Non-graphitizable carbon (NGC) has been obtained by carbonizing tubular polypyrrole (T-PPy) synthesized through a self-degraded template method . K-NGC/S composite has been prepared by mixing S with K-NGC via melt-diffusion method where NGC has been activated by potassium hydroxide (denoted as K-NGC) and is used as a conductive additive. The as-prepared K-NGC/S composite shows good specific discharge capacity and rate capability with an initial specific discharge capacity of 1121.9 mAh g − 1 and a specific discharge capacity of 729.7 mAh g − 1 after 50 cycles at a current density of 335 mA g − 1 , which is better than pure S. This improvement in the specific discharge capacity and the rate capability of the cell with K-NGC/S composite as a cathode material is realized by the existence of K-NGC, which can offers a superb conductive environment for S, effectively encapsulate S, restrain the outward diffusion of polysulfides , buffer volume change upon cycling and reduce the dissolution of lithium polysulfides into the electrolyte. The good electrochemical performance of K-NGC/S composite would make it become a promising cathode material for lithium-sulfur batteries.

Zinc-ion batteries (ZIBs) are promising candidates for safe and environmentally benign energy storage systems because they possess a high theoretical capacity (820 mAh g −1 ), abundant natural reserves, a low electrochemical potential (−0.76 V vs. SHE), and superior safety characteristics. However, the practical application of zinc (Zn) anodes is hindered by undesirable reactions, including Zn dendrite growth, hydrogen evolution, and Zn anode corrosion. In this study, we designed a novel Zn anode protective layer through carboxylation modification of aramid nanofibers (ANFs). This engineered protective layer aims to regulate Zn deposition behavior and enhance battery cycling stability. Specifically, the carboxylated ANF (cANF) layer enhances hydrophilicity, improving electrolyte wettability at the anode-electrolyte interface. Furthermore, it effectively modulates the Zn 2+ deposition orientation, suppressing dendritic growth. Consequently, the cANF@Zn symmetric cell demonstrated stable cycling for 750 h at 3 mA cm −2 and 1 mAh cm −2 , significantly outperforming the performance of the cells with bare Zn anode. Moreover, the cANF@Zn | V 2 O 5 full cell exhibited substantially enhanced cycling stability compared to the cells using bare Zn anodes. These results demonstrate that the introduction of cANF layer is an effective strategy for mitigating critical challenges of Zn anodes.

With high theoretical energy density and low cost, lithium‑sulfur batteries are viewed as next-generation energy storage technologies. But issues like the polysulfide shuttle effect and electrolyte safety concerns hinder their commercialization. Here, we present a novel cathode-supported black phosphorene modified composite polymer solid electrolyte membrane (CS-BP-CPSEM) made from polyethylene oxide-polyvinylidene fluoride polyblend and black phosphorene. Black phosphorene nanosheets, produced via electrochemically assisted liquid-phase exfoliation, are uniformly dispersed in the composite polymer matrix and directly multilayer tape-cast onto the cathode surface. This design improves interfacial contact and Li + transport. The optimized CS-BP-CPSEM with 0.3 wt% BP shows a 5.37 V electrochemical stability window and 1.3 × 10 −3 S cm −1 ionic conductivity at 60 °C. Polysulfide adsorption tests confirm black phosphorene's strong anchoring ability, effectively lessening the shuttle effect. Consequently, the assembled all solid-state lithium sulfur battery (ASSLSB) delivers a high discharge capacity of 1322 mAh g −1 and maintains 453 mAh g −1 after over 100 cycles at 0.05C. This work offers a promising interfacial engineering strategy using two-dimensional materials to boost high-energy-density and long-cycle-life solid-state Li-S battery development.

Commercial AC is employed as the support to fabricate the P-CoO/Co 9 S 8 @AC electrode. • The formation of P-CoO/Co 9 S 8 @AC realizes the deep coupling of macroscopic structural buffering and atomic-scale electronic regulation. • The synergy of heterointerface and P doping enhances OH − adsorption and accelerates redox reaction rate. • The ASC achieves a high energy density of 90.4 Wh kg −1 at 750 W kg −1 . Supercapacitor performance is largely determined by electrode materials. Transition metal compounds (TMCs) have high theoretical capacities but suffer from sluggish charge transport and volume-induced structural degradation, which limits their practical applications in energy storage. To overcome the inherent bottlenecks of TMCs in energy storage, this work reports a novel dual-regulation strategy to construct a P-doped CoO/Co 9 S 8 heterostructure anchored on activated carbon (P-CoO/Co 9 S 8 @AC). The formation of the P-doped CoO/Co 9 S 8 @AC heterostructure enables close coupling between macroscopic structural buffering and atomic-scale electronic modulation. Introducing activated carbon (AC) suppresses particle agglomeration and buffers volume expansion, while the synergistic effect of heterointerface engineering and P doping significantly reduces the charge-transfer resistance to 0.27 Ω. Benefiting from these multidimensional advantages, the as-prepared material delivers a specific capacity of 1697.3 C g −1 (3394.6 F g −1 ) at 1 A g −1 , outperforming previously reported nickel sulfide/nickel oxide heterostructures (2278 F g −1 ) and P-doped ternary cobalt-based sulfide electrodes (2716 F g −1 ). Density functional theory (DFT) calculations show that the P-doped heterostructure has an OH − adsorption energy of −4.82 eV and an upshifted d-band center, thereby improving intrinsic conductivity and OH − interfacial adsorption. Furthermore, the assembled hybrid supercapacitor (HSC) achieves a high energy density of 90.4 Wh kg −1 at a power density of 750 W kg −1 , while retaining 86.1% of its capacity after 20,000 cycles. This study provides a design strategy for constructing high-performance composite electrodes by integrating heterointerface engineering and heteroatom doping. A novel strategy is reported to construct P-CoO/Co 9 S 8 @AC. DFT calculations demonstrate that the synergistic effect of CoO/Co 9 S 8 heterostructure formation and P doping strengthens OH − adsorption and boosts the electrochemical performance.

Tailored pore network FPCE was designed as the electrolyte for FCS. • Cement-PA-KOH-AM20 integrates good electrochemical performance with outstanding mechanical flexibility. • Operates reliably at −10-65 °C, resists damage, provides 7 °C insulation, and retains performance after 6 months outdoors. • Powers LEDs, phones, displays, and fans even under bending or twisting. Cement-based supercapacitors are emerging as key enablers of the green transition, unifying the widespread infrastructural presence of cement with the ability to store electrical energy. However, their inherent rigidity has hindered integration into irregular, free-form architectural surfaces. Here, we report the first flexible cement-based supercapacitor, which combines high electrochemical performance with exceptional mechanical adaptability. The device employs a cement-composite electrolyte engineered with a tailored network of mesopores and capillary pores, achieving an ionic conductivity of 35.28 mS cm −1 alongside a low Young's modulus of 81.6 MPa. In an asymmetric electrode configuration, the supercapacitor delivers an areal capacitance of 215.3 mF cm −2 , an energy density of 76.55 μWh cm −2 , and a power density of 726.95 μW cm −2 , with 83.3% capacitance retention over 2000 cycles. It operates reliably from −10 to 65 °C, withstands mechanical damage without failure, provides a 7 °C thermal insulation benefit, and shows negligible performance loss after six months outdoors. Capable of efficient solar energy storage, it can power small electronic devices such as LEDs, a mobile phone, and fans even when bent or twisted. This work demonstrates a versatile, deformable energy-storing cement, paving the way for multi-function building materials in next-generation free-form architecture.

A semi-immobilized CL coating is designed for stable Zn anodes. • Hydrophobic framework isolates water and repels SO 4 2− via sulfonate. • Ca 2+ tip-shielding and lignosulfonate anions guide uniform Zn deposition. • Symmetric cell cycles 4500 h; full cell retains 93.99% after 1500 cycles. Aqueous zinc-ion batteries (AZIBs) are attractive candidates for large-scale energy storage, yet the zinc anode is plagued by parasitic reactions and dendrite growth. Herein, we propose a semi-immobilized ion-regulation concept by engineering a hydrophobic composite coating on zinc foil (denoted as CL@Zn coating) to form the CL@Zn electrode. The coating consists of calcium lignosulfonate (CL), conductive carbon black, and PVDF. Unlike conventional fully solid coatings or fully dissolved additives, this design enables a small fraction of CL to controllably dissolve, releasing functional lignosulfonate anions and Ca 2+ ions, while the majority remains anchored within the three-dimensional (3D) framework. This creates a dynamic, synergistic protection system: the coating physically repels water and SO 4 2− ; the dissolved anions regulate Zn 2+ transport and favor (101)-oriented Zn growth, while released Ca 2+ ions contribute to a “tip-shielding effect” against dendrites. Moreover, a compact yet microporous Zn 4 SO 4 (OH) 6 ·xH 2 O (ZHS)-derived interfacial layer forms in situ at the coating/electrolyte interface, acting as a beneficial SEI-like interphase that facilitates interfacial ion transport and further stabilizes Zn deposition. Consequently, the CL@Zn symmetric cell cycles for nearly 4500 h at 0.5 mA cm −2 , and the CL@Zn//MnO 2 /CNT full cell exhibits a capacity retention of 93.99% after 1500 cycles at 1 A g −1 . This work presents a versatile, biomass-derived dynamic interface strategy for durable metal anodes. A semi-immobilized calcium lignosulfonate coating creates a hydrophobic, ion-regulating interface that suppresses dendrites and side reactions, enabling ultra-stable zinc anodes for aqueous zinc-ion batteries.

Pesticide residues on dried star anise remain major barrier to product safety and quality; current washing practices unfortunately fail to balance decontamination efficiency with retention of bioactive compounds. Suitability of emerging decontamination media, in particular alkaline electrolyzed water (ALEW), for star anise has nevertheless not been assessed. The present study therefore compared use of ALEW with use of conventional methods at ambient and high-temperature conditions to decontaminate star anise; four representative fungicides were tested. Quality of dried star anise was then determined in terms of color, rehydration behavior, shikimic acid and volatile oil contents. ALEW treatment at ambient temperature provided superior pesticide reduction (9.3–14.7%) compared with other treatments; such treatment also led to enhanced rehydration capacity and color. Unexpectedly, high-temperature soaking markedly reduced effectiveness of ALEW and caused significant losses of shikimic acid and volatile oils. Machine learning modeling identified support vector regression as most accurate tool to predict influences of pH, soaking temperature and soaking time of ALEW on pesticide residues decontamination and reveals distinct parameter sensitivities among different pesticides. Short-duration, ambient ALEW treatment offers practical and quality-preserving solution for pesticide control in star anise processing, with clear implications for sustainable spice manufacturing.

Given the confining effect of porous carbon and strong surface polarity of transition metal phosphides, their composite would be a promising cathode candidate to solve the problems of lithium–sulfur batteries including volume expansion and the shuttling effect of polysulfides. Herein, cobalt phosphide (CoP)-loaded phosphorous (P)-containing carbonized bamboo (CoP/PCBs) composites were fabricated via the co-pyrolysis of phytic acid, waste bamboo and Co(NO3)2·6H2O via Joule heating at 600–1200 °C. Hydrogen radicals released from phytic acid enabled CoP/PCBs with developed porosity (438.1–812.4 m2/g). CoP nanoparticles coated with graphitic carbon were distributed uniformly on a porous matrix of PCBs. CoP/PCBs presented obviously enhanced adsorption capabilities for Li2S6, and 57.8–80.4 wt.% of sulfur was confined in CoP/PCBs/S cathodes. CoP/PCB heated at 1200 °C exhibited a high reversible capacity of 477.5 mAh/g after 500 cycles at a current density of 1 C with an average capacity decay rate of 0.045%. The specific capacity remained at 453.3 mAh/g after 300 cycles even under a high sulfur load of 4.0 mg/cm2. Conversion of sulfur/polysulfides during the electrochemical process could be promoted via the physical confinement of sulfur and chemical confinement of Li2S6. This work provided a valuable reference for the facile fabrication of lithium–sulfur cathodes and utilization of metal phosphides in advanced lithium–sulfur battery systems.

The growing global energy crisis and increasing greenhouse gas emissions necessitate the development of sustainable energy technologies. However, existing methods for synthesizing biomass-derived carbon materials suffer from limitations such as poor conductivity during low-temperature carbonization, high energy consumption during high-temperature activation, and the need for corrosive reagents, resulting in suboptimal electrochemical performance of the carbon materials. To address these challenges, this study proposes a novel composite thermoelectric dual-field electrochemical technology that converts lignin into high-capacitance carbon materials under low-temperature conditions (550 ℃). Using alkali lignin and poplar leaves as raw materials, the products obtained through pyrolysis (2 h) and electrolysis (4 h, 2.8 V) exhibited specific surface areas of 286 and 388 m 2 g − 1 , respectively. In a three-electrode system, the specific capacitance at a current density of 0.5 A g − 1 reached 230 and 177 F g − 1 ; at a current density of 0.1 A g − 1 , the specific capacitance reached 343 and 270 F g − 1 . Furthermore, the resulting materials exhibited excellent rate capability and cycling stability; after 5,000 charge-discharge cycles in a 6 M KOH aqueous solution at a current density of 5 A g − 1 , the capacitance retention rates reached 99.6% and 99.5%, respectively. This molten salt-assisted thermoelectric dual-field method provides a new approach for the low-temperature, efficient preparation of porous carbon materials for biomass-based supercapacitors.

Achieving uniform zinc deposition is crucial for high-performance
aqueous zinc-ion batteries, yet it remains a significant challenge.
While functional separators based on metal–organic frameworks
(MOFs) like UiO-66-NH 2 offer a promising route to regulate
ion flux, their effectiveness is often hampered by the energy-intensive
synthesis of MOFs and their poor dispersion within polymer matrices.
Herein, we report a rapid, room-temperature ultrasound-assisted synthesis
that yields UiO-66-NH 2 with a unique surface-fused morphology
and a hierarchical pore system within just 1 h. Unlike its conventional
counterpart with a well-defined octahedral shape, this ultrasound-induced
MOF (U-UN) forms a homogeneous and tightly integrated composite with
cellulose nanofibers, constructing a separator with optimized ion-transport
channels and interfacial stability. The U-UN-based separator demonstrates
superior ionic conductivity and Zn 2+ transference number,
effectively guiding the preferential growth of Zn along the (002)
plane. Consequently, a Zn||Zn symmetric cell equipped with this separator
achieves an ultrastable cycling life exceeding 1180 h, and a Zn||MnO 2 full cell retains nearly 100% capacity after 600 cycles at
1 A g –1 . This work not only presents a green and
efficient synthesis strategy for advanced MOFs but also provides fundamental
insights into the design of functional separators through microstructure
engineering for long-lasting metal batteries.

Antibiotic-resistant bacteria (ARB) and their genes (ARGs) pose a significant risk to public health and the ecosystem. Conventional water disinfection efficiently eliminates pathogens, however, it requires intensive chemical consumption but inefficiently removes ARGs. Herein, we propose an on-demand electrochemical platform that simultaneously eliminate both ARB and ARGs with in-situ generated hydroxyl radicals (·OH) without additional chemical inputs. Single-atom copper catalysts with CuN 4 coordination structure (SA-CuN 4 /NC) are precisely tuned to directly convert oxygen into controllable ·OH via three-electron oxygen reduction reaction (3e⁻ ORR). Operando X-ray adsorption near-edge spectroscopy reveals a potential-driven self-reconstruction of single-atom Cu sites to optimize ·OH concentration. Specially, the preferentially adsorbed H + onto the adjacent N atoms promotes the breaking of Cu-N bonds to form stable Cu 2 -CuN 2 cluster as a genuine active site. As expected, the SA-CuN 4 /NC with moderate ·OH (~11.5 μM) exhibits ultra-fast degradation of E. coli HT115 , accomplishing an ~ 8 log removal within 1 min and a complete elimination of ARGs in 30 min. Excess ·OH (~47.9 μM) triggers bacterial aggregation which compromises bacterial inactivation. These findings demonstrate that 3e⁻ ORR is a sustainable and effective strategy to obtain fast and complete water disinfection, preventing environmental spread of ARGs.

Fluazinam is a benzamide fungicide commonly used in agricultural
production to prevent and control fungal-induced plant diseases. However,
its residues in food products can pose potential health hazards. To
address this issue, we have developed an electrochemical sensor based
on a MOF-5/AB-modified glassy carbon electrode (GCE) for sensitive
detection of fluazinam. In this work, a high-performance electrochemical
sensor was fabricated via a simple composite strategy by combining
AB, which possesses high electrical conductivity and superior electron
transfer ability, with MOF-5, a material featuring a well-developed
porous structure and large specific surface area. The structural and
morphological characteristics of the MOF-5/AB and electrochemical
sensing performance toward fluazinam of MOF-5/AB/GCE are investigated.
The MOF-5/AB/GCE exhibited outstanding electrochemical sensing performance
for fluazinam detection, providing an ultralow detection limit of
0.0166 μM, a wide linear range of 0–100 μM, high
sensitivity, excellent reproducibility and stability, and remarkable
selectivity against common interfering species. In real samples, fluazinam
yielded high recovery rates, confirming the potential of MOF-5/AB/GCE
for practical environmental and biomedical monitoring applications.
This research provides a novel and efficient sensing platform for
electrochemical detection of fluazinam residues and offers a valuable
reference for modification of MOFs and their extended applications
in the field of electrochemical sensing.
