p-Nitrophenol (PNP), a widely used chemical intermediate, exhibits stubborn resistance to conventional oxidation treatments due to its high toxicity, electron-deficient nature, and the high stability of its aromatic ring. To address the bottlenecks of low mineralization efficiency of PNP by traditional ozonation and the limited spectral utilization of conventional PCO systems. Herein, we constructed a photocatalytic–ozone synergistic system based on perylene diimide-based organic polymers (Urea-PDI/O 3 /vis). Owing to the broad spectral response of the polymers, the light-responsive range of this coupled system can be extended to the near-infrared region up to 700 nm. The degradation rate of PNP in this system is 25 times higher than that in the photocatalytic system alone and 2.42 times greater than that in the ozone system alone. More importantly, the mineralization efficiency of PNP is significantly enhanced in the Urea-PDI/O 3 /vis, reaching a value three times higher than that of the traditional ozone system. Mechanism investigation reveals that the denitrification efficiency for PNP is comparable between the ozonation and photocatalytic–ozone systems. However, the photocatalytic–ozone process demonstrates a marked superiority in the subsequent ring cleavage and mineralization via decarboxylation of small-molecular organic acids. In contrast to the direct ozonation mechanism dominated by electrophilic and dipolar addition reactions, the Urea-PDI/O 3 /vis efficiently utilizes photogenerated electrons to convert ozone into hydroxyl radicals in large quantities, which enables highly efficient mineralization of PNP. This study will provide new insights into the removal of PNP in water.

Given the limited performance of traditional biochar adsorbents, this study proposes an innovative two-step pyrolysis strategy for the precise synthesis of N F double-site co-doped biochars (NFBCs). This strategy effectively regulates the pore structure and surface chemistry of the material. The optimized material (NFBCs-1:3) exhibited an ultra-high specific surface area (2187 m 2 /g) and abundant active sites. Its maximum adsorption capacity for norfloxacin (NOR) reached 552.65 mg/g, significantly exceeding that of traditional biochar and most reported materials. The adsorption process followed pseudo-second-order kinetics and the Sips model. Mechanistic studies showed that its excellent performance stems from the synergistic effects of pore filling, π-π interactions, hydrogen bonding, and electrostatic interactions, with the unique N F double-site regulation of the electronic structure as the key. In addition, NFBCs-1:3 maintained excellent adsorption performance across a wide pH range, under coexisting ion interference, and in a variety of real-world water matrices, confirming its great application potential in the treatment of complex real-world wastewater. This study provides a new idea for the design of efficient and stable non-metal-doped carbon-based adsorbents.

The urea oxidation reaction (UOR), as a key process in renewable energy technologies and wastewater treatment, suffers from sluggish reaction kinetics due to its six-electron transfer characteristics, necessitating the development of highly efficient catalysts. In this work, a one-pot method combined with a sodium borohydride (NaBH₄) etching strategy was employed to successfully prepare porous Mo doped NiFe layered double hydroxide (P-Mo-NiFe-LDH), achieving a significant enhancement in UOR performance. Studies revealed that Mo doping altered the microscopic morphology of NiFe-LDH and promoted the transition of Ni 2+ /Fe 2+ to higher valence states (Ni³⁺/Fe³⁺), thereby improving the reaction kinetics. Meanwhile, the porous structure constructed by NaBH₄ etching not only exposed abundant active sites but also optimized the electron transport pathways. This synergistic effect of morphology regulation and electronic structure optimization enabled P-Mo-NiFe-LDH to exhibit outstanding catalytic performance in a 1 M KOH + 0.33 M urea electrolyte: a current density of 10 mA•cm⁻² was achieved at just 1.39 V (vs. RHE), with a Tafel slope of 38.7 mV•dec⁻¹, demonstrating a clear advantage over most reported NiFe based catalysts. This catalytic potential is 90 mV lower than that of the water oxidation reaction, offering certain energy-saving benefits. The synergistic strategy of surface pore structures and heteroatom doping in this work provides new insights for designing high-performance LDH-based electrocatalysts.

This study presents a novel electrochemical strategy for detecting organophosphorus pesticides based on the synergistic catalytic of red kidney bean esterase (RKBE) and iron–cobalt dual-atom catalyst embedded in N-doped carbon carrier (FeCo–NC). RKBE was extracted from the widely cultivated British red kidney beans ( Phaseolus vulgaris L.) . FeCo–NC exhibited excellent electrocatalytic and peroxidase-like activity, catalyzing o -phenylenediamine oxidation to produce electroactive 2,3-diaminophenazine, which served as signal probe generating a sensitive cathodic current. Notably, RKBE product 1-naphthol inhibited FeCo–NC activity, while organophosphorus pesticides counteracted this inhibition by suppressing RKBE activity, restoring the electrochemical signal of 2,3-diaminophenazine. Leveraging this signal-regulation mechanism, a dichlorvos sensor was developed, with wide linear range (50–50,000 pM), low detection limit (14 pM), and excellent real-sample recovery (93.33%–107.08%), demonstrating practical application potential. This study provides an affordable and easy-to-operate approach for large-scale on-site monitoring of organophosphorus pesticide residues in foods.

As an important and free amino acid, taurine (Tau) shows extensive application in pharmaceuticals. The coexistence of inorganic salts during the production process affects the purity and quality of Tau. Present study firstly described a novel method to separate Tau and Na2SO4 by forming deep eutectic solvents (DESs) in situ. Ethanolamine (MEA) was chosen as the optimal hydrogen bond donor to pair with Tau. After removal of Na2SO4, taurine was stripped out from in situ DES using n-propanol as reverse solvent with the yield of 98% and trace impurities (Na2SO4 and NaCl contents less than 13.70 mg•g -1 and 12.93 mg•g -1 , respectively). On the optimized parameters, the Tau purification and separation process were further elucidated using quantum chemical calculations and molecular dynamics simulations together. Results showed the interaction energy of 116.1 kJ/mol between MEA and Tau, confirming the superiority of Tau purification using DES in situ.

Skin-like soft electronics exploiting gels containing biomass-derived components raise increasing research attention, in which multifunctional lignin has been extensively explored. Nevertheless, elevating the lignin loading usually sacrifices the performance, limiting their application potentials. Herein, we develop a unique polymerizable deep eutectic solvent (PDES) consisting of a quaternary ammonium monomer and lactic acid to incorporate with high-density lignosulfonate (LS) of > 20 wt.% and address the performance trade-offs. The lignin-induced self-catalytic polymerization associated with electrostatic assembly enables room temperature gelation within < 5 min and ambient-air micropatterning. Remarkably, the anionic LS and polycationic matrix affording multiple non-covalent interactions drastically enhance the mechanical strength to > 1 MPa and versatile adhesion up to > 500 kPa, meanwhile allowing self-healing, photothermal, and antibacterial capabilities. Such LS-PDES eutectogels also permit ion conduction (> 3 mS cm −1 ) and superior environmental adaptivity over −80°C to 100°C. Thus, employing the in situ polymerization between electrodes, rapid prototyping of bend-/impact-resistant flexible supercapacitors is demonstrated to power wearable sensors. More importantly, it facilitates the production of miniaturized soft organic electrochemical transistor (OECT) arrays, whose performance can be well maintained under deformed and extreme temperature conditions. This high-lignin-density eutectogel platform paves a straightforward route towards printed soft ionotronics, bioelectronic interfaces, and brain-inspired computing.

Aqueous rechargeable zinc metal batteries (ARZMBs) have attracted increasing attention as sustainable energy storage systems capable of mitigating the intermittency of renewable energy, due to their high safety, low cost, and environmental friendliness. However, their practical applications are still hindered by several critical issues, including poor low-temperature performance, slow ion diffusion of the electrolytes, and severe gas generation reaction at the interface between the electrolyte and the electrode. In recent years, the design concept of high-entropy electrolytes (HEEs) has been introduced into aqueous energy storage systems. By introducing diverse ions or solvent molecules, it is possible to enhance the entropies of the system, including configurational, tetrahedral, and mixing entropy, thereby enabling control over the solvation structure, hydrogen bond network, and interfacial reactions. However, the concept of entropy remains relatively abstract and challenging for newcomers to grasp. Moreover, the performance enhancements achievable through different types of entropy vary considerably, and a systematic review comparing these effects is currently lacking. This work reviews the fundamental principles of HEEs, strategies for entropy modulation, and recent advances in their applications for ARZMBs. Special emphasis is placed on the mechanisms by which configurational entropy optimizes the Zn 2+ solvation structure, as well as the role of tetrahedral entropy in modulating the hydrogen bond network. Finally, we discuss the challenges and future directions for HEEs in the development of high-performance, wide-temperature-range, and long-lifespan ARZMBs, with the aim of providing theoretical guidance to advance green energy storage technologies.

Current development in cellulose-based sensors remain restricted by limited mechanical strength and insufficient sensitivity range. Inspired by coral structure, we report a Janus cellulose aerogel (JCA) based triboelectric sensor (JCAS) featuring a unique double cellulose crosslinked network. The biomimetic structure enhances intermolecular interactions and optimizes the molecular chain structure, significantly improving mechanical stability and operational durability. Consequently, the JCA demonstrates a remarkable 437.5% increase in Young's modulus compared to pristine cellulose aerogel (PCA), enabling it to withstand loads over 50 000 times its own weight. The corresponding JCAS exhibits high performance, including stable operation under high-pressure (300 kPa for 4 h), an extended cycling longevity, and a reliable sensing range of 0–800 kPa which is the widest reported to date for cellulose-based triboelectric sensors to our knowledge. Biocompatibility tests further confirm their suitability for wearable applications. Finally, we demonstrate the practical utility of JCASs by integrating them into wearable devices for human posture recognition. This work provides a novel strategy for synthesizing crosslinked cellulose aerogels, promoting the practical applications of cellulose-based triboelectric sensors.

Nickel-iron layered double hydroxide (NiFe-LDH), as a highly promising non-precious metal catalyst for the oxygen evolution reaction (OER), still suffers from several inherent drawbacks, including poor electrical conductivity, insufficient exposure of active sites, and a decline in performance under high current densities. These limitations severely restrict its practical application in the oxygen evolution reaction. Herein, a nanosheet morphology Pr-doped NiFe layered double hydroxide catalysts (Pr-NiFe-LDH) was synthesized in situ on the surface of Nickel foam modified by dielectric barrier discharge (DBD) plasma (PNF). The addition of Pr elements can effectively adjust the electronic structure of NiFe-LDH, change the position of the d-band center, and increase the number of active sites, thereby enhancing the catalytic activity. The overpotential of Pr-NiFe-LDH was reduced to 321 mV at 100 mA•cm -², significantly lower than that of NiFe-LDH (342 mV) and even superior to that of commercial RuO₂ catalyst (441 mV). The density functional theory (DFT) study indicates that adding Pr to the surface of NiFe-LDH enhances its performance in the OER. This work not only deepened the understanding of the OER mechanism in the NiFe-LDH catalyst, but also provided valuable insights for the design of efficient, low-cost and noble-metal-free electrocatalysts.

Aqueous zinc-ion batteries (AZIBs) have emerged as promising energy storage systems owing to their high safety, low cost, and environmental friendliness. However, their practical application faces critical challenges, including the formation of Zn dendrites and the occurrence of parasitic side reactions. These phenomena not only hinder ion transport kinetics but also cause rapid capacity decay and potential battery failure. To address these limitations, we developed a sustainable double-crosslinked cellulose hydrogel electrolyte by integrating micron-sized cellulose and cellulose nanofibers (CNFs). The hydrogel electrolyte, constructed from cellulose components with distinct size scales, exhibits a well-organized hierarchical porous network structure, which significantly facilitates the migration of zinc ions. Specifically, nanocellulose serves as a reinforcing filler that enhances the mechanical strength of the dual-network electrolyte, thereby inhibiting Zn dendrite growth. Additionally, abundant carboxyl polar functional groups were also introduced as high-affinity Zn 2+ binding sites to mitigate side reactions. Consequently, the assembled Zn//Zn symmetric cells with this electrolyte demonstrate superior cycling stability exceeding 1 100 h at current density of 0.5 mA/cm 2 , along with a high-capacity retention of 79.9% after 1 000 cycles in the Zn//V 2 O 5 battery. Furthermore, this cellulose hydrogel electrolyte is easily accessible and biodegradable, paving the way for the scalable production of high-performance and environmentally friendly energy storage devices.

The urea oxidation reaction (UOR) has garnered significant attention as a promising alternative to the oxygen evolution reaction (OER) for water electrolysis, owing to its superior kinetic properties that enable enhanced hydrogen production efficiency. However, the practical deployment of UOR technology remains hindered by the persistent challenge of developing electrocatalysts that simultaneously achieve high activity, long-term operational stability, and cost-effectiveness. Herein, we report a facile, eco-friendly, one-step synthesis process to fabricate nickel–tin electrocatalyst (Ni–Sn) on Ni foam for catalyzing UOR via electrodeposition, using SnCl 2 ·2H 2 O and NiSO 4 ·6H 2 O as the Sn and Ni sources, respectively. Notably, the Ni–Sn electrocatalyst with a Ni/Sn ratio (90.39:8.61 at%) exhibits remarkable UOR activity, delivering a low potential of 1.493 V versus RHE to reach 10 mA·cm −2 , a small Tafel slope of 83.5 mV·dec −1 , and excellent stability with minimal decay after 100 h of continuous operation in alkaline urea electrolyte (1.0 M KOH + 0.33 M urea). The excellent activity of the Ni–Sn electrocatalyst for UOR benefits from the synergistic interaction between Ni and Sn, which modulates the electronic structure and accelerates charge transfer kinetics, thereby significantly enhancing reaction dynamics. Furthermore, the intrinsic superhydrophilicity of the Ni–Sn catalyst promotes efficient mass transport of reactants and products, contributing to its superior bifunctional catalytic performance for UOR.

Nitrogen-doped micro-mesoporous carbon nanospheres are considered as promising CO₂ adsorbents due to their remarkable efficiency and cost-effectiveness. In this work, nitrogen-doped micro-mesoporous carbon nanospheres were constructed, during which soft micelles (triblock copolymer P123) and a hard template (silica sol) as structural precursors were employed, and urea was used as the nitrogen source and KHCO₃ as the chemical activator. Through a combined chemical activation and post-doping strategy, ultra-micropores were successfully introduced into the carbon framework alongside rich nitrogen doping. The final nitrogen-doped micro-mesoporous carbon nanospheres exhibit high specific surface areas (529–2225 m²/g) and nitrogen contents ranging from 2.20 wt% to 6.02 wt%. The optimal sample, NMCNs-2K2U800, demonstrates excellent CO₂ adsorption performance, with capacities of 7.86 mmol/g at 0 ℃ and 4.31 mmol/g at 25 ℃ under 1 bar. This study systematically investigates the effects of activator and nitrogen source on the pore structure, nitrogen speciation, and CO₂ adsorption behavior of carbon materials. Further, a viable strategy for the controlled synthesis of porous carbons and providing valuable insights into the design of high-performance CO₂ adsorbents is provided.
