The paradigm shift toward the disposal of retired batteries demands sustainable and cost-effective recycling methods that surpass conventional pyro-/hydrometallurgy-based techniques, offering superior profitability, energy efficiency, resource utilization, and environmental benefits. In this study, a one-step modulation approach is presented for regenerating spent Ni-rich layered oxides featured with exceptional ion diffusivity and high-temperature stability. By exploiting decomposed species from Li 6 Zr 2 O 7 , monitored via high-temperature X-ray diffraction, the strategy simultaneously enables: Li source replenishment, Zr doping into the bulk lattice, and Conformal ion-conductive Li 2 ZrO 3 coating on regenerated LiNi 0.8 Co 0.1 Mn 0.1 O 2 (R-NCM811-2%LZO). Crucially, the upcycling process strategically utilizes lattice vacancies in the oxide to facilitate Zr dopant diffusion, while Li 2 ZrO 3 coating elevates corrosion resistance and thermal stability. Operando phase tracking reveals that the regenerated cathode maintains reversible lattice breathing and undergoes a continuous, kinetics-boosted phase transition. By pairing R-NCM811-2%LZO cathode with graphite anode in a 3.0 Ah pouch-format cell, the prototype achieves an energy density of 302 Wh kg −1 , extreme power output of 1260 W kg −1 , 63% mitigation of self-discharge rate at 55 °C, as well as robust cycling across a wide temperature range. This value-added strategy upgrades spent NCM811 into high-temperature-tolerant, fast-charging cathodes, paving the way for sustainable battery recycling and circular economy initiatives.

This work proposes a facile route to fabricate Ni/SiO2 nanocomposite catalysts for dry reforming of methane, in which the hydrolysis and condensation of tetraethyl orthosilicate starts and then proceeds around the in situ-formed nickel hydroxide colloids that are stabilized by cetyltrimethylammonium bromide during precipitation using ammonium hydroxide. The average size of Ni nanoparticles (NPs) embedded in a macroporous silica matrix monotonically increases as the initial Ni2+ concentration increases from 0.05 to 0.2 M in the precipitation step, and it is around 6 nm when the latter is 0.2 M. At 750 °C and 1 atm, the reverse water gas shift reaction appears to be more important on small Ni particles than on large ones, and reforming stability over large particles (6 nm) is higher than that of small ones (4 and 4.9 nm). The reforming catalyst with the largest Ni NPs exhibits excellent stability at a weight hourly space velocity of 60 L gcat–1 h–1: methane conversion maintains at ∼88% and H2/CO molar ratio marginally fluctuates around 0.97 during the 100 h of continuous operation. After the stability test, the size of Ni NPs slightly increases but the pattern of spatial confinement remains intact. Moreover, the amount of catalytic coke in the spent catalyst is around 0.18 wt %. However, no carbonaceous materials are detected in the spent one by X-ray diffraction, Raman spectroscopy, and transmission electron microscopy. Thus, the proposed method may be used to prepare other nickel-based catalysts for hydrocarbon catalytic transformations involving sintering and/or coking.

Crack-free Ni-rich single-crystal cathodes exhibit exceptional stability; however, they encounter challenges pertaining to kinetic hindrance, low capacity, and low initial Coulombic efficiency. Herein, we present a melt infiltration-dispersion method for synthesizing a small-sized single-crystal LiNi0.90Co0.06Mn0.04O2 (N90-SC) material at lower temperatures, enabling kilogram-scale production. The inclusion of low-melting LiOH-Li2SO4 eutectic salt enhances uniform mass and heat transfer while penetrating the grain boundaries of secondary particles, thereby inhibiting particle growth and resulting in small single crystals after washing. The elevated lithium potential effectively minimizes Li+/Ni2+ disorder and facilitates the doping of a small amount of Li ions into the transition metal layers. Under a high state of charge, Ni ions migrate and occupy the lithium layer, resulting in the formation of a localized superlattice structure. This dynamic superlattice exerts a stabilizing pillar effect through robust Ni interlayer superexchange interactions, thus reinforcing the deintercalated structure and promoting a reversible H2–H3 phase transition. At the end of discharge, lithium doping reduces the lithium diffusion barrier by mitigating the electrostatic repulsion effect, enhancing the lithium diffusion coefficient and alleviating the kinetic hindrance of Ni-rich single-crystal cathodes. Consequently, the N90-SC material achieves a high capacity of 227.7 mAh g–1 and an impressive initial Coulombic efficiency of 94.8%. The pouch-type N90-SC||Graphite full cell demonstrates an ultrahigh initial Coulombic efficiency of 93.3% and maintains 88.2% capacity after 500 cycles. This work offers a dual-benefit strategy that concurrently addresses kinetic hindrance and structural stability, while localized atomic-scale engineering provides further insights into the design of next-generation lithium-ion batteries.

L-Cysteine (L-Cys), a sulfur-containing amino acid, plays a crucial role in various biological processes. Rapid and accurate detection of L-Cys in the human body is significant for clinical diagnosis and drug analysis. However, classic electrochemical sensing mechanisms are usually based on redox reactions, and substances with similar redox properties in the serum can easily interfere with the detection process. In this study, we present a novel approach for the detection of L-Cys using Schottky barriers of Ni/Cu2O/Ag nanocubes. The electrode exhibits excellent selectivity towards L-Cys due to the specific interaction between Cu2O and L-Cys through the formation of Cu–S bonds. The Schottky barrier at the Cu2O/Ag interface, formed due to the difference in work functions, impedes electron transfer and can be modulated by the adsorption of charged L-Cys molecules. The introduction of light irradiation enhances the barrier modulation capability, resulting in improved sensitivity. Experimental results demonstrate that the Ni/Cu2O/Ag electrode exhibits a linear response to L-Cys concentration within 0–2400 nM at pH 3.0 and pH 7.0, with a low detection limit of 11.86 nM. The electrode shows excellent performance in real sample analysis, exhibiting high recovery rates and low relative standard deviations. The light-assisted barrier enhancement mechanism provides a new avenue for the development of highly selective and sensitive electrochemical sensors.

The development of efficient and durable non-precious metal catalysts for hydrogen evolution reaction (HER) remains a significant challenge. In this work, we present a novel approach combining heterojunction and structural engineering to enhance HER performance. A NiO/Ni layer with a heterogeneous structure is grown on CuO nanorod arrays supported by copper foam. This 3D nanostructure increases the density of active sites, improves mass and electron transport, and accelerates HER kinetics. The rough surface also facilitates rapid bubble release, enhancing catalyst stability under high currents. As a result, the CuO@NiO/Ni catalyst exhibits excellent HER performance, with overpotentials of 86.5 and 198.8 mV at 100 and 500 mA cm −2 , respectively. Additionally, a two-electrode electrolytic cell using CuO@NiO/Ni and NiFe LDH achieves 500 mA cm −2 at only 1.64 V and maintains excellent stability over 100 h. These findings highlight the potential of CuO@NiO/Ni as a highly efficient, stable catalyst for industrial-scale water electrolysis, and provide a promising approach to addressing the challenges of non-precious metal-based HER catalysts in industrial settings.

The electrochemical conversion of glycerol into dihydroxyacetone (DHA) under mild conditions efficiently addresses glycerol surplus, enhancing its economic value. However, DHA production efficiency remains constrained by steric hindrance from secondary hydroxyl groups and sluggish glycerol electro-oxidation reaction (GOR) kinetics in weakly alkaline conditions. Herein, lignin-derived carbon-supported MnO–Ni heterojunction catalyst (MnO–Ni/C) is synthesized via self-assembly precipitation and in situ pyrolysis. The optimized MnO–Ni/C catalyst requires a low potential of 1.58 V to achieve 10 mA cm −2 , 270 mV lower than the oxygen evolution reaction (OER). It attains a 53.37% DHA selectivity with a high production rate of 864.75 mmol m −2 h −1 at 1.8 V. MnO–Ni/C heterostructures modulate the local electronic structure of Ni sites, optimizing glycerol adsorption configuration and enhancing selective adsorption of secondary hydroxyl groups and oxygen active species near the electrode surface. These synergistic effects significantly improve GOR kinetics and DHA production efficiency.

At present, most of the catalysts used for heterogeneous hydrogenation of nitrile butadiene rubber (NBR) are noble metal catalysts, which require high metal loading but low metal utilization and face challenges in recovery, leading to significant resource waste. The steric hindrance imposed by the large polymer molecules renders the hydrogenation of unsaturated C═C bonds in the backbone particularly challenging, and the degree of hydrogenation is low. In this experiment, Pd–Ni bimetallic nanocatalyst was prepared by co-impregnation method. The catalyst has uniformly distributed catalytic site and high selectivity for C═C bond hydrogenation and achieved a hydrogenation degree of 96% under optimized reaction conditions. The electronic state of Pd is modulated by Ni, enhancing hydrogen activation and catalytic activity. This study provides a novel strategy for developing NBR hydrogenation catalysts, which is significant for the large-scale production of high-value-added HNBR.

High infrared emissivity coatings have important engineering value in aerospace and electronic devices. In this study, a new method for preparing high infrared emissivity coatings using magnetic field-assisted jet electrodeposition was prepared. The magnetic field-assisted jet electrodeposition technique can be used to prepare coatings with rough structures, and the infrared emissivity of nickel particle coatings can reach 0.80 at a magnetic field intensity of 100 mT, which is significantly improved compared with the nickel coatings (0.155) prepared by conventional electrodeposition. A nickel-based SiC composite coating with high infrared emissivity was prepared by combining magnetic field-assisted jet electrodeposition with SiC particles. Compared with the nickel particle coating, the infrared emissivity of the nickel-based SiC composite coating is further improved. At a concentration of 6 g/L SiC particles, the infrared emissivity of the nickel-based SiC composite coating reached 0.94. The synergistic effect of magnetic field-assisted jet electrodeposition and SiC particles can realize the nickel coatings into coatings with high infrared emissivity.

Ni-based catalysts derived from Ni-Al-Y layered double hydroxides with various amounts of yttrium were synthesized by a condensation reflux method. At the optimized Al/Y atomic ratio of 24/1, the obtained H-Ni 75 Al 24 Y 1 sample showed the highest CO 2 methanation performance. At a WHSV of 15,000 mL h -1 g -1 and a pressure of 0.1 MPa, the CO 2 conversion reached 84.1% with 100% selectivity to CH 4 at 250°C, which was much higher than that of H-Ni 75 Al 25 (75.7%) prepared by the hydrothermal method. Furthermore, the CO 2 conversion over H-Ni 75 Al 24 Y 1 sample rose to 88.7% at 300°C, which exceeded that of the Y-free counterpart (84.1%). The introduction of Y altered the amount and distribution of basic sites as revealed by CO 2 -TPD and led to smaller size and higher dispersion of Ni as proved by XRD, TEM and XPS. The H 2 -TPR result verified stronger metal-support interaction but higher amount of reducible Ni weakly interacted with the support in Ni 75 Al 24 Y 1 LDH sample compared with the Y-free counterpart. As a result, the dissociation of H 2 over Ni sites and subsequent hydrogenation became faster based on the in situ DRIFTS results. Dual pathways were proposed to illustrate the reaction mechanism of CO 2 methanation.

The utilization of industrially generated lignin is an important aspect of achieving worldwide carbon neutrality. In this study, Ni/CaO, Ce/CaO and (Ni-Ce)/CaO catalysts were prepared using an impregnation method to improve the production of H 2 -enriched syngas from lignin steam gasification. Results show that the Ni/CaO and Ce/CaO exhibited different effects when applied to steam gasification, the former improved the conversion of solid lignin whereas the latter promoted decomposition of the resulting volatiles. The (Ni-Ce)/CaO catalyst provided a remarkable synergistic effect on production of H 2 -enriched syngas. The mass-based yield of gaseous products and the volume-based proportion of H 2 in these products were respectively 70.8% and 61.1% in the presence of the (Ni-Ce)/CaO catalyst with a Ni-to-Ce molar ratio of 1:0.9. The H 2 yields obtained from this material were found to gradually decrease from 763 to 681 mL/(g lignin) during five repeated uses. This gradual deactivation of the (Ni-Ce)/CaO catalyst was ascribed to both carbon deposition and the formation of CaSO 4 by reactions between sulfur in the lignin ash and the CaO component.

In this study, a two-phase superhydrophobic nanocomposite coating was prepared by combining electroless deposition and electrodeposition methods. Firstly, the Ni-B /TiC coating were prepared on the metal surface by electroless deposition. Then, the low surface energy cerium myristic acid coatings (Ce [CH 3 (CH 2 ) 12 COO] 3 ) were further prepared on the coating surface by electrodeposition. The test results showed that the two-phase composite coating with Ce [CH 3 (CH 2 ) 12 COO] 3 deposited on the Ni-B/TiC coating (Ni-B/TiC@MACe) had excellent nonwetting properties (water contact angle of 160.1° and rolling angle of 4.3°) and self-cleaning properties. The coating exhibited excellent stability and durability, retaining its superhydrophobicity even after 12 months of exposure to air. Notably, this performance was less affected by pH fluctuations. In addition, mechanical robustness was verified by 50 tape stripping cycles in which the superhydrophobic surface maintained a water contact angle of over 150°. The test results of corrosion resistance showed that the Ni-B/TiC@MACe coating has excellent corrosion resistance with a corrosion inhibition rate of 99.95 %, and the impedance modulus was three orders of magnitude higher than that of the Ni-B coating. In addition, the coating provided protection under simulated acidic conditions with a corrosion potential of - 0.27 V. In a long-term immersion test, the coating impedance modulus remained at 10 6 after seven days of immersion, which effectively protected the underlying metal from corrosion-induced damage. Therefore, the superhydrophobic coating in this study is expected to provide new ideas for the design of new anti-corrosion coatings.

Converting carbon dioxide into fuel via photocatalysis holds immense significance in advancing the cause of sustainable energy generation. In this work, co-doped In 2 O 3 nanosheets with two transition metals, nickel (Ni) and copper (Cu), were successfully prepared using a straightforward ammonia precipitation and calcination technique. Notably, the 10 %Ni-5 %Cu-In 2 O 3 sample exhibited a remarkable CO generation rate of 528.8 μmol g −1 h −1 , which is a substantial 43.63-fold increase compared to the pristine In 2 O 3 (12.1 μmol g −1 h −1 ). Furthermore, the selectivity of the CO product was significantly enhanced from 19.7 % to 69.4 %, marking a significant improvement. The incorporation of Ni and Cu effectively modulated the energy band positions of In 2 O 3 , the synergistic modulation of these bimetals jointly augmented the light absorption of In 2 O 3 across various visible wavelength regions. Additionally, the introduction of Ni and Cu notably prolonged the lifetime of photogenerated carriers and facilitated the spatial separation of electrons and holes. The smaller radius of the doped Ni and Cu ions compared to In may have induced defect formation, leading to a stronger adsorption capacity. Our findings not only underscore the efficacy of transition metal co-doping in photocatalytic CO 2 reduction but also offer valuable insights into the design and fabrication of such catalysts.
