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.

Electrochemical upcycling of waste PET into value-added formate • Soybean root-inspired design of symbiotic active sites • Oxygen-bridge-induced 3d-5d orbital hybridization The efficient transformation of waste poly(ethylene terephthalate) (PET) into high-value chemicals represents a pivotal strategy toward a circular plastics economy. Drawing inspiration from the cooperative nitrogen-fixation relationship between rhizobia and leguminous plants, we report a tungsten-modified nickel phosphide (W-Ni 2 P) catalyst for the selective electrooxidation of PET-derived ethylene glycol (EG) into formic acid (FA). Upon electrochemical activation, robust asymmetric W-O-Ni oxygen-bridged configurations are formed in situ, establishing cooperative catalytic centers in which W operates as an electronic modulator while Ni serves as the dominant active site. The tungsten centers display strong adsorption toward *EG and *OH intermediates, functioning as dynamic buffering sites that regulate the interfacial microenvironment and concurrently facilitate the reconstruction of Ni into highly active oxyhydroxide species. This synergistic interplay, governed by W-O-Ni-mediated 3d-5d orbital interactions, effectively reduces the kinetic barriers associated with C-H dehydrogenation and C-C bond cleavage. Consequently, the optimized W-Ni 2 P catalyst achieves a current density of 500 mA cm -2 at 1.45 V versus RHE, delivering a Faradaic efficiency of 98.9% for FA production. Moreover, an anion-exchange-membrane electrolyzer sustains stable operation for over 200 hours in authentic PET hydrolysate, highlighting the system’s practical durability, scalability, and economic potential for plastic waste upcycling.

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.

Non-thermal plasma enables ammonia synthesis under mild conditions, but net performance is often limited by inefficient use of transient reactive species and plasma-driven NH 3 decomposition. Here we demonstrate that microporous confinement becomes decisively beneficial only when coupled to metal active sites. By benchmarking Ni catalysts supported on zeolites with distinct micropore architectures (BEA, MOR, FAU) against mesoporous and nonporous analogues in a dielectric barrier discharge (DBD) reactor, FAU emerges as the most effective microporous partner and delivers markedly improved activity and energy efficiency over mesoporous benchmarks. We elucidated the origin of this advantage using targeted controls (alkaline treatment/ion exchange), plasma electrical diagnostics (Q–V analysis/ignition behavior), and N 2 /H 2 /NH 3 adsorption/desorption probing under plasma. The results support a dual role of FAU micropores: enriching plasma-generated N/H species near Ni sites via confinement-enhanced residence time, and suppressing NH 3 loss through selective uptake into plasma-inaccessible micropores. MgO basic promotion further mitigates hydrogen over-coverage on Ni, yielding 7.55 mmol·h −1 ·g cat −1 and 1.65 g NH3 ·kWh −1 , competitive with reported Ni-based DBD plasma-assisted catalysts under comparable mild conditions. These findings establish micropore–metal synergy in zeolite-supported Ni catalysts as a guiding design principle for plasma-assisted ammonia synthesis. Graphical Micropore–metal synergy in zeolite-supported Ni catalysts promotes plasma-assisted ammonia synthesis by enriching plasma-derived N/H species and suppressing NH 3 decomposition. Additional MgO promotion relieves H over-coverage on Ni, further improving the NH 3 formation rate and energy efficiency.

High-voltage degradation of Ni-rich single-crystal layered oxide cathodes (SC-NCM) is closely coupled with the cathode–electrolyte interface, where parasitic reactions, surface reconstruction, and kinetic deterioration are readily activated during deep delithiation. To clarify the role of interfacial reaction pathways in this degradation process, electrolyte additive chemistry was used as a molecular tool to regulate the initial interfacial reaction pathway without altering the bulk structure of the cathode. The results reveal that an uncontrolled interface accelerates electrolyte decomposition, charge-transfer resistance growth, Li + transport deterioration, high-voltage phase irreversibility, and layered-to-rock-salt surface reconstruction. In contrast, additive-regulated cathode–electrolyte interphase (CEI) formation stabilizes the interfacial reaction environment, suppresses parasitic surface reactions, and preserves charge-transfer and Li + diffusion kinetics during deep delithiation. Moreover, the regulated interface maintains the reversibility of the H2–H3-related phase evolution and mitigates stress concentration during the structurally sensitive phase-transition stage. This work demonstrates that regulating the initial cathode–electrolyte reaction pathway can mitigate interface-triggered degradation in SC-NCM, highlighting interfacial chemistry regulation as an effective strategy for stabilizing SC-NCM under high-voltage operation.

Ni loading governs the structure and electronic properties of NiMoWS phases. • Moderate Ni promotes an optimal -SH/CUS balance at Mo(W) edges. • Excess Ni disrupts -SH/CUS matching, suppressing hydrodesulfurization activity. Stringent environmental regulations and the need to process heavy, sour crudes are driving the development of advanced hydrodesulfurization (HDS) catalysts, particularly Ni-promoted Mo/W sulfide catalysts. Although the promotional role of Ni in sulfide HDS catalysts is well recognized, the origin of activity suppression under Ni-rich conditions remains unclear. In this work, a series of high-loading NiMoW/SiO 2 catalysts with varying Ni contents were investigated to clarify why further Ni addition leads to activity suppression in the HDS reaction under Ni-rich conditions. Combined Py-IR, EPR, Raman, XPS, and DFT analysis reveal that the key factor is the balance between -SH and coordinatively unsaturated sites (CUS) on the sulfide surface. An appropriate Ni content increases the abundance of catalytically effective sites while maintaining favorable -SH/CUS matching, leading to the highest HDS activity for Ni 1 Mo 1 W 1 . In contrast, excess Ni causes a continuous increase in the relative abundance of -SH species without a corresponding effective generation of additional CUS sites, thereby disrupting the -SH/CUS balance and suppressing DBT conversion. The optimized Ni 1 Mo 1 W 1 catalyst also exhibited stable performance over five cycles and a 1.47-fold higher relative volume activity than the industrial NiMo/γ-Al 2 O 3 reference catalyst (8 MPa, 300 °C), and good stability during a 360 h real-oil hydrotreating test. This work identifies -SH/CUS imbalance as a major origin of activity suppression under Ni-rich conditions in NiMoW catalysts.

Ni/Rh nanoalloy matches the rates of two sub-reactions for urea electrosynthesis. • Rh-driven *CO dispatching redirects the reaction pathway from CO to urea. • Comprehensive in situ ATR-SEIRAS elucidates the distinct roles of Ni and Rh. • The FE Urea /FE CO for Ni/Rh nanoalloy boosts 30 times than that of Ni-BNC. The electrocatalytic co-reduction of CO 2 and nitrate (NO 3 - ) presents a sustainable route for urea synthesis, yet it is severely hampered by mismatched activation rates of the two sub-reactions (CO 2 reduction reaction and nitrate reduction reaction). Herein, building on our previous study of Ni-BNC for CO 2 to CO conversion, we constructed a Ni/Rh nanoalloy catalyst (Ni/Rh-BNC) via Rh-incorporation strategy to effectively redirect reaction pathway to urea from CO. Systematic in situ ATR-SEIRAS and Raman spectroscopy provide mechanistic insights into the intermediate evolution and reaction pathway switching. While Ni acts as a *CO generator, the incorporated Rh species serves a triple regulatory role: (i) activating NO 3 - to balance the two sub-reaction rates; (ii) stabilizing *CO intermediates generated from adjacent Ni sites via *CO transfer; and (iii) directly initiating C-N coupling to form urea. This Rh-driven *CO “dispatching” mechanism suppresses CO desorption and steers the pathway toward urea formation. Consequently, the urea-to-CO Faradaic efficiency (FE) ratio for Ni/Rh-BNC boosts nearly 30 times than that of Ni-BNC, achieving a urea FE of 31.2% at −0.7 V vs. RHE, with a maximum urea yield of 7981.8 mg·g metal −1 ·h −1 under low metal loading conditions. This strategy underscores a promising blueprint for rational catalyst design of dual metal sites enabling reaction pathway redirection and sub-reaction rate matching for multi-step electrocatalytic reactions.

In order to get a filter with oxidation resistance at high temperature, Ni–Cr alloy foam was prepared by vacuum evaporation deposition chromium on pure nickel foam. The effects of evaporation temperature and evaporation time on the Cr content, microstructure, compressive property and oxidation performance of the Ni–Cr alloy foams were investigated. The Ni–Cr alloy foam has a filament diameter of approximately 60–130 μm and a pore size of 200–330 μm, respectively. The results showed that increasing evaporation temperature and extending evaporation time can significantly increase Cr deposition and improve the uniformity of element distribution. The Ni–Cr alloy foam prepared by evaporation at 1100 ℃ for 1 h has a Cr content about 22.9 wt%, and its compressive strength reached 5.5 MPa at a strain of 0.35 while no fracture occurred. The Ni–Cr alloy foam has oxidation rates of 71.6, 79.2 and 171.0 mg/(m 2 ·h) at 600 °C, 700 °C and 800 °C, respectively, showing a good oxidation resistance. Therefore, vacuum evaporation deposition can realize alloying of pure nickel foam with chromium to get Ni–Cr alloy foam, with the characteristics of simple process, controllable composition and good properties.

The intrinsic activity-stability trade-off remains a fundamental constraint for metal oxide catalysts in propane dehydrogenation (PDH). Herein, we break this limitation via a well-defined dual-site catalyst comprising ZnO clusters and adjacent Ni single atoms on γ-Al2O3, constructed through a metal-doped carbon dot precursor strategy. This configuration achieves a 5-fold and 2-fold enhancement in propylene formation rate compared to the sole Ni and ZnO catalysts, respectively, while maintaining high propylene selectivity (>93%) and long-term stability over 100 h. Combined kinetic and in situ spectroscopic studies establish a cooperative mechanism wherein under-coordinated Zn2+ sites serve as the primary centers for C−H activation, while neighboring (Ni−)O sites function as dynamic regulators of interfacial hydrogen transfer. Direct evidence from temperature-programmed D2 adsorption and time-resolved propane DRIFTS reveals that the hydrogen transfer rate scales linearly with Ni loading, correlating inversely with the apparent activation energy for dehydrogenation. This (Ni−)O-mediated process dynamically reduces surface hydrogen coverage on ZnO, lowers the energy barrier for C−H cleavage, and concurrently suppresses C−C cracking pathways. This work establishes a design paradigm of using atomically dispersed metals as kinetic regulators of surface hydrogen dynamics, shifting the promoter role from static modifier to active mediator of surface pathways, offering a general strategy for advanced metal oxide catalyst design in alkane dehydrogenation.

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.
