Background As common toxic heavy metals, the combined pollution of Pb(II) and Zn(II) is difficult to remove simultaneously due to the competition between ions, so it is necessary to develop an efficient synergistic treatment strategy. Method The study involved synthesizing functional biochar by co-pyrolyzing DGs with RM, followed by a comprehensive evaluation of its Pb(II)/Zn(II) adsorption capabilities in aqueous environments. Significant findings Multidimensional characterization results confirmed that DGs and RM were well combined, where red mud-derived functional material, such as oxygen-containing functional groups and metallic oxides, successfully loaded onto the distillers' grains-based biochar. Further, the surface properties were also remarkably modified, such as the pore structure and specific surface area were improved, the alkalinity was increased, and magnetic properties were introduced. These modified properties were identified as crucial factors governing Pb(II)/Zn(II) adsorption efficiency. The red mud-modified biochar (RM-DC) exhibited significantly enhanced adsorption capacities for Pb(II) (294.335 mg g -1 ) and Zn(II) (41.456 mg g -1 ) at ambient temperature, representing notable improvements over the pristine biochar (185.038 and 25.038 mg g -1 , respectively). The conformity to both pseudo-second-order kinetics and the Langmuir-Freundlich isotherm model suggests that the adsorption process is characterized by chemical adsorption and multimolecular layer formation. The adsorption of both Pb(II) and Zn(II) on RM-DC was determined to be endothermic and spontaneous. Pb(II) immobilization proceeded through combined surface precipitation, complexation, ion exchange, and electrostatic attraction, while Zn(II) removal was predominantly achieved via ion exchange and electrostatic interactions. RM-DC exhibited promising adsorption capability in treating authentic acid mine drainage, highlighting its potential for practical wastewater purification. This study explores a new way to reuse the industrial bulk solid wastes and provides a highly efficient strategy for heavy metal elimination.

The rational design of bifunctional electrocatalysts with abundant active sites and efficient charge/mass transport is crucial for Zn-air batteries. Here, we report a scalable electrospinning strategy to fabricate Co/N-doped carbon nanofibers (CNFs) with a beaded architecture derived from ZIF-67@PAN precursors. By precisely tuning the ZIF-67 loading, the intercluster spacing along the fibers can be controlled, yielding well-dispersed Co nanoparticles and Co-N x moieties after pyrolysis. Critically, vertically stacked nanofibrous membranes enable scalable manufacturing. The optimized Co/Co-N x -C@CNF-1.5 exhibits superior bifunctional activity (Δ E = 0.815 V), benefiting from balanced active-site density, rapid electron transport, and hierarchical porosity. Density functional theory calculations further reveal the microscopic origin that an appropriate spacing enables moderate electronic coupling between adjacent Co-based active sites, thereby optimizing the adsorption energetics of oxygen intermediates and facilitating ORR/OER kinetics. As an air cathode, the liquid Zn-air battery delivers a peak power density of 406.5 mW cm −2 , an energy density of 976 Wh kg −1 , and a long cycling stability of ∼2143 h. The quasi-solid-state device also shows high power output, stable operation, and excellent flexibility. This work demonstrates a general electrospinning-pyrolysis approach to engineer MOF-derived self-supporting electrodes, bridging high-performance electrocatalysis with practical energy storage applications.

Zinc anode corrosion and dendrite growth in aqueous zinc-ion batteries remain critical challenges that significantly hinder practical application and long-term cyclability. Herein, we present an interface engineering strategy mediated by trace amounts of copper salts, enabling the in situ formation of a uniform and dense Cu-Zn alloy layer on the zinc foil surface for effective anode interface optimization. The CuZn5@Zn composite anode not only lowers the nucleation barrier for Zn2+ deposition and promotes uniform zinc plating to effectively suppress dendrite proliferation but also suppresses parasitic reactions at the electrode/electrolyte interface, thereby contributing to enhanced electrode structural integrity. Electrochemical measurements reveal that the CuZn5@Zn symmetric cell exhibits a stable cycling performance for over 400 h at 1 mA·cm−2 and 1 mAh·cm−2. The CuZn5@Zn||Cu half-cell maintains high reversibility over 500 cycles under 5 mA·cm−2 and 1 mAh·cm−2, achieving a Coulombic efficiency of 98.7%. Moreover, the CuZn5@Zn//VO2 full cell retains 80.2% of its initial capacity after 200 cycles, significantly outperforming the bare Zn anode, which retains only 39%. This study offers insights into the regulation of zinc anode interface performance via trace metal salt engineering.

A superhydrophobic conductive fabric is fabricated via scalable spray-coating of Zn-Co LDH/MWCNTs/POTS. • The fabric achieves > 96% oil-water separation efficiency with excellent cyclic stability. • Integrated electrocatalytic function degrades organic pollutants within 2 h under low voltage. • Robust durability under abrasion, chemical, thermal, and vibration stresses is demonstrated. • COMSOL simulations reveal the wettability–pore synergy governing enhanced separation. The ingress of moisture into aircraft engine lubrication systems poses a serious threat to flight safety and component service life; consequently, there is an urgent need to develop novel multifunctional materials capable of oil-water separation and environmental remediation. In this study, a three-dimensional superhydrophobic conductive fabric with a structure resembling peacock feathers was fabricated for oil-water separation in the aerospace sector. The material was prepared by spraying a composite of zinc-cobalt layered double hydroxide (LDH), modified with perfluorooctyl triethoxysilane (POTS) and multi-walled carbon nanotubes (MWCNTs), onto a conductive fabric substrate. It exhibits superhydrophobicity (water contact angle as high as 161.2°), electrocatalytic degradation capability and oil-water separation capability. The conductive network of multi-walled carbon nanotubes enables electrocatalytic degradation at a low voltage of 20 V, whilst the superhydrophobic surface selectively allows rapid oil penetration, achieving oil-water separation efficiencies of 96–99.4% under thermal radiation conditions. The material maintains stable superhydrophobicity even after repeated cycles and exposure to mechanical abrasion, corrosive media and high-temperature ageing (220°C). COMSOL simulations elucidated the synergistic mechanism between selective wetting and thermal viscosity modulation. This study provides an integrated solution for next-generation aviation fuel systems that combines physical separation with electrocatalytic purification. Furthermore, the coating preparation process is simple and the raw materials readily available, offering significant potential for large-scale mass production.

A portable, high-throughput visual sensing platform was constructed for the effective detection of catechol (CA), on the basis of the single-electrode electrochemistry system (SEES) and a self-enhanced electrochemiluminescence (SEECL) material, namely Au-Ru@Zn metal-organic framework (MOF). It was found that Ru(bpy) 3 2+ and oxalate co‑encapsulated within the Ru@Zn MOF generated a SEECL signal. To further amplify the SEECL response, tripropylamine (TPA) was introduced as an exogenous co-reactant, synergizing with endogenous oxalate to establish dual ECL pathways. The oxidation product of CA, semiquinone radicals, is proposed to effectively quenched photoexcited Ru(bpy) 3 2+ * species and competitively consume the precursor Ru(bpy) 3 3+ by reducing it to Ru(bpy) 3 2+ , thereby causing the ECL signals of Au-Ru@Zn MOF to be significantly quenched. Under optimal experimental conditions, the Au-Ru@Zn MOF-modified SEES exhibited excellent ECL response performance toward CA, with a linear detection range from 1.0 × 10⁻ 9 to 5.0 × 10⁻ 4 mol·L⁻ 1 and a detection limit as low as 7.94 × 10⁻ 10 mol·L⁻ 1 (S/ N = 3). Additionally, the proposed SEES successfully detected CA in tea with the recoveries ranging from 98.8% to 101.0%. This work offers a novel approach for the sensitive detection of CA and has significant application possibilities in the realm of food safety monitoring with the benefits of high throughput, portability, and low cost.

A series of Mg-Al LDH-based photocatalysts were synthesized via a one-pot steam-assisted method, including pure Mg-Al LDH (MA), Zn-In ion-exchange-modified Mg-Al LDH (MAZ), BiOCl-loaded pristine Mg-Al LDH (MAB), and Zn-In-modified Mg-Al LDH co-loaded with TiO2and BiOCl (MA/Zn-In/TiO2/BiOCl, MAZB). The one-pot synthesis facilitated the in situ intercalation and uniform loading of BiOCl/TiO2/Zn-In, while Zn2+/In3+modified the MA layers via ion exchange, leading to an expansion of the interlayer spacing. The innovation of this work is reflected in two aspects: first, all raw materials are added via a one-pot strategy to achieve in situ preparation of modified hydrotalcite; second, this synthetic route features simple post-treatment without complicated washing, pressure filtration, and other tedious operations. The samples were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and N2adsorption–desorption isotherms. The bismuth chloride oxide/TiO2/LDHs exhibited a layered structure, with the active components uniformly distributed between the layers and on the MA surface. Under simulated sunlight irradiation, MAZB achieved 97.5% degradation of 20 mg/L MB within 120 min, with an apparent rate constant of 0.0297 min−1, which is 7.2 times, 2.4 times, and 2.9 times that of MA, MAZ, and MAB, respectively. The degradation rate of MAZB still remained at 89.5% after five cycles, demonstrating excellent stability and reusability. Compared with traditional hydrothermal methods, this steam-assisted system features mild reaction conditions (180 °C, atmospheric pressure), sodium-free raw materials, no washing requirement, and zero waste discharge, showing prominent green advantages.

A chiral metal-organic framework, [Zn( NCG )bpy] n (NCG = N-(4-aminobenzoyl)- L-glutamic acid; bpy = 4,4′-bipyridine), was meticulously designed and synthesized for the first time and thoroughly assessed for its extensive chiral recognition abilities. This MOF features an average pore size of 7.12 nm and is constructed from enantiopure N-(4-aminobenzoyl)-L-glutamic acid ligands, which provide functional sites for the highly enantioselective adsorption and separation of various chiral compounds. The chiral recognition ability of [Zn( NCG )bpy] n was initially tested with batch adsorption of ( R )- and ( S )-dropropizine enantiomers at various starting concentrations and solution pH levels. A dispersive solid-phase extraction (dSPE) strategy coupled with high-performance liquid chromatography (HPLC) was then employed to assess its competitive chiral resolution efficacy toward four structurally distinct racemates: ( R , S )-dropropizine, ( R , S )-tetramisole hydrochloride, (D,L)-phenylalanine, and (D,L)-aspartic acid. The [Zn( NCG )bpy] n exhibited remarkable enantioseparation capability toward smaller amino acid molecules, with an enantiomeric excess ( ee ) of 46.17 ± 1.39% and a separation factor of 2.72 ± 0.10 for (D,L)-phenylalanine in a single batch separation. X-ray photoelectron spectroscopy (XPS), combined with the Independent Gradient Model based on Hirshfeld partition (IGMH) isosurface analysis and binding energy computations, elucidated the underlying recognition mechanism at the atomic level. The results conclusively showed that chiral resolution is primarily regulated by non-covalent host-guest interactions.

Traditional manganese oxide cathodes for aqueous zinc-ion batteries usually suffer from sluggish kinetics and irreversible structure degradation, resulting in poor electrochemical activity and stability. The proposal of Zn 4 SO 4 ·(OH) 6 · x H 2 O-assisted deposition-dissolution reaction model promotes the progress of non‑manganese oxide cathodes in certain systems, but the newly proposed model is of limited applications. Based on the model, exploiting high-quality cathodes and feasible performance regulation strategies are essential for the advancement of zinc batteries. Herein, a feasible method is proposed to realize in-situ substitution of Co, In, Zn, and V heteroatoms in Fe 3 O 4 with N-doped carbon coated via the assistance of a Fe-based metal organic framework precursor. The in-situ adulterated metal heteroatoms are proved to have distinct effects on electron structure regulation, triggering more active electron transfer, thus enhancing the efficient interactions with charge carriers. Moreover, the polydopamine derived N-doped carbon shell and unique hollow bipyramidal hexagonal prism structure provide abundant active sites and guarantee sufficient space for electrolyte transport. The hollow structures could homogenize flux distribution and electric field distribution, facilitating high-efficiency and stable energy storage. Consequently, the electrochemical activity, kinetics, and stability could be remarkably optimized. In addition, electrochemical performance improvement mechanisms triggered by in-situ multiple heteroatoms substitution and structure design are revealed by systematic characterizations, computations, and simulations. This study proposes a feasible electron structure regulation strategy triggered by in-situ multiple heteroatoms substitution for non-MnO 2 cathode design, which is of great importance for the development of zinc batteries.

Fe-, Ni- and Zn- doped La 0·9 Sr 0·1 CoO 3 are prepared and a single-component solid oxide fuel cell composed of 30 wt% perovskite oxide and 70 wt% samarium-doped ceria (SDC)-(Li 0·67 Na 0.33 ) 2 CO 3 is fabricated and characterized. When doping with either Fe, Ni or Zn, most cations occupy the Co 3+ sites. X-ray photoelectron spectroscopy and oxygen temperature-programmed desorption characterizations show that Zn-doped La 0·9 Sr 0·1 CoO 3 exhibits notably high surface oxygen, causing higher catalytic activity for oxygen reduction reaction (ORR) than that of nondoped La 0·9 Sr 0·1 CoO 3 . Fe or Ni doping into La 0·9 Sr 0·1 CoO 3 decreases surface oxygen, resulting in a lower catalytic activity toward ORR than La 0·9 Sr 0·1 CoO 3 . Furthermore, X-ray diffraction, temperature-programmed reduction and transmission electron microscopy characterizations prove that after reduction, Fe-doped La 0·9 Sr 0·1 CoO 3 is reduced to Co 0·72 Fe 0.28 alloy-oxide core-shell nanoparticles , resulting in a high catalytic activity for hydrogen oxygen reaction (HOR). However, NiCo 2 O 4 are formed during the reduction of Ni-doped La 0·9 Sr 0·1 CoO 3 , exhibiting a low catalytic activity for the HOR. Similarly, the low catalytic activity of reduced Zn-doped La 0·9 Sr 0·1 CoO 3 for the HOR is caused by the formation of ZnCo 2 O 4 . A single component fuel cell composed with Fe-doped La 0·9 Sr 0·1 CoO 3 -SDC-(Li 0·67 Na 0.33 ) 2 CO 3 exhibits the highest P max of 239.1 mW cm −2 at 700 °C with H 2 as fuel, indicating that HOR processes are rate-determining steps.

All-solid-state lithium batteries (ASSLBs) empolying sulfide solid electrolyte and lithium metal anode can afford improved energy density and safety. However, their large-scale application is hampered by the rigidity of ceramic–based electrolyte and the inevitable growth of lithium dendrites . Herein, a novel, flexible, high-conductivity and free-standing sulfide electrolyte membrane (Li 6 PS 5 Cl-polypropylene carbonate6, (LPSCl-PPC6)) with a thickness of 60 μm is prepared via methodology of blade coating and hot pressing, which exhibits a high Li + conductivity (3.1 × 10 −3 S cm −1 at 25 °C) and a wide electrochemical window (4.7 V vs Li + /Li) at 25 °C. Additionally, a bifunctional interphase with Li-Zn/LiCl is implanted on lithium metal surface to enhance the stability of electrolyte/lithium anode, which effectively prevents the growth of lithium dendrites and the internal short circuit of lithium symmetric battery. Benefiting from the synergistic effect, the assembled ASSLBs of S-CNTs/LPSCl-PPC6/Li-Zn/LiCl|Li and LLZO@NCM93/LPSCl-PPC6/Li-Zn/LiCl|Li exhibit high initial capacity of 1183.5 mAh g −1 (193.6 mAh g −1 ) and exceptionally cyclic stability with capacity retention of 89.2% over 150 cycles at 0.05C (93.2% over 100 cycles at 0.1C). This highly conductive sulfide-based composite electrolyte and interface engineering provides a promising strategy for achieving high performance ASSLBs.

Bimetal cluster catalysts present boosted catalytic performance in numerous reactions due to their coordinatively unsaturated metal sites and synergy. Nevertheless, constructing ultrafine and stable bimetal cluster catalysts that can be well applied under harsh high-temperature reaction conditions is still a tough challenge. Herein, we propose a spatial and chemical dual-confinement strategy to design hierarchical ZSM-5 zeolite-confined PtZn bimetal catalysts with ultrafine clusters (ca. 1.2 nm) and high stability against sintering, which can be controllably synthesized via a microwave-assisted one-pot hydrothermal approach. The optimized PtZn@ZSM-5 cluster catalyst exhibits remarkably boosted propane dehydrogenation (PDH) performance, with a propane conversion of ca. 60% and a propylene selectivity of >96% (WHSV = 3 h–1, 600 °C). Both experimental and theoretical studies demonstrate that Pt species are well anchored by the hierarchical pores and framework zinc, constructing highly dispersed active Pt–(O–Zn)x species responsible for the boosted catalytic performance. This work affords a facile and general dual-confinement strategy to synthesize ultrafine bimetal cluster catalysts for PDH, which can be well extended to other catalyst systems, such as RhZn@ZSM-5 and IrZn@ZSM-5.

A Zn dosage-mediated thermal reconstruction strategy was proposed to fabricate LDH@ZIF derived catalyst. • Moderate Zn addition achieves uniformly dispersed ZnCo 2 O 4 spinel. • Optimized LZ-0.2 removes levofloxacin rapidly through multiple ROS pathways involving 1 O 2 . • The catalyst realizes stable 144 h continuous degradation in fixed-bed reactor. Peroxymonosulfate-based advanced oxidation processes (PMS-AOPs) are effective for refractory antibiotic removal, yet conventional layered double hydroxide (LDH) catalysts often suffer from lamellar collapse, active site aggregation and poor pore accessibility after calcination. Herein, a series of LDH(Co/Al)@ZIF-8 derived catalysts (LZ-x) were prepared through the growth of ZIF-8 on LDH(Co/Al), followed by pyrolysis, for PMS activation and levofloxacin (LFX) degradation. Regulating the Zn dosage controlled ZIF-8 growth and the subsequent thermal reconstruction of the hybrid precursor. Among them, LZ-0.2 exhibited an open hierarchical architecture and the highest catalytic activity, achieving 95.11% LFX removal within 5 min with a k obs of 0.576 min −1 . In addition, structural characterization indicated that an appropriate Zn dosage favored the formation and dispersion of ZnCo 2 O 4 -containing spinel domains within the porous nanosheet architecture. Meanwhile, mechanistic investigations supported a hybrid radical/non-radical oxidation pathway involving 1 O 2 , •OH, SO 4 •- and • O 2 − . Additionally, the LZ-0.2 + PMS system maintained effective performance in various real water matrices and stable fixed-bed operation for 144 h in hospital wastewater, with low Co and Zn leaching. Moreover, phytotoxicity, antibacterial activity, and zebrafish developmental toxicity were reduced after treatment. This work highlights Zn-dosage regulation as an effective strategy for directing the thermal reconstruction of LDH@MOF derived catalysts for efficient PMS activation and antibiotic abatement.
