Biocarbon-supported polymetallic composites (CAS@Ni 3 S 4 /CeO 2 ) were fabricated by a facile hydrothermal process. The as-prepared CAS@Ni 3 S 4 /CeO 2 materials integrated the advantages of transition metal sulfides (good conductivity), rare-earth metal oxides (excellent stability), as well as porous carbon with high surface area, thus exhibiting promising electrochemical performance in supercapacitor applications. Indeed, the optimal CAS@Ni 3 S 4 /CeO 2 -150 composite displayed a high specific capacitance of 1364 F g −1 and impressive cycle performance with capacitance retention of 93.81 % after 10,000 cycles. The calculation of capacitance contribution showed that the satisfying behavior of the electrode was a combination of the diffusion process and the surface capacitance characteristics. Furthermore, the assembled asymmetric supercapacitor (CAS@Ni 3 S 4 /CeO 2 -150//CAS) delivered an ultrahigh energy density of 102.76 Wh kg −1 , which was better than that of the commercial activated carbon-based ASC device. This novel strategy might provide a new perspective for transition metal sulfide/rare earth metal oxide composite in the electrochemical energy storage field.

Incorporating metal compound nanoparticles into zeolitic imidazolate frameworks (ZIFs) has emerged as an effective way to solve the low conductivity issue of ZIFs, helping to boost their electrochemical performance. However, the resultant ZIFs/metal compound composites usually lack hierarchical pores, which causes the electrochemical performance to be far below expectations. Here, two rational post-treating strategies, namely, Ni2+/H2O etching and solvent-assisted etching, have been proposed to tailor the structure and composition of ZIF-67/Ni3S4 composite. Especially, Ni2+/H2O etching enables the self-transformation of ZIF-67 to CoNi layered double hydroxide (LDH), while solvent-assisted etching creates hierarchical pores in ZIF-67. After post-treatments, both resultant samples display significant improvements in energy storage capability and cycling lifespan as compared to untreated ZIF-67/Ni3S4 owing to their superior features including the hierarchical pore structure, enhanced pseudocapacitance property, and less internal and charge transfer resistance. The tailoring strategies together with mechanism studied here can provide perspectives and constructive designing knowledge to promote the widespread use of ZIFs or Ni3S4 based advanced electrodes toward high-performance supercapacitors.

Ni 3 S 4 @MoS 2 nanosheets grown on the carbon fiber paper (Ni 3 S 4 @MoS 2 /CFP) were successfully prepared via a facile one-step hydrothermal technique. Serving as a supercapacitor electrode, the obtaining Ni 3 S 4 @MoS 2 /CFP exhibits a remarkable specific capacitance of 1296 F/g, high rate capability of 57.8%, and excellent cycling stability of 96.2% retention after 5000 cycles. The superior electrochemical properties of Ni 3 S 4 @MoS 2 /CFP nanocomposite is attributed to the synergistic effects of the layeredNi 3 S 4 , MoS 2 and the conductive CFP.

Nickel sulfide possesses ultra-high theoretical energy storage capacity. Though it is easily obtained, it is very difficult to exert its intrinsic strong capacity. In this work, a new strategy based on a binary synergy of sulfur sources is introduced. By regulating the molar ratio of two sulfur sources, a high-performance α-NiS/Ni 3 S 4 binary hybrid is successfully synthesized. Interestingly, it is found that changing the molar ratio of two sulfur sources in hydrothermal process can efficiently regulate the components of product but cannot visibly affect its morphology. The electrochemical results indicate that this strategy is highly effective for improving the performance of nickel sulfide. As a result, a highest specific capacity of 214.9 mAh g −1 at 2 A g −1 was reached. In addition, the fabricated S3//rGO hybrid supercapacitor displays a highest energy density of 41.9 Wh kg −1 at a power density of 799.0 kW kg −1 . Moreover, the device delivers an excellent cycle stability with 103% capacity retention rate after 10,000 cycles. These findings open a new avenue for the controlled synthesis of high-performance nickel sulfides or other metal sulfides.

With ammonia playing a more and more vital role in serving as a renewable hydrogen carrier, it is critical to develop economical and efficient electrocatalysts for the ammonia oxidation reaction (AOR) in which hydrogen is released. In this work, a heterostructured electrocatalyst, Ni 3 S 4 @NiCo 2 O 4 /NF, was synthesized using the hydrothermal method for the purpose of improving AOR efficiency. The obtained nano catalyst exhibited an excellent AOR activity (10 mA·cm −2 at 0.58 V vs. Hg/HgO) and stability (37.2 h at 100 mA·cm −2 ). XRD and XPS characterizations indicated that the bulk catalyst remained unchanged yet with surface metallic Ni oxidized. In situ Raman spectroscopy analysis further revealed that the heterostructured catalyst underwent an obvious surface reconstruction process (Ni(OH) 2 → β-NiOOH → γ-NiOOH) which accordingly lowered the potential required for reconstruction and optimized the energy barrier for the AOR. DFT calculations showed that the heterostructured catalyst not only favors the acceleration of the reconstruction process due to electronic interactions, but also reduces the energy barrier in *NHNH 2 generation step, thus enhancing the performance of AOR, which is superior to the other two catalysts. The product gas analysis showed that the developed catalyst maintained an excellent Faraday efficiency of 95% and a continued activity. In summary, this work opened a potential new pathway for the design of heterostructured electrocatalysts for H 2 production through AOR.

Graphical A facile approach has been developed to prepare a NiFe 2 O 4 /Ni 3 S 4 heterostructure. The NiFe 2 O 4 /Ni 3 S 4 catalyst exhibited superior performance toward oxygen evolution reaction and Zn-air batteries than IrO 2 . The excellent performance is mainly attributed to the structural merits of the two components, the abundant oxygen vacancies in the catalyst, and the boosted synergistic catalytic effects occurring at the heterostructure interface. Developing high-performance catalysts for oxygen evolution reaction (OER) is critical for the widespread applications of clean and sustainable energy through electrochemical devices such as zinc-air batteries and (photo)electrochemical water splitting. Constructing heterostructure and oxygen vacancies have demonstrated great promises to boost the OER performance. Herein, we report a facile strategy to fabricate hetero-structured NiFe 2 O 4 /Ni 3 S 4 nanorods, where NiFe 2 O 4 can be derived from Fe-based metal-organic frameworks (MOFs). The NiFe 2 O 4 /Ni 3 S 4 catalyst exhibited excellent OER performance, evidenced by an overpotential value of 357 mV at the current density of 20 mA cm −2 , and a small Tafel slope of 87.46 mV dec −1 in 1 M KOH, superior to the benchmark IrO 2 catalyst. Moreover, NiFe 2 O 4 /Ni 3 S 4 outperformed with regard to long-term durability for OER than IrO 2 . Such outstanding OER performance is mainly accounted by the interface between NiFe 2 O 4 and Ni 3 S 4 , and the presence of rich oxygen vacancies. When employed as air-cathode in zinc-air batteries, the NiFe 2 O 4 /Ni 3 S 4 decorated battery had a high round-trip efficiency of 62.1% at 10 h, and possessed long-term stability of >50 h. This study may pave the way for fabricating non-noble-metal-based cost-effective, efficient and durable electrocatalysts for OER, zinc-air batteries, and beyond.

Nickel sulfides have been considered to be among the most effective oxygen evolution reaction (OER) electrocatalysts . Until now, there are many different nickel sulfides, such as Ni 3 S 2 , NiS, Ni 3 S 4 , NiS 2 , etc. In this paper, we set out to explore the influence of the S:Ni ratio in raw materials on the different nickel sulfides. With the characterizations of XRD , XPS , SEM, TEM and BET, the relevance between the molar ratio of S:Ni in raw materials and stoichiometric ratio, microscopic structure and OER performance are discussed. According to the results of the experiments, the Ni 3 S 4 derived from the 3:1 M ratio of S:Ni in raw material exhibits the smallest overpotential (245 and 314 mV to achieve 10 and 20 mA/cm 2 ) and Tafel slope (81.5 mV/dec). Meanwhile, theoretical calculation of ΔG(H 2 O*) indicate that the adsorption energy in Ni 3 S 4 is much closer to the IrO 2 than other nickel sulfides, which are in good agreement with the OER performance of electrochemical measurements.

Dielectric constant modulation and
heterointerface engineering
are considered efficacious strategies to construct high-performance
electromagnetic wave (EMW) absorption. Herein, a series of dual-phase
nickel sulfide (NiS 2 /Ni 3 S 4 ) hierarchical
microspheres decorated with diverse contents of silicon dioxide (SiO 2 ) nanospheres have been successfully synthesized via the Stöber
method and subsequent solvothermal process. Profiting from the rational
dielectric constant regulation, the NiS 2 /Ni 3 S 4 /SiO 2 -1 composites achieve an optimal RL
value of −66.6 dB at 2.09 mm and the broadest effective absorption
bandwidth (EAB) of 6.28 GHz at 2.18 mm within a filler loading of
20 wt %, far superior to that of pure NiS 2 /Ni 3 S 4 composites. When the content of absorber increases
to 25 wt %, the microwave absorption properties of NiS 2 /Ni 3 S 4 /SiO 2 -1 composites are the
utmost, further verifying the importance of a reasonable addition
amount of SiO 2 nanospheres. It is concluded that the introduction
of SiO 2 nanospheres can not only expand the heterogeneous
interface but also improve impedance matching by regulating the dielectric
constant. Furthermore, the results of radar cross section (RCS) simulation
demonstrate the dissipative capability for radar signals in practical
applications. The findings furnish a viable pathway for exploring
broadband microwave-absorbing materials.

The hydrogen evolution reaction (HER) in alkaline media is a promising strategy for sustainable hydrogen production, but the exploration of efficient and durable HER electrocatalysts is often hindered by the empirical and time-consuming nature of traditional synthesis. Herein, a machine learning (ML)–driven strategy combining Bayesian optimization is introduced to achieve the rational design of Ni 3 S 4 /Ni 3 Mo heterostructures for alkaline HER. By coupling predictive modeling with experimental feedback, this approach efficiently navigated a complex synthesis space and identified conditions yielding a structurally and electronically optimized catalyst. The optimized Ni 3 S 4 /Ni 3 Mo exhibits a vibrant morphological evolution—from compact buds to blooming petal-like structures—enabling enriched active sites and accelerated mass transport. Guided by Bayesian optimization, the optimized Ni 3 S 4 /Ni 3 Mo achieves a 10.5-fold enhancement in C dl and delivers an exceptionally low overpotential of 18.2 mV at 100 mA cm −2 , outperforming most reported transition-metal catalysts and even surpassing commercial Pt/C. Mechanistic insights from in situ Raman and DFT reveal that interfacial charge redistribution between Ni 3 S 4 and Ni 3 Mo optimizes H* adsorption (Δ G H* ≈ 0.04 eV) and significantly reduces the water-dissociation barrier (0.08 eV), thereby accelerating reaction kinetics. This work demonstrates how the ML-guided optimization can synergistically couple morphology control, interfacial engineering with electronic tuning, offering a generalizable framework for intelligent catalyst discovery and mechanistic understanding in electrochemical energy conversion.

In this work, a two-step protocol was proposed to prepare NiS/Ni 3 S 4 composite nanosheets as an electrode material for supercapacitors. The composite nanosheets were prepared by hydrothermal sulfuration on the α-Ni(OH) 2 monolayer nanosheets that were produced by grinding the mixture of nickel salt and morpholine at room temperature. The results of morphology observation indicated that the composite prepared at 140 °C had sheet-like morphology and large lateral size. It presented high-specific capacitance (2070.0 F g −1 at current density of 2.5 A g −1 ) and excellent electrochemical stability (86% retention of initial capacitance after 10,000 charge–discharge cycles). It was considered that the high electrochemical performance of this composite could be attributed to its sheet-like morphology and the introduction of Ni 3 S 4 phase.

Herein, coralloid core-shell structure NiS/Ni 3 S 4 @PPy@MoS 2 nanowires were elaborately designed and successfully synthesized through a three-step route to obtain exceptional microwave absorption (MA) properties. Ni nanowires were first fabricated, and then used as the substrate to be coated with a layer of PPy . Ni chalcogenides were obtained by using Ni nanowire as sacrificial templates while growing MoS 2 nanorods by hydrothermal method . Both the one-dimensional (1D) core-shell structure and the coralloid surface generated by MoS 2 nanorods were beneficial for the attenuation of microwaves. After investigating the electromagnetic properties of different loading content absorbers (30 wt.%, 40 wt.% and 50 wt.%), it is found that the 50 wt.% loading absorber has the optimal MA performance. The minimum reflection loss (RL min ) value can reach −51.29 dB at 10.1 GHz with a thickness of 2.29 mm, and the corresponding effective absorption bandwidth (EAB, RL < −10 dB) can be up to 3.24 GHz. This research provides a reference for exploiting novel high-efficient 1D absorbers in the field of MA.

Ni 3 S 4 -based materials are promising candidates for anodes of lithium-ion batteries (LIBs) due to their high theoretical capacities and excellent redox reversibilities. However, the drawbacks, including low intrinsic conductivity, significant volumetric expansion, and polysulfide shuttle effects, hinder their electrochemical performance and limit practical applications. To address these challenges, herein, a ternary fibrous TiO 2 -Ni 3 S 4 -carbon composite using natural cellulose substance as both the carbon source and structural scaffold was synthesized via hydrothermal and sol–gel approaches. The composite exhibits a nanoarchitecture structure, which retains the three-dimensional network structure of the initial cellulose substance; it is composed of uniformly distributed Ni 3 S 4 nanoparticles wrapping around the carbon fibers with the TiO 2 nanoplates coating on the outermost surface. Due to the spatially organized TiO 2 /Ni 3 S 4 /carbon ternary configuration, the composite exhibits excellent electrochemical performance when employed as an anodic material for LIBs. Specifically, the TiO 2 coating layer acts as a protective layer, suppressing the shuttle effect of polysulfides and stabilizing the solid electrolyte interface (SEI). The synergistic effect of the carbon fiber and the TiO 2 coating layer buffers the volume expansion, prevents the pulverization of the active material, and enhances its structural integrity and stability. Additionally, the Ni 3 S 4 -TiO 2 heterojunction accelerates charge transfer and increases the pseudocapacitive contributions, thereby improving lithium storage performance. Specifically, the TiO 2 -Ni 3 S 4 -carbon anode delivers a reversible discharge capacity of 600.2 mAh g –1 at 1.0 A g –1 after 3000 cycles (70.3% retention). In the full-cell tests, the anode achieves a reversible capacity of 107.4 mAh g –1 after 3000 cycles at 1.0 A g –1 with an energy density of 224.3 Wh kg –1 , demonstrating the application potential of the composite as the anodic material of LIBs.
