Heteroatom doping and carbon coating are essential techniques for improving the conductivity and reaction kinetics of intercalation-type anode materials in lithium-ion batteries. However, it is difficult to achieve heteroatom doping and carbon coating at the same time through simple processes. Here, we propose a simple method to simultaneously achieve carbon-coating and P/S/N triple-doping by introducing polyphosphazene (PZS) as precursor. We first prepare PZS-coated titanium-based metal-organic frameworks (MIL-125), which can be readily converted into phosphorus/sulfur/nitrogen (P/S/N) co-doped carbon-coated titanium dioxide (TiO 2 ) nanocomposites (PSN-C@TiO 2 @C) by simple calcination under an inert atmosphere. The heteroatom doping and carbon hybridization synergistically enhance the conductivity and ion diffusion of the PSN-C@TiO 2 @C, which not only change the local charge density of the nanocomposite, but also generate more active sites. Benefiting from the above advantages, the well-designed PSN-C@TiO 2 @C anode exhibits significantly improved specific capacity and rate performance, maintaining high reversible specific capacities of 272.2 mA h g −1 after 1000 cycles at 1000 mA g −1 and 141.1 mA h g −1 after 2000 cycles at 5000 mA g −1 . This study presents a novel simplified method for multi-element-doping and carbon-coating, which can be generally applied for developing advanced electrode materials for energy storage application.

The contamination of water by soluble hexavalent uranium (U(VI)) requires the development of highly active and stable treatment materials. This study presents a rational design for a heterostructured photocatalyst by coupling phosphorus-modified graphitic carbon nitride (PCN) with NiAl-layered double hydroxide (NiAl-LDH). The structural theory was that P-doping would tailor the optoelectronic properties of g-C₃N₄, while integration with NiAl-LDH would establish a synergistic system for concurrent adsorption and photoreduction. As anticipated, the P modification inhibited crystal growth and improved charge separation in g-C₃N₄, elevating its U(VI) reduction rate by 3.67-fold. The NiAl-LDH component provided a high-specific-surface-area substrate for pollutant enrichment. The resulting optimal NiAl-LDH/PCN composite formed a Type-II heterojunction, which directed efficient charge transfer between the two phases. Under simulated sunlight, the composite achieved high removal efficiencies of 96.0% for U(VI) and 95.2% for Cr(VI). The performance stems from a synergy where NiAl-LDH concentrates target ions at the interface, and PCN furnishes photogenerated electrons via facilitated charge transfer, thereby accelerating the photoreduction kinetics. The material also demonstrated robust reusability and effectiveness in treating actual wastewater, highlighting its strong potential for practical heavy-metal-ion remediation.

The transition from petroleum-derived chemicals to sustainable alternatives has intensified interest in 2,5-furandicarboxylic acid (FDCA), a biomass-derived monomer for green polyester production. However, many non-noble metal catalysts for converting 5-hydroxymethylfurfural (HMF) to FDCA still require multistep syntheses and/or harsh oxidation conditions. Here, we report a straightforward molten-salt strategy to prepare nitrogen-doped porous carbon–supported cobalt catalysts (Co@N-C-x). Under ambient air at 90 °C in water, the optimized [email protected] catalyst affords complete HMF conversion and > 99 % FDCA yield, with a productivity of ~1.17 mol FDCA mol Co −1 h −1 , and retains 96.5 % yield in an initial 400-fold scale-up test. Mechanistic and kinetic analyses support a sequential pathway of HMF → HMFCA → FFCA → FDCA, with the FFCA-to-FDCA step being kinetically most demanding under the present conditions. Structure–activity analysis, together with atmosphere-dependent experiments, indicates that Co–Nₓ sites serve as the primary catalytic centers, while adjacent defect-rich surface sites (denoted as O₂-activation sites) promote dioxygen activation and facilitate stepwise oxidation. Density functional theory calculations further show that FDCA binds more strongly to the catalyst surface than the intermediates, which can hinder product desorption and contribute to the observed loss of activity upon recycling.

Ceramic-gel composite electrolytes (CGEs) attract significant attention as solid-state electrolytes (SSEs) for sodium metal batteries owing to their favorable ionic conductivity and interfacial compatibility. However, conventional CGEs generally feature insufficient mechanical strength and consequent uncontrollable dendrite growth, remaining long-standing fundamental challenges that severely limit practical applications. Herein, this study presents a high-strength CGE that enables efficient stress transfer, achieving a compressive strength of 20.1 MPa (20 times higher than conventional gel electrolytes), while maintaining excellent ionic conductivity and effectively suppressing sodium dendrites. The 3D-Na 3 Zr 2 Si 2 PO 12 framework further serves as a thermal barrier, imparting the CGE with superior flame retardancy. Additionally, Na/CGE/NVP-K 0.05 cells exhibit 75.9% capacity retention after 10,000 cycles at 5C (25 °C) and deliver 78.5 mAh g −1 at 30C (60 °C). Remarkably, the CGE exhibits excellent low-temperature adaptability, retaining nearly 100% capacity at –20 °C. These results highlight a viable strategy for designing safe and high-performance solid-state sodium metal batteries toward practical deployment.

Nonradical oxidation via peroxymonosulfate (PMS) activation has attracted considerable attention for organic pollutant degradation, while the control and regulation of singlet oxygen ( 1 O 2 ) generation in catalytic oxidation are still challenging and the underlying mechanism remains ambiguous. In this paper, we synthesized a nitrogen-doped carbon-supported manganese-based catalyst by using ZIF-8 as a metal-organic framework (MOF) template for the in-situ loading of active components. When used for peroxymonosulfate activation, the MnO-Mn 6 N 2.58 /N-C catalyst exhibits a high Bisphenol A (BPA) degradation rate of 0.133 min -1 , exceeding PMS oxidation alone by 67 times. Mechanistic investigations reveal that the degradation process relies on the direct electron transfer from heterogeneous catalysts to PMS, contributing to efficient 1 O 2 generation for BPA degradation via a nonradical pathway. We demonstrate that Mn(II)/Mn(III) redox cycling on the catalyst surface activates PMS into superoxide (O 2 • - ), which in turn converts into 1 O 2 , thereby elucidating the underlying mechanism for high-efficiency degradation. This work provides a novel strategy to design heterogeneous Mn-based catalysts for recalcitrant organic wastewater remediation via a nonradical oxidation pathway.

Core–shell Bi 4 NbO 8 Cl@C plate-like heterostrutured photocatalysts were successfully prepared by one-step hydrothermal process, during which glucose solution exhibited reducibility and created amounts of oxygen vacancies for Bi 4 NbO 8 Cl, while a carbon layer was in situ deposited on Bi 4 NbO 8 Cl by glucose decomposition. The structure of Bi 4 NbO 8 Cl was stabilized and armored by the thickness-tailored C layer, which provides a superior performance in the removal of acidic Cr(VI)-contained contaminant water, and the optimal Bi 4 NbO 8 Cl@C achieved 373 folds than pristine Bi 4 NbO 8 Cl in photocatalytic Cr(VI) removal. Experimental results and density functional theory (DFT) calculations show that C layer is tightly coated on the surface of BNC. Furthermore, C–O covalent bonds, which act as electron transfer channels, are formed at the interface of BNC and C layer. This study provides an important reference for the synthesis of core–shell structured photocatalysts and the efficient removal of Cr(VI) from industry wastewater. Graphical

The development of high-performance electromagnetic wave (EMW) absorption materials that are effective in harsh environments remains a significant challenge. Herein, a lightweight, flexible, and robust three-dimensional hybrid aerogel is fabricated for efficient broadband EMW absorption. The aerogel is constructed by integrating metal-organic framework (MOF)-derived magnetic CoNi@C nanoparticles and carboxylated multi-walled carbon nanotubes (c-MWCNTs) into an aramid nanofiber (ANF) framework. The synergistic effect between the components endows the composite with remarkable attenuation capability via conductive loss, dielectric loss, magnetic loss, and interfacial polarization. The optimized aerogel exhibits exceptional EMW absorption performance, achieving a minimum reflection loss (RL min ) of −59.66 dB at a thickness of 2.68 mm and a broad effective absorption bandwidth (EAB) of 7.96 GHz at a thickness of 2.94 mm. This work provides a promising strategy for designing advanced EMW absorption materials with integrated properties of strong absorption, wide bandwidth, and environmental resistance for use in aerospace, military, and electronic protection fields.

The development of cost-effective, highly active and durable Pt-based electrocatalysts for oxygen reduction reaction (ORR) remains a major challenge to advancing proton exchange membrane fuel cells (PEMFCs). Hollow nanoarchitecture loaded with metal alloys has been widely used as a nanoreactor to regulate electronic structure of active sites and enhance reactant enrichment. In this study, PtCo alloy nanoparticles are uniformly dispersed on both outer and inner surfaces of hollow TiN spheres and carbon composite support (Pt 3 Co/H-TiN-C). The optimized Pt 3 Co/H-TiN-C nanoreactor delivers a mass activity of 64 mA mg Pt −1 and a specific activity of 0.122 mA cm Pt −2 at 0.90 V vs. RHE in 0.1 M HClO 4 solution. Furthermore, the Pt 3 Co/H-TiN-C nanoreactor enables an effective four-electron transfer pathway with high selectivity and low H 2 O 2 yield (less than 3%) toward ORR process. After accelerated durability tests, the half-wave potential of Pt 3 Co/H-TiN-C shows a decay of only 24 mV after 10,000 cycles, markedly smaller than Pt/C catalyst (74 mV). The enhanced durability and ORR kinetics of Pt 3 Co/H-TiN-C are attributed to the synergistic effect of strain effect in PtCo alloy, strong interactions between PtCo and H-TiN-C, and nanoreactor architecture. These features not only regulate the Pt electronic structure, increasing the Pt 0 content, but also expose more accessible active sites on the outer/inner surfaces to accelerate charge/mass transport. Moreover, alloyed Co atom suppress the dissolution of Pt, endowing an improved durability. This work provides a new strategy for designing efficient and durable Pt-based ORR catalysts for PEMFCs.

The commercialization of lithium-sulfur (Li–S) batteries is primarily hindered by the polysulfide shuttle effect and sluggish reaction kinetics. Engineering a host material that synergizes efficient polysulfide confinement with high electrical conductivity, through a simple and potentially scalable process, remains a key challenge. Here, we demonstrate a facile, one-pot hydrothermal strategy to cost-effectively convert abundant natural halloysite clay into a mesoporous silicon-carbon composite (MHSC). This process effectively establishes an intimate Si – C bonded interface between the conductive carbon network and the polar silica framework, inherited from the mineral precursor. The resulting MHSC host exhibits excellent electronic conductivity (0.011 S cm −1 ) and strong polysulfide adsorption. When evaluated as a sulfur cathode, the MHSC/S composite delivers a high initial capacity of 1213 mAh·g −1 at 0.2 C and, more importantly, exceptional long-term stability with a negligible capacity decay rate of only 0.089% per cycle over 700 cycles at 1 C. This work provides a commercially viable and environmentally benign route for manufacturing high-performance Li–S battery cathodes by upcycling natural clay resources.

Graphite positive electrode-based anion-intercalation aqueous dual-ion batteries using bis(trifluoromethanesulfonyl)imide anion intercalations show the potential because of the high discharge plateau (>1.4 V vs. the standard hydrogen electrode at 25 °C ± 2 °C) for anion chemistry. However, currently, the electrochemical performance of aqueous dual-ion batteries based on bis(trifluoromethanesulfonyl)imide anion intercalation can only be achieved in highly concentrated salt electrolytes. This dependence on high anion concentration to activate intercalation inevitably leads to high costs and prevents operation at low temperatures (e.g., < −20 °C). In this context, we explore a hydrogel electrolyte rich in dipole molecules, incorporating only 1 M lithium bis(trifluoromethanesulfonyl)imine and 2 M zinc chloride, with expanded electrochemical stability windows (>4.6 V at −40 °C) to activate bis(trifluoromethanesulfonyl)imide anion insertion into the graphite positive electrode through high-voltage scanning to 3.0 V. The assembled aqueous dual-ion batteries based on bis(trifluoromethanesulfonyl)imide anion intercalation demonstrate high discharge plateaus of 1.9 V at −20 °C and 1.7 V at −40 °C, along with a specific energy of 595 Wh kg −1 (normalized to the 1 mg cm −2 of the graphite positive electrode).

Photocatalytic conversion of polyols and nitrogen-containing small molecules into value-added chemicals via C–N coupling reaction represents a promising route for dual waste treatment of waste plastics and wastewater. However, precisely controlling the coupling pathway of key intermediates to achieve high product selectivity remains a significant challenge. Here, we report a WO3 photocatalyst that enables the highly selective synthesis of glycine from waste poly(ethylene terephthalate) (PET)-derived ethylene glycol (EG) and nitrate, achieving a remarkable glycine yield of 1.87 mmol gcat–1 h–1 with 89% selectivity, which significantly outperforms conventional TiO2-based systems. Mechanistic studies indicate that the high selectivity stems from the distinct reaction pathway on WO3, where glycolaldehyde is stabilized as the key intermediate to efficient C–N coupling with NH4+ derived from NO3– reduction. This contrasts with the TiO2-catalyzed pathway that proceeds via the more oxidized glyoxal, which readily undergoes overoxidation to the byproduct formic acid. By using different plastic/biomass-derived feedstocks (methanol, ethylene glycol, and glycerol), this process can be expanded to the scale synthesis of various C–N compounds. Preliminary techno-economic analysis and life-cycle assessments suggest the potential economic viability and environmental benefits of this process. This work establishes a sustainable photocatalytic strategy for the valorization of waste plastic and wastewater by regulating key intermediates to enable a selective C–N coupling pathway.

Personal protective textiles showing high-performance electromagnetic wave absorption (EWA) along with multiple functions demonstrate considerable application prospects in daily life. Herein, a single-step, environmentally friendly, water-based fabrication strategy is developed to produce a durable and highly efficient EWA coating on PET fabrics, simultaneously integrating antibacterial, antistatic, and high-performance water/sweat-wicking properties. This multifunctional coating is realized through the synergistic interaction of its coating constituents including the incorporation of Co@C nanoparticles (NPs) derived from Co-based zeolitic imidazolate frameworks (ZIF-67), the in situ reduction of graphene oxide (GO) facilitated by fatty acid methyl ester ethoxylate sodium sulfonate (FMES), and the 3-glycidyloxypropyl triethoxysilane (GPTMS)-mediated cross-linking. The resulting Co@C/rGO/GPTMS-coated PET fabric exhibits excellent moisture-wicking and water adsorption capacity. Benefiting from the combined effects of conduction loss, interfacial polarization loss, and a hierarchical surface structure, it demonstrates outstanding EWA performance with an RLmin of −56.5 dB and EABmax covering the entire X-band. The incorporation of Co@C and rGO within the coating matrix imparts robust antibacterial and antistatic properties, achieving an antibacterial rate of over 99% against both Staphylococcus aureus and Escherichia coli, along with a significant reduction in static voltage to 130 V and a short half-life of merely 0.01 s.
