Metal-organic frameworks (MOFs) have ordered porous structure and intriguing properties for supercapacitors , however, poor conductivity and cycle stability limits their application. To solve these problems, hence, a simple strategy is proposed, by which MOFs are in-situ grown in the porous conductive p-MXene substrate. And then, along with the introduction of CuS, the grown Ni-MOF is derived to Ni 3 S 4 , which is more stable and more electrochemically active. Due to higher contact area, excellent synergistic effect and more exposed active sites, the prepared sandwiched p-MXene@Ni 3 S 4 /CuS nanostructure displays a big specific capacitance (1917 F·g −1 ) and superior cycling performance (91.2%@30000). What’s more, the assembled p-MXene@Ni 3 S 4 /CuS//AC asymmetric device delivers a high energy density of 87.62 Wh·Kg −1 at the power density of 775.02 W·Kg −1 , suggesting that this material provides a brilliant candidate for energy storage.

The optimal hydrogen evolution for composite materials NiMnO 3 /Ni 3 S 4 is 3.76 μmol mg −1 h −1 , that 3.7 and 4 times more than that of two monomer materials, respectively. After four cycles of catalytic experiments, proving the high efficiency and stability of the composite catalyst. The characteristics of fluorescence spectroscopy and electrochemistry have confirmed the existence of p-n heterostructures , the excellent catalytic performance is related to the built-in electric field (accelerating the separation and utilization of photocharges) generated by the combination of NiMnO 3 and Ni 3 S 4 .

Ni 3 S 4 /NiS 2 composite powder with controllable morphology and proportion is synthesized without using any surfactant in choline chloride-ethylene glycol (ChCl-EG) deep eutectic solvent (DES) at 120 °C. The products are characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) to reveal the effects of reaction time, and reactant concentration on their composition and structure. The reaction mechanism for synthesizing Ni 3 S 4 /NiS 2 in ChCl-EG DES is also elaborated. The results show that different proportions of wrinkled, lamellar and layer-rolled Ni 3 S 4 /NiS 2 can be obtained by controlling the concentration of NiCl 2 ·6H 2 O and Na 2 S 2 O 3 ·5H 2 O. The analysis found that the reaction mechanism of Ni 3 S 4 /NiS 2 is Ni(II) reacting with S 2 O 3 2− and H 2 O to form Ni 3 S 4 , NiS 2 , SO 4 2− , and H + . The NMR hydrogen spectrum ( 1 H NMR), NMR carbon spectrum ( 13 C NMR) and FT-IR tests of ChCl-EG indicate that it is structurally stable, and acted as a solvent and template during the reaction process.

The objective of this work was to prepare and evaluate Ni 3 S 4 /graphene nanostructures for making high-performance supercapacitor electrodes. A one-pot solvothermal method was developed to prepare the hierarchical nanostructures consisting of Ni 3 S 4 nanoflowers on graphene nanosheets. Due to the hierarchical structure of Ni 3 S 4 nanoflowers on graphene nanosheets, the resulting electrodes exhibited high supercapacitive performance. Herein, the Ni 3 S 4 /graphene electrode demonstrated the specific capacitance of 978.4 F g –1 at the current density of 0.5 A g –1 , the rate capability and long-term cycling stability were also excellent. Moreover, the capacitance contribution of NG-60 can reach 87.9% of the total capacity at 10 mV s −1 . The high pseudo-capacitive performance can be attributed to the superior electronic conductivity of graphene nanosheets and the well interconnected tiny pores/channels in the Ni 3 S 4 nanoflower arrays. The prepared Ni 3 S 4 /graphene hierarchical nanostructures may be promising as innovative electrode materials for making high-performance supercapacitors.

The development of sodium-ion batteries with a high-power density and long life has attracted considerable interest because of their low cost and potential applications. In this work, we constructed N-doped graphene supported pseudocapacitive material consisting of Ni 3 S 4 grains (50 nm) coated by 3–4 layers of MoS 2 (MoS 2 @Ni 3 S 4 /NG) by facile one-step pyrolysis of nickel phthalocyanine. When the electrode was used as an anode for sodium-ion batteries, a pseudocapacitance-dominated storage mechanism was established, and the extrinsic pseudocapacitance could be further enhanced with the structural evolution of MoS 2 @Ni 3 S 4 during the sodiation/desodiation process, contributing to fast kinetics of Na + storage. The results of impedance analysis indicated that the MoS 2 layers play a vital role in reducing the charge-transfer resistance because the MoS 2 with wider interlayer spacing enables Na + to intercalate with a lower energy barrier compared with intercalating into Ni 3 S 4 directly. As a result, the electrode exhibits a superior cycle life over 1000 cycles, and an excellent rate capacity of 564 mAh g −1 can be achieved at 0.5 A g −1 .

A novel ternary photocatalyst Ni 3 S 4 @ZIS@C 3 N 5 with type II and Z-type heterojunctions was synthesized for the first time by hydrothermal and electrostatic self-assembly methods, effectively avoiding the thermal decomposition of C 3 N 5 during the synthesis of the complex. The best ternary catalyst Ni 3 S 4 @ZIS@C 3 N 5 is capable of achieving an optimal hydrogen evolution rate of 9750 mmol g −1 h −1 , which is approximately 10.89 times as high as that of C 3 N 5 , indicating that the complex effectively enhanced the photocatalytic properties of the monomer . The coexistence of two types of heterojunctions in the complex effectively enhances photocatalytic performance, in which the monomer ZIS constructs type II scheme with Ni 3 S 4 and Z-type scheme with C 3 N 5 , respectively. The two heterojunctions complement each other and jointly promote the rapid electron transfer from Ni 3 S 4 and C 3 N 5 to the ZIS surface. In conclusion, the cooperation of the two heterojunctions efficiently facilitates the migration of photogenerated carriers, thus enhancing the photocatalytic hydrogen generation performance of Ni 3 S 4 @ZIS@C 3 N 5 .

MnCo 2 O 4 is regarded as a good electrode material for supercapacitor due to its high specific capacity and good structural stability . However, its poor electrical conductivity limits its wide-range applications. To solve this issue, we integrated the MnCo 2 O 4 with Ni 3 S 4 , which has a good electrical conductivity, and synthesized a MnCo 2 O 4 /Ni 3 S 4 nanocomposite using a two-step hydrothermal process. Comparing with individual MnCo 2 O 4 and Ni 3 S 4 , the MnCo 2 O 4 /Ni 3 S 4 nanocomposite showed a higher specific capacity and a better cycling stability as the electrode for the supercapacitor. The specific capacity value of the MnCo 2 O 4 /Ni 3 S 4 electrode was 904.7 C g −1 at 1 A g −1 with a potential window of 0–0.55 V. A hybrid supercapacitor (HSC), assembled using MnCo 2 O 4 /Ni 3 S 4 and active carbon as the cathode and anode, respectively, showed a capacitance of 116.4 F g −1 at 1 A g −1 , and a high energy density of 50.7 Wh kg −1 at 405.8 W kg −1 . Long-term electrochemical stability tests showed an obvious increase of the HSC’s capacitance after 5500 charge/discharge cycles, reached a maximum value of ∼162.7% of its initial value after 25,000 cycles, and then remained a stable value up to 64,000 cycles. Simultaneously, its energy density was increased to 54.2 Wh kg −1 at 380.3 W kg −1 after 64,000 cycles.

Yolk-shell structure materials with the light weight, excellent impedance matching and electromagnetic wave (EMW) loss ability were widely used in the field of absorbing materials. However, the previous researches on this kind of structure always focused on the comparison between solid structure and empty structure. Different from previous studies, in this paper, the effect of yolk-shell structure with different air layer thickness on EMW absorption was studied for the first time. Graphene oxide (GO) supported yolk-shell ZnS/Ni 3 S 4 absorbers with adjustable air layer were prepared by a simple two-step hydrothermal method. Through the equivalence of RLC resonant circuit and the elimination of the influence of polarization relaxation and conduction loss, it was found that yolk-shell structure with different air layer thickness will resonate with EMW of different frequencies, thus increasing the loss capacity of materials to EMW of this frequency. At the same time, Compared with the solid structure, the yolk-shell structure can not only make the material lighter, but also cause multiple reflections and scattering of EMW. Noteworthy, yolk-shell structure composite material exhibits the maximum reflection loss (RL) of −63.0 dB at 4.8 GHz and an effective absorption bandwidth (EAB) of 4.1 GHz at a thickness of 1.6 mm. This research provides an idea and basis for the design of absorbing materials that respond to different frequency EMW.

The oxidative degradation of plastics in conjunction with the production of clean hydrogen (H 2 ) represents a significant challenge. Herein, a Ni 3 S 4 /ZnCdS heterojunction is rationally synthesized and employed for the efficient production of H 2 and high-selectivity value-added chemicals from waste plastic. By integrating spectroscopic analysis techniques with density functional theory (DFT) calculations, a solely electron transfer-mediated reaction mechanism is confirmed, wherein Ni 3 S 4 extracts electrons from ZnCdS (ZCS) to promote the spatial segregation of photogenerated electrons and holes, which not only facilitates H 2 production but also maintains the high oxidation potential of holes on the ZCS surface, favoring hole-dominated plastic oxidation. Notably, the catalyst exhibited efficient H 2 production rates as high as 27.9 and 17.4 mmol g −1 h −1 , along with a selectivity of 94.2% and 78.3% in the liquid product toward pyruvate and acetate production from polylactic acid (PLA) and polyethylene terephthalate (PET), respectively. Additionally, carbon yields of 26.5% for pyruvate and 2.2% for acetate are measured after 9 h of photoreforming, representing the highest values reported to date. Overall, this research presents a promising approach for converting plastic waste into H 2 fuel and high-selectivity valuable chemical products, offering a potential solution to the growing issue of “ White Pollution ”.
