A series of nickel phyllosilicate catalysts (Ni-PS-T, where T represents the calcination temperature in °C) were synthesized via he ammonia-evaporation method and calcined at different temperatures to investigate their performance in the hydrogenation of 5-hydroxymethylfurfural (HMF). Characterization by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM) revealed that increasing the calcination temperature (300–1100 °C) triggered a phase evolution from the 1:1-type (tetrahedral-octahedral) to the 2:1-type (tetrahedral-octahedral-tetrahedral) Ni-PS, eventually leading to phase separation into NiO and SiO2. The content of the 2:1-type crystalline phase, H2adsorption capacity, and C=O hydrogenation activity of HMF all exhibited a volcano-shaped trend with calcination temperature. Under the conditions of 100 °C and 2.5 MPa H2, Ni-PS-800 enabled HMF hydrogenation with a conversion of 90% and a selectivity of 84% to 2,5-dihydroxymethylfuran (DHMF), in which the catalyst exhibited good stability during five consecutive HMF hydrogenation cycles. The enhanced catalytic performance of Ni-PS-800 is attributed to its high 2:1-type phase fraction, which promotes a pronounced hydrogen-spillover effect and significantly enhances the intrinsic activity for C=O hydrogenation.

Direct seawater electrolysis offers a sustainable pathway for large-scale hydrogen production but is fundamentally limited by chloride-induced corrosion, parasitic chlorine chemistry, and rapid catalyst degradation at industrial current densities. Here, we report a Ru-doped Ni-based-layered double hydroxide integrated with a pyrolyzed wood-derived carbon scaffold (NiRu-LDH@pWD) that addresses these issues through synergistic electronic structure and electrode architecture engineering. Ru doping reconfigures the local electronic environment of Ni, strengthens Ni–O coordination, downshifts the d -band center, and suppresses Cl∗ adsorption, thereby enhancing catalytic selectivity and stability in chloride-rich electrolytes. Concurrently, Ru doping induced lattice modulation promotes preferential exposure of catalytically active (012) edge planes. The hierarchically porous pWD carbon scaffold enables rapid charge transport, efficient ion diffusion, and superaerophobic gas release, sustaining high-rate operation. As a result, the NiRu-LDH@pWD electrode delivers low overpotentials for HER (74.7 mV in 1 M KOH and 101.1 mV in seawater) and OER (240 mV in 1 M KOH and 260 mV in seawater) at 10 A cm −2 , and exhibits >1000 h operational durability at 1 A cm −2 in seawater. An anion exchange membrane water electrolyzer assembled with NiRu-LDH@pWD achieves a low cell voltage of 2.01 V at 1 A cm −2 with negligible performance decay, meanwhile techno-economic analysis estimates a competitive hydrogen production cost of ∼US$0.35 kg −1 by ASPEN calculation. This work establishes an integrated strategy that couples atomic-scale electronic regulation with macroscopic electrode design to enable selective, durable, and economically viable seawater electrolysis.

Achieving near-zero internal stress without sacrificing strength remains a key challenge in Ni-based electroforming. Here, a Co/BSA co-regulation strategy is developed using benzenesulfonamide (BSA) as a dual-functional additive. Theoretical calculations and electrochemical measurements show that the benzene ring promotes interfacial adsorption, while activation of the sulfonamide group facilitates S incorporation, shifting the internal stress from tensile to compressive. Dynamic BSA adsorption suppresses lateral and through-thickness grain growth, promotes nucleation, and drives the transition from columnar grains to refined equiaxed grains. Meanwhile, facet-dependent BSA adsorption drives a concentration-dependent texture transition by shifting the deposition mode from grain-growth-dominated at low BSA concentrations to nucleation-dominated at high concentrations, favoring (200)- and (111)-oriented grains, respectively. The resulting texture evolution and S segregation cause a mismatch between the low-stress and high-hardness windows. To overcome this trade-off, Co is introduced for synergistic regulation. Co incorporation provides tensile-stress compensation and solid-solution strengthening, shifting the near-zero-stress state toward the high-strength region. Consequently, Co/BSA co-regulation enables the fabrication of near-zero-stress Ni-Co deposits with a hardness of 549.3 HV 0.1 and a tensile strength of 1598.2 MPa. This work provides a strategy for designing low-stress and high-strength electroformed Ni-based materials.

A synergistic dealloying and heterojunction construction strategy is developed on crystalline Ni–Fe–P ribbons. • The strong heterointerface enables efficient interfacial charge transfer and exposes abundant active sites for OER. • The electronic structure and surface reconstruction of the ribbon are modulated via LDH-induced interfacial coupling. Ni-Fe based ribbons are promising self-supporting oxygen evolution reaction (OER) electrocatalysts due to their low cost, good conductivity, and high intrinsic activity. However, pristine ribbons exhibit poor OER performance because their smooth, non-porous surface leads to limited active sites and their sluggish surface reconstruction lowers intrinsic activity. Dealloying can create nanoporous structures, but this single strategy suffers from a trade-off between mechanical integrity and active area, as well as a depth limitation of the porous layer (~500 nm). Herein, we report a synergistic strategy combining mild dealloying pretreatment with in situ growth of NiFe-LDH on Ni-Fe-P ribbons. Moderate dealloying preserves mechanical robustness while providing a nanoporous anchoring layer. Subsequent growth of NiFe layered double hydroxide (NiFe-LDH) nanosheets compensates for the limited active area, builds a deep three-dimensional catalytic network beyond the dealloying-limited depth, and forms a strong heterointerface that facilitates charge transfer. The optimized Ni-Fe-P/LDH electrode achieves a low overpotential of 245 mV at 20 mA cm −2 , substantially outperforming the pristine ribbon (353 mV) and the solely dealloyed ribbon (267 mV), and maintains stable operation for over 100 h at 10 mA cm −2 and 50 h at 500 mA cm −2 . This work demonstrates the feasibility of combining dealloying and heterojunction engineering for high-performance self-supporting OER electrocatalysts.

Electrocatalytic nitrate reduction to ammonia (NO₃RR) offers a promising route for wastewater treatment and nitrogen resource recovery. In this work, a FeNi alloy-loaded carbon material (FeNi-C) was evaluated about NO 3 RR performance and the role of different active hydrogen (H*) was illustrated. FeNi(1:1)-C obtained at 700 °C exhibits a 96.6% NO 3 ⁻ -N removal and 99.6% NH₄ ⁺ -N selectivity at −1.5 V and it maintains excellent performance over 10 cycles without metal leaching. Furthermore, high-concentration nitrate can be converted to ammonium, recovered as struvite. Mechanism analysis indicate that a high surface coverage of adsorbed atomic hydrogen (H* ads ) is more crucial for enhancing the selectivity of nitrate-to-ammonia conversion compared with the free H*（H* free ）in the electrolyte. Tafel slope combined with verification experiments reveal that an optimal Ni 0 /Ni 2+ (≈2) facilitates water electrolysis to enables FeNi(1:1)-C forming a high surface coverage of H* ads . Thereby, FeNi(1:1)-C maintains an abundant H* ads -covered reductive-microenvironment surface, promoting fast conversion between H* ads and the adjacent nitrogen-containing intermediates and suppressing the competing hydrogen evolution reaction (HER). Furthermore, this reductive-microenvironment surface also helps protect the FeNi alloy from oxidation, endowing its superior stability. This work highlights the superior role of H* ads over H*（H* free ）in the electrolyte.

The development of aqueous aluminum metal batteries is hampered by severe parasitic side reactions at the aluminum metal anode/electrolyte interface. In this work, aluminum-based amorphous alloy anodes are applied to aqueous aluminum metal batteries for the first time. Amorphous aluminum alloys exhibit higher adsorption energy for Al atoms and can regulate the Al 3 + deposition potential, thereby offering a kinetic advantage over the hydrogen evolution reaction. Their isotropic deposition behavior suppresses aluminum dendrite growth, while the amorphous structure also improves interfacial chemistry, mitigating anode self-corrosion and passivation. The coupling between the adsorbed atoms and the Al 85 Ni 10 Ce 5 substrate electrons is stronger, leading to more stable adsorption. Symmetric cells assembled with Al 85 Ni 10 Ce 5 amorphous alloys demonstrated stable cycling for 5000 h, which present the best cycling performance for bare anode for aqueous aluminum metal batteries at 0.1 mA cm −2 and 0.1 mAh cm −2 . Moreover, a full cell incorporating this anode with a K 2 CoFe(CN) 6 cathode delivered a high initial discharge capacity of 98.3 mAh g −1 . This work provides not only a scalable strategy for high performance aqueous aluminum metal batteries, but also theoretical guidance for the electrode optimization of other metal battery systems.

The primary limitations of the oxygen evolution reaction (OER) electrocatalysts stem from poor electrical conductivity and insufficient accessibility of active sites. So highly productive catalysts are vital to lower the overpotential and enhance the kinetics of the sluggish OER. In this work, we present an effective OER electrocatalyst (NiS/N-CNT@Ni) and composites of Ni nanoparticles encapsulated in NiS/N-CNT fabricated via a simple two-step thermal treatment method. Meanwhile, due to the synergistic effect between NiS and nitrogen-doped carbon nanotubes (CNTs) and Ni, the NiS/N-CNT@Ni composites show higher OER electrocatalytic activity and better durability than commercial RuO 2 catalysts. Compared to commercial RuO 2 , the NiS/N-CNT@Ni catalyst demonstrates a lower overpotential (313 mV at 10 mA cm −2 ) and better stability. This study confirms that the NiS/N-CNT@Ni material not only exhibits a low overpotential but also presents a scalable, cost-effective synthesis strategy for high-performance composites applicable to energy conversion and storage.

Among CO 2 emission mitigation strategies, the reverse water-gas shift (RWGS) reaction represents a promising route for selective CO 2 -to-CO conversion, enabling subsequent valorization. However, designing selective and stable non-noble metal catalysts for RWGS remains a persistent challenge. In this study, we report a Ni site-induced localized accelerated carbonization process to produce noble metal-like active Ni-WC nano-islands for high-performance RWGS catalysis. Benefiting from the unique structures, the Ni 0.02 WC/WO 2 -NIs catalyst exhibits exceptionally high RWGS activities, with a CO production rate of 2340 mol CO ·mol WC -1 ·h -1 and over 97% CO selectivity. Even after 100 hours of continuous testing at 500 °C, the activity loss of Ni 0.02 WC/WO 2 -NIs was only 0.5%. Unlike the conventional catalyst structure in the RWGS reaction, we demonstrate that the nano-island WC structure with stretch strain ensures the space limitation of electron-rich Ni sites for CO desorption and H 2 dissociation. Integrated in-situ DRIFTS, Raman spectroscopy, and DFT calculations reveal that dual-functional WC/WO x interfaces enhance catalyst activity through bidentate carbonate formation and intensified hydrogen spillover. We suggest that the design of new, efficient, and selective Ni-based noble-metal-like catalysts with nano-island structure through interface synergistic effects offers a promising path to engineering superior RWGS catalysts for CO 2 reduction.

Core–shell microspheres with a supporting polymer core and conductive shell emerge as effective fillers for anisotropic conductive films (ACFs) that are widely used in high-precision interconnection of miniaturized electronics. Conventional methods for synthesizing such conductive microspheres usually require the use of hazardous sensitizers, which severely hinder their scalable and environmentally friendly production. Herein, an economical strategy is developed to facilely synthesize core–shell conductive microspheres by using bi-functional amine polychloromethylstyrene (PCMS) as the substrate. The amino groups of PCMS can undergo cross-linking with ethylenediamine, thereby endowing the microspheres with excellent structural stability in organic solvents. Simultaneously, the strong anchoring effect of the amino groups facilitates the formation of ultrafine Pd nanoparticles on the surface, which serve as catalytic sites for the subsequent electroless deposition of Ni layer with an adjustable thickness (100–400 nm). Due to the uniform size, high electrical conductivity, and robust mechanical stability of PCMS@Ni microspheres, the fabricated ACFs exhibit excellent pressure-sensitive conductive performance and anisotropic conductivity, enabling high-resolution display and a wide color gamut in liquid crystal devices. Furthermore, the versatility of this functionalization strategy is demonstrated by extending the deposition to other metals, such as Ag and Au, highlighting its broad applicability in advanced electronic materials.

Ethanol steam reforming (ESR) enables renewable biomass-derived H2 production but suffers from selectivity and deactivation challenges. While CeO2-supported metal catalysts are widely explored for ESR owing to strong metal–support interactions and inherent oxygen storage capacity, persistent ambiguities in facet-dependent performance arise from methodological constraints in decoupling intrinsic facet effects from metal particle size variations. By synthesizing morphology-controlled CeO2 supports exposing distinct facets ({100}, {110}, {111}) and anchoring size-uniform Ni nanoparticles (∼2 nm), we decoupled facet contributions to reveal how facet-specific Lewis acidity governs OH* reactivity at Ni–CeO2 interfaces. Combined kinetic assessments, in situ spectroscopy, and density functional theory identify α-C–H abstraction from CH3CH2O* by interfacial OH* as the kinetically relevant step, with acetate intermediates directly formed from CH3CH2O* (not acetaldehyde) facilitating C–C bond scission under steam-rich conditions. Ni supported on {100}-rich CeO2 nanocubes enhances OH* reactivity via weakened Lewis acidity, lowering acetate formation barriers. This facet-modulated interfacial chemistry achieves 426 mmol gcat–1 h–1 H2 formation rate and 72.1% CO2 selectivity at 400 °C, surpassing literature benchmarks under comparable conditions. These findings elucidate how facet-dependent interfacial chemistry dictates ESR performance on Ni/CeO2 catalysts, providing mechanistic insights beyond conventional oxygen storage capacity correlations.

Development of electrocatalytic reduction of carbonyl compounds for carbon‑carbon (C C) coupling represents an effective pathway to achieve sustainable synthesis of multi‑carbon chemicals. The hydrogen evolution reaction (HER) is considered the most significant competitive process, which could be suppressed by weakening the adsorption of protons on interface or by making protons in the electrolyte inactive through the use of certain additives. However, increasing the coverage of protons and carbonyl molecules are necessary to facilitate the generation of hydrogenation intermediates during C C coupling. To reconcile this contradiction, a Ni-based catalyst for electrocatalytic coupling of formaldehyde has been developed, decorated with phosphate groups around Ni sits. The following enhancement could be achieved: 1) Ni sites enhance the adsorption of formaldehyde on catalyst surface and promote their electroreduction; 2) Phosphate groups near the Ni sites can act as protons affinity sites to prevent their self-coupling. As the result, the adsorbed HCHO and hydrogen can be balanced to facile the formation of intermediate *CH 2 OH during C C coupling. Consequently, the PD-Ni/C@CP catalyst exhibits outstanding performance in the continuous preparation of ethylene glycol, with a production rate of 22 mmol/(L·min) and a Faradaic efficiency exceeding 90%, highlighting its potential for the efficient and sustainable synthesis of other high-value chemicals.

Achieving tunable, high-performance electrical and electromagnetic properties in polymer-based composites remains challenging due to insufficient understanding of the relation between particle structure, surface conduction, and internal tunneling in segregated networks. Here, a multi-scale strategy is presented to elucidate and optimize the electrical conduction mechanisms in nickel-coated polyethylene terephthalate (PET@Ni) composite films with segregated network systems. Composite films with controlled particle size and tailored Ni shell thickness were fabricated via electroless plating and sequential hot pressing. The conductive network architecture governed transport behaviors. Surface conduction dominated in thin films, while interparticle tunneling dominated in thick configurations. A multi-level theoretical model was developed. Relaxation dynamics and quantum mechanical corrections based on density functional theory were incorporated. The proposed model describes the observed conductivity behaviors with high accuracy (R² > 0.98). Finite element simulations further confirmed the spatially heterogeneous current densities and electric field intensities. Microcapacitive behavior was enhanced in films with smaller particles due to increased Ni shell connectivity. Dual-layer structures provided additional tunability. Secondary Ni plating boosted electromagnetic interference (EMI) shielding up to 63.77 dB. A robust structure-property framework was established. These results offer new design principles for scalable, multifunctional polymer-based composites in advanced electronics, EMI shielding, and next-generation sensing systems.
