The rational design of electrocatalysts with high catalytic activity and outstanding corrosion resistance is of great significance for achieving water/seawater oxidation. In this work, a three-dimensional microrod C, N-FeNbO 4 /NF was successfully synthesized for the first time via hydrothermal approach integrated with in-situ strategy to construct more 001 crystal planes. Specifically, fluoride ions (F − ) coordinate with Fe/Nb and selectively adsorb onto FeNbO 4 (001) crystal plane. During liquid-phase nucleation process, the oxide further crystallizes along z-axis into microrod. Furthermore, the abundant C and N sources from solutions are incorporated into FeNbO 4 lattice by in-situ doping, thus significantly enhancing intrinsic electrical conductivity and catalytic activity. Meanwhile, the C, N-FeNbO 4 deposits on largely conductive nickel foam (NF), offering water/seawater oxidation under high current density. According to density functional theory (DFT) calculations, the model of in-situ constructed C, N-FeNbO 4 (001) crystal plane displays large carrier concentration and more mobile electrons. In-situ infrared spectroscopy suggests that C, N-FeNbO 4 /NF hosts multiple types of catalytic active sites, and confirms oxygen evolution reaction (OER) progress by adsorption evolution mechanism. From in-situ differential electrochemical mass spectrometry, the OER product of C, N-FeNbO 4 /NF is O 2 ( m / z = 32), showing large O 2 evolution efficiency. The “in-situ derivatization–functional synergy” strategy imparts good electrocatalytic performance to C, N-FeNbO 4 /NF. In 1 M KOH and natural seawater, their overpotentials, with just 325 mV and 339 mV individually, can be acquired under 100 mA cm −2 current density. Depending on Tafel curve, the C, N-FeNbO 4 /NF offers strong corrosion resistance (corrosion potential: −0.17 V). Besides, it retains 96.5% initial activity after operating 100 h at 100 mA cm −2 current density in natural seawater.

A Ni 2 P layer on Ni nanorod arrays is used to elucidate the dynamic coupling between alcohol oxidation (AOR) and oxygen evolution (OER). A cooperative region (1.50–1.56 V vs. RHE, [OH − ] < 2.0 M) boosts both TOF AOR and TOF OER , whereas a competitive region at higher potential/alkalinity suppresses AOR and compromises overall anodic performance. In situ Raman identifies NiOOH as the common active phase and reveals a complementary mechanism: OER enables NiOOH activation, while AOR drives NiOOH ordering and stabilizes the reconstructed interface, thereby mitigating Ni 2 P corrosion and sustaining higher currents. These insights provide practical guidance to engineer robust, low-energy, value-added anodes via controlled AOR-OER coupling.

Dual-atom catalysts (DACs) show great promise in catalyzing oxygen reduction/evolution reactions (ORR/OER), yet facing significant challenges in achieving simultaneous high catalytic activity and stability in zinc–air batteries (ZABs). In this study, we synthesized a porous three-dimensional carbon aerogel anchored with atomically isolated FeN4/NiN4 dual sites and Ru6 nanoclusters (FeN4–Ru6–NiN4@PCA) to address these challenges. The adjacent Ru6 nanoclusters effectively regulate the geometric structures of FeN4 and NiN4 sites and catalyze the formation of a highly graphitic carbon matrix. These structural features endow FeN4–Ru6–NiN4@PCA with remarkable ORR/OER activity and stability, outperforming counterparts with only FeN4/NiN4 dual species and benchmark Pt/C and RuO2 catalysts. Density functional theory calculations reveal that Ru6 clusters induce obvious electron redistribution of FeN4/NiN4 sites and optimize their electron transfer to the key oxygen intermediates (OH*) at the rate-determining steps, thereby accelerating the ORR and OER kinetics. When employed FeN4–Ru6–NiN4@PCA as the cathode catalyst in ZABs, the resulting ZAB delivers a peak power density of 197.76 mW cm–2 and demonstrates outstanding cycling stability over 2000 h, highlighting its great potential for use in applications of energy storage device.

The catalytic upcycling of plastic mixtures into H 2 and carbon nanotubes (CNTs) represents a transformative strategy for advancing plastic management and the circular economy. Herein, an in-situ constructed high-performance FeNi/Ni/C catalyst combined with prompt microwave catalysis enables efficient conversion of LDPE-PVC, LDPE-HDPE-PP-PS-PVC-PTFE and landfilled waste mixture into valuable H 2 and CNTs, resulting in near-quantitative atom economy (i.e., H 2 and carbon efficiencies are nearly 100%) together with H 2 and CNTs yields reaching >922 mmol g -1 catalyst and >10600 mg g -1 catalyst , respectively. Furthermore, this microwave catalysis strategy presents an excellent stability (>35 cycles) via Cl/F-based regeneration and energy efficiency (80% reduction vs. traditional thermal catalysis), alongside a high turnover number of 107.6 mol carbon mol -1 NiFe . Fundamentally, the Ni species contribute to C-H breaking, and Fe is beneficial for CNT formation during plastic decomposition. Here, we show a cost-effective platform for upcycling of chlorinated/fluorinated plastic mixtures, aligning with resource circularity objectives.

Ni/CaCeO x achieves efficient integrated CO 2 capture and dry reforming of methane. • CeO 2 reduces the CO 2 capture temperature and facilitates its conversion at 600 °C. • Ni/Ca 0.6 Ce 0.4 O x -R demonstrated an H 2 yield of 63.67 mmol/g DFMs and a CO 2 conversion exceeding 95% at 600 °C. • Reverse Boudouard reaction plays a critical role in facilitating CO 2 conversion. Integrated CO 2 capture and conversion (ICCC) using CaO based adsorbents is a promising method for industrial carbon reduction, but its application is constrained by challenges such as high operating temperatures, CaO sintering, carbon deposition on Ni sites. In this work, CeO 2 was introduced into Ni/CaO to synthesize Ni/CaCeO x dual-functional materials (DFMs) with regulated oxygen vacancies. By tailoring the morphology of CeO 2 the oxygen vacancy concentration and capture-conversion performance were effectively tuned. The incorporation of CeO 2 significantly promoted low-temperature CO 2 uptake and reduced the activation energy of dry reforming of methane (DRM) reaction, lowing the operating temperature by more than 50 °C compared to previously reported ICCC-DRM studies. Among the prepared materials, the CeO 2 -introducted and reduced Ni/Ca 0.6 Ce 0.4 O x -R catalyst showed the best performance, reducing the CO 2 uptake temperature from the theoretical 600 °C to 410 °C. Under isothermal ICCC conditions at 600 °C, it achieves H 2 and CO production rates of 63.65 mmol/g DFMs and 56.74 mmol/g DFMs , respectively, while carbon elimination reached 35.06 mmol/g DFMs . Notably, the DFM exhibits excellent cycling stability, with only 10.08% loss in H 2 yield and 8.40% loss CO 2 conversion after 10 cycles. This work demonstrates that oxygen-vacancy control by CeO 2 modification is an effective route to improve the efficiency and stability of CO 2 capture and conversion.

PAMD strategy stabilizes Ni nanoparticles on graphene oxide supports. • Ni–GO shows superparamagnetism for facile magnetic separation and reuse. • 95% 4-NP conversion in 2 min with first-order rate constant 3.02 × 10 −2 s −1 . • Continuous-flow reactor runs 12 h at 5 mL min −1 keeping >90% conversion. • Catalyst retains 90% activity after 2100 cycles with stable structure. A polymer-assisted metal deposition strategy is developed to fabricate nickel loaded graphene oxide (Ni-GO) composites with enhanced catalytic stability. GO is first functionalized via silane coupling and surface polymerization, creating effective anchoring sites for uniform Ni nanoparticle deposition. The resulting Ni-GO composite exhibits superparamagnetic behavior with a saturation magnetization of 6.75 emu g −1 , enabling rapid magnetic recovery. In batch reduction of 4-nitrophenol, the catalyst achieves over 95% conversion within 2 min and follows first-order kinetics with a rate constant of 3.02 × 10 −2 s −1 at 30 mg catalyst dosage. A continuous-flow reactor packed with Ni-GO maintains >90% conversion for 12 h at 5.0 mL min −1 . Scale-up configurations including series and parallel assemblies demonstrate stable performance up to 50 mL min −1 . The composite also effectively degrades methyl orange, rhodamine B and methylene blue, and hydrogenates various nitroaromatic compounds with >80% conversion. After 2100 catalytic cycles, the material retains 90% efficiency with negligible structural change. This work offers a practical route to stable non-noble metal catalysts for continuous pollutant treatment. A polymer-assisted metal deposition method anchors Ni nanoparticles on functionalized GO, yielding a magnetic catalyst that reduces 4-nitrophenol in 2 min, sustains >90% conversion for 12 h in continuous flow, and retains 90% activity after 2100 cycles.

This work introduces nickel (II) tetraphenylporphyrin (NiTPP) as a multifunctional electrolyte additive to simultaneously address polysulfide shuttle and uncontrolled lithium dendrite growth in lithium–sulfur (Li–S) batteries. Mobile NiTPP species act as homogeneous catalysts with Ni–N 4 centers for rapid polysulfide redox mediation to suppress migration, while planar molecules featuring lithium-affinity capability migrate to the lithium metal surfaces, enabling uniform lithium flux and anode protection. NiTPP-modified electrolytes significantly enhance Li–S battery performance, demonstrated by 634.9 mAh g −1 at 4C, 758.3 mAh g −1 after 100 cycles at 0.2 C (83.4% retention), and 757.5 mAh g −1 under high sulfur loading (2.9 mg cm −2 ) with lean electrolyte ( E / S = 5 μL mg −1 ), all with high Coulombic efficiency. Crucially, NiTPP, acting as a soluble dual-functional mediator enabling homogeneous operation in electrolytes, simplifies Li–S battery fabrication while demonstrating the commercial viability of molecularly engineered mobile active sites for stabilizing both electrodes in high-energy-density Li–S batteries.

Lignin catalytic hydrogenolysis offers a promising route to yield aromatic and alkane fuels for sustainable aviation. However, its widespread application is hindered by the reliance on high-pressure hydrogen and aggregation of metal catalysts during hydrogenolysis processes. Self-transfer hydrogenolysis is an attractive method to depolymerize without exogenous hydrogen, but suffers from low catalytic activity and poor stability. In this study, a nickel catalyst confined on cerium dioxide (CeO 2 ) nanocrystals with oxygen vacancy (O V ) is reported for efficient hydrogenolysis of both native and technique lignin into aviation fuel precursor under a nitrogen atmosphere. The O V in CeO 2 acts as electron-deficient sites, promoting the reduction of neighboring Ni atoms to a lower valence state. These low-valent Ni species efficiently cleave C─O bonds in lignin, while the oxygen vacancies serve as anchoring sites to suppress aggregation of metallic Ni nanoparticles. The confined Ni/CeO 2 with oxygen vacancies exhibits top-level hydrogenolysis performance with an exceptional aromatic monomer yield of 42% from eucalyptus lignin and ≈20% from technical lignin, comparable to that of commercial noble metal catalysts. This work opens up new possibilities of designing efficient catalysts to depolymerize both raw wood powder and technical lignin toward aviation fuel precursor.

Microbial fuel cells (MFCs) represent an emerging energy technology that generates electricity through microbial-organic interactions, with the anode serving as a critical component for wastewater-to-electron conversion. This study focuses on developing porous iron-nickel (Fe–Ni) alloys as potential anodes for MFCs, employing electrodeposition to fabricate these anodes with systematically varied Fe/Ni ratios. Through intrinsic electrochemical performance screening, the work aims to achieve composition optimization for high-performance microbial fuel cell anodes. Multi-dimensional analysis integrating linear sweep voltammetry (LSV), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and Tafel polarization was conducted to establish structure–activity relationships and synergistic catalytic mechanisms of the alloys. Key findings reveal that compositional optimization profoundly impacts the performance of these potential anodes: the Fe 7 Ni 3 alloy exhibited significantly superior electrochemical activity compared to pure Ni, characterized by dramatically enhanced peak current density, and improved charge storage capacity. Furthermore, Fe 7 Ni 3 demonstrated minimal charge transfer resistance and excellent reaction kinetics. These results validate that bulk composition engineering of porous Fe 7 Ni 3 offers a highly promising strategy for developing potential anode materials for high-performance MFCs, effectively addressing the stability-activity trade-off inherent in conventional surface-modified anodes. This work provides a composition-driven design paradigm for bioelectrochemical systems, paving the way for future scale-up studies focusing on long-term stability and integration into wastewater treatment modules.

Sodium-ion batteries are renowned for their abundant reserves, cost-efficiency, safety, and eco-friendliness and are prime candidates for large-scale energy storage applications. The development of cathode materials plays a crucial role in shaping both the commercialization path and the ultimate performance capabilities of SIBs. To overcome the intricate synthesis challenges associated with pure-phase sodium-ion cathode materials, this study introduces an innovative and streamlined electrochemical Li+/Na+exchange process, successfully fabricating a high-capacity Ni-rich cathode material. This cathode material boasts a remarkable reversible capacity of 180 mAh g−1at 0.1 C and retains a high-rate capacity of 115 mAh g−1even at 5 C. Additionally, it exhibits exceptional cycling stability, retaining about 85% of its capacity at 1 C after 50 cycles and still maintaining a capacity greater than 60% after 100 cycles. The Na-NMA85 full cell preserves a discharge capacity of 110 mAh g−1after 100 cycles, with a capacity retention rate of 80%. This research underscores innovative strategies for designing ion-intercalation-based cathode materials that enhance battery performance, providing fresh perspectives for advancing high-performance battery technologies.

A Cu foam supported Ni Cu nanowire electrode (Ni-CuNW) was fabricated and optimized. • Ni species modulated electronic structure of Cu and redistributed surface electron. • High-efficient NO 3 − to NH 3 conversion was achieved in neutral-media conditions. • Ni-CuNW enabled ~100% NO 3 − removal with 99.5% NH 4 + -N selectivity and 95.5% NH 3 FE. • FE for NH 3 production maintained above 90% across various NO 3 − concentrations. Electrocatalytic nitrate-to-ammonia conversion has emerged as a pivotal green technology that simultaneously enables waste valorization and sustainable ammonia production, offering a promising alternative to the energy-intensive Haber-Bosch process. Herein, we reported a highly efficient Ni-decorated Cu nanowire electrode (Ni-CuNW) that exhibited remarkable electrocatalytic activity under challenging neutral media, which typically suffers from insufficient H* supply and severe competition from the hydrogen evolution reaction (HER). The optimized electrode achieved near complete nitrate removal with 99.5% NH 4 + -N selectivity and 95.5% Faradaic efficiency (FE) for NH 3 production during treatment of nitrate-laden wastewater (50 mg L −1 NO 3 − -N), and maintained an NH 3 FE of 90% even in high-concentration wastewater containing 2000 mg L −1 NO 3 − -N. An integrated reactor incorporating an in-situ ammonia recovery unit was constructed, and over 95% nitrate removal and 85% NH 3 recovery were achieved under various nitrate concentrations, demonstrating its robust practical applicability. Mechanism studies revealed that the superior performance originated from the incorporation of Ni(OH) 2 species, which modulated the electronic structure of Cu and induced surface electron redistribution. This electronic structure modulation accelerated interfacial electron transfer and strengthened the adsorption of NO 3 − and nitrogen-containing intermediates. Concurrently, Ni species incorporation selectively suppressed the competing HER at active sites, thereby endowing the Ni-CuNW electrode with exceptional FE for NH 3 production. This work presented an efficient and scalable strategy for synthesizing advanced electrocatalysts suitable for both wastewater remediation and sustainable ammonia production.

To investigate the influence of different powder addition strategies on the properties of Ag-containing lubricating coatings, NiCrAlY-Mo-Ag-Cu coatings incorporating different (Ag, Cu) powders (direct doping, core-shell structure, and powder alloyed) were fabricated via atmospheric plasma spraying. Combining characterization techniques and density functional theory calculations, the friction behavior, tribological properties, and underlying mechanisms of the three coatings were explored through constant-temperature friction tests and thermal cycling friction tests over a wide temperature range. The results indicate that the core-shell structure process helps reduce coating porosity (from 2.61% to 1.68%), but the average hardness of the coating decreased by 12.5% (230.6 HV → 201.8 HV). The alloying strategy circumvented hardness degradation, striking a balance between coating densification and mechanical robustness. At 800 ℃, a composite tribofilm comprising simple metal oxides (e.g., NiO, Cr 2 O 3 , and Al 2 O 3 ) and high-temperature lubricating phases (NiMoO 4 , Ag 2 MoO 4 , CuMoO 4 ) developed on the surface, effectively suppressing silver agglomeration and depletion. Owing to the synergy of these effects, the AgCu-alloyed coating achieved a low coefficient of friction (COF) of 0.25 at 400 ℃ and demonstrated a ∼30.9% reduction in wear rate during the 800 ℃ thermal cycling test compared to the direct-doping coating.
