Zn-doped V 2 O 5 /NH 4 V 4 O 10 heterojunction in-situ constructed on carbon cloth. • Electronic mismatch drives interfacial charge rearrangement and coupling. • Heterointerface boosts Zn 2+ kinetics and suppresses V dissolution to prevent degradation. • Heterostructure cathode delivers high capacity and ultra-stable cycle life. Layered vanadium-based heterojunctions and cation pre-intercalation serve as effective strategies to address sluggish ion diffusion and inferior structural stability of aqueous zinc-ion batteries. Herein, hierarchical Zn-doped V 2 O 5 /NH 4 V 4 O 10 heterojunction is in-situ grown on carbon cloth via two-step hydrothermal treatment. The fabricated heterojunction accelerates Zn 2+ migration and eliminates discharge kinetic limitations of pristine cathode materials. It also restrains Jahn-Teller distortion to mitigate lattice degradation and improve structural reversibility. Benefiting from structural and interfacial advantages, the obtained cathode delivers a high specific capacity of 523.8 mA h g −1 , outstanding rate performance and 72.4% capacity retention over 3000 cycles at 3 A g −1 . It maintains 171.4 mA h g −1 at 5 A g −1 and exhibits 96.37% capacity recovery after current adjustment. This work offers a promising interfacial engineering route for advanced aqueous zinc-ion battery cathodes and expands the application prospect of vanadium-based layered heterostructures.

The electrocatalytic nitrate reduction to ammonia (eNO 3 RR) offers a sustainable route to simultaneously decarbonize ammonia production and remediate nitrate wastewater. However, its efficiency is challenged by a complex multi-step reaction pathway; to address this, we designed a tandem copper‑cobalt catalyst supported on a carbon/nitrogen/oxygen substrate (CuCo-CNO). The carbon substrate not only provides stable anchoring sites for active metals but also facilitates strong electronic coupling between the tandem Cu and Co sites, thereby significantly enhancing catalytic activity and selectively promoting the critical eNO 3 RR steps. The CuCo-CNO catalyst achieves a high Faradaic efficiency of 96.5% and an ammonia selectivity of 95% at −0.8 V vs. RHE, significantly outperforming its single-metal counterparts (Cu-CNO and Co-CNO). In situ electrochemical-Raman spectroscopy reveals that the initially metallic Cu Co sites undergo electrochemically driven reconstruction into Cu 2 O and CoOOH. Compared with the single-metal analogs, theoretical calculations further indicate that CuCo-CNO exhibits a higher energy barrier for H 2 evolution and a lower eNO 3 RR energy barrier, confirming the synergistic catalytic mechanism. A Zn-NO 3 − battery assembled with CuCo-CNO as the cathode delivers a maximum power density of approximately 3.35 mW cm −2 . This work offers a valuable strategy for designing tandem catalysts on carbon supports for efficient electrocatalytic nitrate-to-ammonia conversion.

Recurrent infections and persistent inflammation pose significant challenges in the clinical treatment of infected bone defects. Here, a porous scaffold of Zn-0.8Li-0.5Ag with a TPMS-Gyroid structure was fabricated by laser powder bed fusion (LPBF) for the treatment of infected bone defects, integrating mechanical performance, anti-infective properties, and osteogenic requirements. In vitro, Zn-0.8Li-0.5Ag scaffold exhibits potent bactericidal property against Staphylococcus aureus ( S. aureus ) and Escherichia coli ( E. coli ), excellent anti-inflammatory property through immunomodulation, and acceptable osteogenesis property by enhancing the expression of osteogenesis-related genes. In vivo, the Zn-0.8Li-0.5Ag scaffold significantly suppresses pathogenic bacteria, alleviates local inflammation, and promotes tissue regeneration. RNA sequencing further elucidated that the Zn-0.8Li-0.5Ag scaffold exerted anti-inflammatory effects by releasing Zn 2 + , Li + , and Ag + , which downregulated Gbp2 expression, thereby inhibiting inflammatory pathways. Collectively, the Zn-0.8Li-0.5Ag scaffold with antibacterial, anti-inflammatory, and osteogenic effects holds great promise as a promising biomaterial for repairing infectious bone defects.

Zinc-chlorine (Zn-Cl 2 ) battery with high discharge voltage, attractive theoretical energy density and inherently low-cost active materials provides affordable and scalable solutions for stationary energy storage. However, the Zn-Cl 2 battery suffers from rapid capacity decay and low coulombic efficiency (CE), primarily due to uncontrolled overflow of Cl 2 gas from the electrolyte. Solvents with high chlorine solubility like CCl 4 combine high chlorine storage capacity, delivering a theoretical volumetric capacity of up to 97 Ah L −1 , but at the cost of suffering from water-oil interfacial instability. In this work, we designed a wettability-tailored membrane electrode with CNT and Pt nanoparticle that stabilizes the two-phase interface and exhibits electrocatalytic activity. Moreover, leveraging the abundant and low-cost chloride in seawater, we replace deionized water with seawater. When using a seawater-based electrolyte, the Zn-Cl 2 flow battery delivers 600 stable cycles (over 220 h) with an average CE of 88.37%. Notably, it maintains 1420 stable cycles (over 544 h) at 0 °C, accompanied by an average CE of 91.94% and a capacity retention of 94.1%. This work establishes a new paradigm for the design of interface regulation strategies in Zn-Cl 2 flow batteries, providing a feasible approach for high-capacity, seawater-based energy storage systems suitable for coastal low-temperature applications.

P2-type layered oxide cathode materials suffer from severe challenges for practical application in sodium-ion batteries (SIBs), such as irreversible detrimental phase transitions, sluggish Na + diffusion kinetics, and poor air stability. To address these issues, a dual-site synergistic doping strategy is rationally designed and implemented in this work, enabling the successful synthesis of the P2-Na 0.65 Ni 0.09 Fe 0.16 Mn 0.67 Cu 0.05 Zn 0.05 O 2 (NFMCZO) cathode material. Atom-level energy-dispersive X‑ray spectroscopy (EDS) mapping directly confirms the precise dual-site occupation of Cu/Zn. Specifically, Zn 2+ occupies the Na sites to form a “pillar effect” to stabilize the interlayer structure, prevent the intrusion of H 2 O and CO 2 , and hinder transition metal (TM) migration. Meanwhile, both Zn 2+ and Cu 2+ are doped into the TM layer, which strengthens the TM–O bonds, avoids cracks, and expands the Na + transport pathways. Ex-situ X-ray diffraction (XRD) results further demonstrate that the detrimental P2-O2 phase transition is effectively suppressed during repeated charge-discharge cycling. Benefiting from the synergistic doping effect, the NFMCZO cathode shows excellent electrochemical performance. It achieves a capacity retention of 75.16% after 200 cycles at 1 C, along with outstanding rate capability (78.36 mAh g −1 at 5 C) and remarkable air stability (almost no structural change after 30 days of exposure). This work provides feasible design insights into the development of SIBs with long cycling life and excellent air stability, which can be extended to the construction of more stable layered oxide compounds and further promote the enhancement of their electrochemical performances. Cu/Zn dual-site-specific synergistic doping stabilizes P2-type layered oxide cathodes, in which Zn acts as an interlayer pillar to expand the Na + transport pathway; meanwhile, both Cu and Zn strengthen TM–O bonds to inhibit phase transitions, thus enabling fast Na + diffusion, excellent cycling stability, and exceptional air stability.

The long-term clinical success of titanium-based implants is perpetually compromised by post-operative infection and suboptimal osseointegration. To address this dual challenge, we developed a defect-engineered, zinc-doped titania (Zn-TiO 2-x ) coating through a two-step process of micro-arc oxidation and subsequent alkaline reduction. This process endows the material with a profusion of oxygen vacancies (OVs), imparting significant absorbance in the near-infrared (NIR) spectrum. Upon 808 nm laser irradiation, this property translates into highly efficient photothermal conversion, which orchestrates a formidable, multi-modal antibacterial assault. The coatings exhibited exceptional bactericidal efficacy, achieving eradication rates of over 89% against S. aureus and 98% against E. coli . This potency stems from a synergistic trinity of hyperthermia via photothermal therapy (PTT), cytotoxic reactive oxygen species (ROS) generated through photodynamic therapy (PDT), and the intrinsic antimicrobial activity of released Zn 2+ . Concurrently, beyond antimicrobial prowess, the hierarchical porous microarchitecture acts in concert with the pro-osteogenic bioactivity of Zn 2+ to markedly enhance the adhesion, proliferation, and osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs). This study presents a versatile coating strategy for endowing titanium implants with dual therapeutic capabilities, opening new avenues for smart implants that actively combat infection and promote tissue regeneration.

Hierarchical three-dimensional (3D) porous architectures are critical for overcoming mass-transfer limitations in catalytic CO 2 conversion, yet their scalable integration with atomically dispersed active sites remains challenging. Herein, we report a facile precursor-anchoring strategy to fabricate monolithic Zn, N, O-codoped porous carbon (ZnNC-900) via carbonization of melamine sponge uniformly coated with a Zn 2+ -polydopamine layer. The melamine sponge provides a continuous 3D macroporous network that facilitates efficient reactant flow, whereas dopamine-mediated chelation generates Zn and N sites along with oxygen functionalities. This unique structure not only enhances the adsorption and activation of both CO 2 and epoxides but also enables a pronounced synergistic photothermal-photocatalytic effect under light irradiation. Under mild conditions of either thermal (80 °C, 0.1 MPa) or room-temperature light irradiation (350 mW/cm 2 ), ZnNC-900 achieves a high yield of >99% within 12 h for CO 2 cycloaddition with epichlorohydrin. Furthermore, the catalyst displays robust stability and broad substrate tolerance, underscoring its practical potential for CO 2 fixation.

Aqueous rechargeable Zn-organic batteries at discharged state can self-charge through the spontaneous O 2 -oxidation of organic cathode, and the self-charged energy originates from the consumption of Zn anode, as the stripped Zn is converted into complex compounds on cathode surface. These byproducts block ion diffusion and shorten cycle life. Additional drawbacks include the semi-open battery case for air uptake, which leads to electrolyte evaporation, and the low discharge voltage plateau. To address these challenges, herein a triple strategy is presented: (i) The fabrication of a bicomponent organic cathode comprising a polymer and small molecules, achieving a synergistic effect by the regulation of molecular orbital levels; (ii) The incorporation of Pt nanoparticles into the organic blend to modulate redox reactions, thereby enhancing capacity and enabling self-charging capability based on proton chemistry, without the O 2 -oxidation mechanism; (iii) The implementation of an electrolyte decoupling strategy, which not only elevates the self-charged voltage to 2.1 V but also prevents byproduct formation on cathode surface. The hermetically sealed cell can self-charge to generate power by consuming the Zn anode. The role of Pt nanocatalyst in augmenting capacity and self-charging performance is investigated both experimentally and theoretically. Furthermore, practical applications of this self-charging battery are vividly demonstrated.

High-entropy single-atomic sites (HESAs) outperform single atomic sites (SAs) by high mixed-entropy, modulated atomic configuration and promoted oxygen adsorption. Herein, we report the design of high-entropy single-atomic sites (FeCoNiMnCu HESA) that are anchored on the macroporous carbon nanofiber (NMCF) to fabricate highly efficient (HESA@NMCF) catalysts for oxygen reactions. Theoretical calculations results reveal that the high-entropy heteroatoms play an important role in decreasing the symmetry of electronic structure of carbon substrate and modulating the adsorption capability of oxygen intermediate, which contribute to the boosted electrocatalytic performance. Electrochemical test results reveal the HESA@NMCF catalyst with HESA sites and macroporous substrate shows the superior catalytic properties, fast kinetics, and good stability. In particularly, it exhibits the pH-universal oxygen reduction properties with the higher half-wave potentials (E 1/2 ) of 0.920 V, 0.800 V and 0.631 V vs. RHE in alkaline, acidic, and neutral electrolytes over the Fe-SA@NMCF counterpart that only has Fe single-atom site. Moreover, Zn-air battery with HESA@NMCF cathode shows a high power density of 236.1 W kg −1 and a long lifespan over 900 h cycling. Combined with the anti-freezing hydrogel electrolyte, the quasi-solid-state Zn-air batteries show a superior high-rate long-term cycle life over 400 h at 20 mA cm −2 , a smooth operation over a wide-temperature range, and an outstanding low-temperature adaptation with 240 h stable cycling at −40 °C. Therefore, this work presents a novel strategy on engineering the electronic structure and modulating the local environment for HESAs. It gives a new clue to design pH-universal electrocatalysts for a wide range of applications, such as metal-air batteries, fuel cells, water splitting, etc.

Nickel/cobalt-based materials have attracted significant interest as cathode materials for aqueous alkaline Zn batteries (AAZBs) due to their high theoretical capacity and natural abundance. However, their practical application is hindered by unsatisfied discharge capacity and poor cycling stability, primarily caused by insufficient active sites and sluggish reaction kinetics. Herein, an effective approach is demonstrated to achieve high-efficiency and stable cathode for AAZBs by anchoring the NiCo 2 S 4 /Co 9 S 8 heterostructures on MXene nanosheets (NCS/CS@MXene), accompanied with morphological optimization. The introduced MXene significantly increases the effective active area and electrical conductivity of the composite. Consequently, the NCS/CS@MXene//Zn battery delivers a high areal capacity of 1.01 mAh cm −2 at 2 mA cm −2 , excellent cycling stability of 2500 cycles with only 0.00416% of capacity degradation per cycle, and nearly 100% coulombic efficiency.

Zr-Zn/ZnO catalyst was synthesized for microwave-assisted PET glycolysis. • Atomic-level Zr incorporation regulates Zn coordination environments and Lewis acidity. • Near-quantitative recycling of PET waste was achieved. • Synergistic Zn Zr sites facilitate PET glycolysis toward high-purity BHET (99.8%). • This strategy can potentially be applied to diverse real-world PET waste. Closed-loop recycling of polyethylene terephthalate (PET) into bis(2-hydroxyethyl) terephthalate (BHET) monomers represents a promising approach to plastic waste valorization, yet its application is constrained by low monomer purity and limited feedstock compatibility. Herein, a high-performance Zn-Zr/ZnO catalyst was synthesized via a simple impregnation method. Under microwave-assisted glycolysis conditions, this catalyst enables the conversion of PET to BHET with a yield of 94.2% and purity of 99.8%. The system demonstrates stable recyclability over 10+ reaction cycles and reduces energy consumption by 60% in the depolymerization process compared with conventional electric furnace-based thermal catalysis. The recovered BHET can be repolymerized into a PET-like polymer, establishing a closed-loop material cycle. Notably, the method achieves efficient monomer conversion across a range of real-world PET plastics and fiber products, with successful implementation in a 150-g scale-up experiment. Mechanistic studies indicate that Zr and Zn species synergistically promote PET depolymerization to BHET. This work presents an efficient and stable route for high-value closed-loop recycling of waste PET, which could support the advancement of the plastic circular economy.

In-situ 1 T/2H MoS 2 heterointerfaces synergistically combine 2H light-harvesting with 1 T conductivity for enhanced charge separation. • Optimized MoS 2 features expanded interlayer spacing and abundant active sites, accelerating Zn 2+ diffusion and redox kinetics. • The PRZIB delivers 340 mAh g −1 under illumination (vs. 237 mAh g −1 in dark) and achieves 1.2% photoconversion efficiency. • Photo-recharging couples Zn 2+ extraction with photoelectron-driven Zn deposition, while flexible devices demonstrate stable power output for LEDs. Photo-rechargeable Zn-ion batteries (PRZIBs) are constrained by photocathodes lacking efficient light harvesting, fast transport, and reversible Zn 2+ storage. Herein, we develop a temperature-controlled hydrothermal strategy to construct in-situ 1 T/2H MoS 2 photocathodes with tunable interlayer spacing and defect density. The optimized sample synthesized at 140 °C exhibits enlarged interlayer spacing, abundant active sites and an intimate 1 T/2H phase interface, which accelerate Zn 2+ diffusion and redox kinetics. Moreover, the semiconducting 2H domains absorb light while metallic 1 T domains extract photogenerated electrons, enabling synergistic charge separation. Consequently, the PRZIB achieves a photoconversion efficiency of 1.2% and a discharge capacity of 340 mAh g −1 under illumination, versus 237 mAh g −1 in the dark at 0.1 A g −1 . Mechanistically, quasi-in-situ XRD reveals that photo-recharging couples Zn 2+ extraction with photoelectron-driven Zn deposition, while discharge reverses via intercalation/stripping, as confirmed by reversible (002) reflections. Additionally, flexible devices demonstrate stable power output, driving a biomimetic bird and an LED. Overall, this work highlights heterophase junction engineering as a promising route for integrated photo-rechargeable systems.
