investigated the effects of AIA integration on the catalyst. Degradation experiments were performed in the photo-PDS system using rhodamine B (RhB) as a model pollutant. The results demonstrate that the introduction of AIA induced multiple advantageous effects in the photo-PDS process:1.It enhanced the visible-light absorption capacity;2.Improved the separation efficiency of photogenerated charge carriers;3.Generated defects to increase metal active sites, thereby accelerating PDS activation. Among the samples, M-30 % NH₂ exhibited the optimal performance, achieving nearly complete degradation of RhB within 50 min. The pseudo-first-order rate constant (k) was three times higher than that of unmodified MIL-100(Fe). The catalyst retained approximately 90 % degradation efficiency after five consecutive cycles and demonstrated robust performance across pH 3–9, along with the capability to degrade diverse organic pollutants. Quenching experiments confirmed sulfate radicals (·SO 4 ⁻) and hydroxyl radicals (·OH) as the main active species, and the degradation pathways were elucidated. This study provides foundational insights for modifying MIL-100(Fe) and developing high-efficiency PDS catalysts.

Enzyme-like activity and efficiency of nanomaterials are strongly controlled by their size, composition, and structure, and hence the structural parameters need to be optimized. Here, we report that two-dimensional Pd nanoplates enclosed by {100}-facets [{100}PdSP@rGO] exhibit substantially enhanced intrinsic oxidase-like activities relative to the {111}-facets ones and Pd nanocubes in catalyzing the chromogenic reaction of 3,3′,5,5′-tetramethylbenzidine. By taking ascorbic acid 2-phosphate as the substrate, which transforms to ascorbic acid in the presence of acid phosphatase (ACP), the {100}PdSP@rGO could be used as an efficient nanozyme for colorimetric ACP detection without resorting to destructive H2O2. A good linear relationship from 0.01 to 6.0 mU/mL with a detection limit of 8.3 μU/mL is obtained, which is better than most previously reported ACP assays. Importantly, the excellent assay performance could be successfully applied to ACP determination in serum samples with high accuracy. This study demonstrates that the enzyme-like activity of nanomaterials could be finely tuned simultaneously by controlling their exposed crystal facets and high specific surface area.

Aqueous zinc-ion batteries (AZIBs) represent a promising technology for grid-scale energy storage due to their intrinsic safety, environmental sustainability, and low cost. However, their practical implementation is hindered by severe anode instability issues, including uncontrollable dendrite growth and water-induced parasitic reactions. Here, we introduce sodium hexadecyl diphenyl ether disulfonate (SHDD) as a cost-effective, multifunctional electrolyte additive. The amphiphilic structure of SHDD– anion enables comprehensive interfacial regulation: the sulfonate groups facilitate Zn2+ desolvation while reducing water activity, and the adsorbed anions form a hydrophobic barrier that effectively suppresses the hydrogen evolution reaction (HER) and byproduct formation. Additionally, SHDD– anion adsorption induces vertically aligned and highly compact Zn2+ deposition along the Zn(100) crystal plane. Benefiting from this synergistic mechanism, the assembled Zn||Zn symmetric cells achieve exceptional cycling stability over 4200 h, while Zn||Cu half-cells maintain a 99.66% Coulombic efficiency. Furthermore, full cells with an NH4V4O10 cathode deliver 233.40 mAh g–1 at 1 A g–1 and retain 83% capacity after 600 cycles. Therefore, this study highlights the potential of molecular design in modulating crystal orientation and interface engineering for high-performance next-generation AZIBs.

Smart wearable sensing systems necessitate self-powered, high-sensitivity pressure sensors that can operate efficiently across a wide temperature range. Here, we present a high-energy-density aqueous magnesium metal battery (AMMB) textile for ultrasensitive pressure sensing from −40° to 100°C. The AMMB-type pressure (AMMB-P) sensing textile features a porous quasi-solid-state polyethylene oxide–magnesium chloride electrolyte that inhibits magnesium corrosion via hydrogen-bond anchoring, paired with a breathable carbon cloth cathode and woven magnesium anode. The innovative design achieves an ultrahigh sensitivity of 687.32 millivolts per kilopascal, a low detection limit (0.96 pascals), long-term durability (200,000 cycles), and exceptional breathability (water vapor permeability, 2281.4 ± 249.8 grams per square meter per day; air permeability, 628.0 ± 9.1 millimeters per second). The unique anticrystallization properties of electrolyte ensure a stable operation of the AMMB-P sensing textile in extreme temperatures ranging from −40° to 100°C. Under high-pressure condition, our AMMB-P sensing textile can be converted into a reliable power source with high energy density of 287.92 watt-hours per kilogram, ensuring stable self-powered operation. Coupled with machine learning, the AMMB-P sensing array enables intelligent object recognition and autonomous robotic control even under harsh conditions. Our work advances self-powered pressure-sensing textiles tailored for extreme-environment exploration, enabling interactive perception in humanoid robots and individual health management under harsh service conditions.
