Two-dimensional (2D) layered materials hold great promise for electrochemical energy storage due to their unique structure. It is always desirable to explore new-type high-performance 2D structured electrode materials in energy field. In this work, layered transition-metal chalcogenophosphite is developed as the electrode material for supercapacitors for the first time. NiPS 3 nanosheet arrays are successfully in-situ grown on carbon cloth via a chemical vapor deposition method, and then directly used as the self-supported electrode for supercapacitors. The fabricated carbon cloth supported NiPS 3 nanosheet arrays offer obviously superior electrochemical performance to the powdery NiPS 3 nanosheets sample. The self-supported NiPS 3 electrode exhibits a high specific capacitance of 1148F g −1 at a current density of 1 A g −1 , and a good cycling stability with capacitance retention of 81.4% over 5000 cycles at 10 A g −1 . Moreover, the assembled asymmetric supercapacitor device delivers a specific capacitance of 61.3F g −1 at a current density of 1 A g −1 , and an energy density of 19.2 Wh kg −1 at a power density of 750 W kg −1 with a voltage window of 1.5 V. This work is of great significance for pioneering the application of 2D transition-metal chalcogenophosphites in supercapacitors.

The process of Photocatalytic Hydrogen Evolution (PHE) represents a reliable method for addressing the energy crisis. In this work, a self-assembly method was performed to combine 2D NiPS 3 (NPS) nanosheets (Ns) with 2D CN Ns to prepare NPS Ns/CN Ns (NPCN) 2D/2D heterojunctions with intimately interfacial contact between these two components. Compared to CN Ns, NPCN photocatalysts possess wide-spectrum light absorption regions, excellent light-to-thermal energy effect, electron mobility, charges transfer, and abundant surface active site, thus leading to the enhanced PHE performance for NPCN composites in natural seawater and simulated seawater. Meanwhile, the negative effect of the added various ions on the PHE performance was revealed over 2-NPCN using different typical aqueous solutions. The first-principle calculations and experimental analysis were performed to gain a deep understanding of the underlying mechanisms responsible for the exceptional HER activity over NPCN composites. Drawing from the characterization and DFT calculation results, a photothermal-assisted PHE mechanism was proposed over NPCN composites. This work provides a strategy for the design and synthesis of efficient, stable and highly active g-C 3 N 4 -based heterojunctions.

Developing new electrocatalysts is essentially important for efficient water splitting to produce hydrogen. Two-dimensional (2D) materials provide great potential for high-performance electrocatalysts because of their high specific surface area, abundant active edges, and tunable electronic structure. Here, we report few-layer NiPS3 nanosheet–graphene composites for high-performance electrocatalysts for oxygen evolution reaction (OER). The pure NiPS3 nanosheets show an overpotential of 343 mV for a current density of 10 mA cm–2, which is comparable to that for IrO2 and RuO2 catalysts. More importantly, the NiPS3 nanosheet–graphene composites show significantly improved OER activity due to the synergistic effect. The optimized composite shows a very low overpotential of 294 mV for a current density of 10 mA cm–2, 351 mV for a current density of 100 mA cm–2, a small Tafel slope of 42.6 mV dec–1, and excellent stability. These overall performances are far better than those of the reported 2D materials and even better than those of many traditional materials even at a much lower mass loading of NiPS3.

This study focuses on exploring efficient photocatalysts for water splitting, which holds great potential for harnessing hydrogen (H 2 ) as a renewable energy source. Modulating the heterojunction interface is known to enhance charge carrier separation and solar energy utilization, thereby boosting photocatalytic activity. In this work, a mechanical mixing-assisted self-assembly approach was developed to construct a heterojunction between NiPS 3 (NPS) nanosheets (NSs) and C 3 N 5 (CN) NSs. Specifically, two-dimensional (2D) NPS NSs were tightly deposited on 2D CN NSs surface to gain a 2D/2D heterostructure. The photocatalytic performance of the synthesized photocatalysts was determined by their ability to generate H 2 through water splitting, both in deionized (DI) water and seawater, under visible light. The resulting NPS NSs/CN NSs (NPS/CN) composites possessed boosted photocatalytic hydrogen evolution (PHE) activity related to CN NSs and NPS NSs. This improvement was assigned to the synergistic effect of increased light-harvesting capacity and heterojunction formation. Nevertheless, an excessive amount of deposited NPS NSs on the surface of CN NSs was found to reduce the light absorption of the CN NSs component in the NPS/CN composites, resulting in decreased PHE activity. Therefore, it was determined that an appropriate mass ratio between the two components is necessary to achieve excellent photocatalytic activity for the NPS/CN composites. The optimized photocatalyst, referred to as 3-NPS/CN, demonstrated the highest visible-light-driven PHE efficiency of 47.71 μmol·h −1 , which was 2385.50 times higher than that of CN NSs. Moreover, 3-NPS/CN also exhibited excellent PHE activity in seawater, with a rate of 8.99 μmol·h −1 . The photoelectrochemical, steady-state photoluminescence (PL), time-resolved PL (TR-PL), steady-state surface photovoltage (SPV) and time-resolved surface photovoltage (TPV) techniques were performed to investigate the charge separation and migration behaviors of various photocatalysts. Based on the characterization results, our group proposed a reasonable PHE mechanism. In the NPS/CN photocatalysts, photo-induced electrons rapidly migrated from the conduction band (CB) of CN NSs to the CB of NPS NSs due to the potential difference and strong interfacial electronic coupling between the two materials. The photogenerated electrons accumulated on the CB of the NPS NSs component efficiently reduced protons to generate H 2 molecules. Concurrently, photogenerated holes on the valence band (VB) of CN NSs and NPS NSs were consumed with the assistance of triethanolamine (TEOA) molecules. This study presents a facile method for fabricating 2D/2D heterostructured photocatalysts, which hold promise for efficient and robust implementation in energy applications.

NiPS 3 electrodes usually suffer from aggregation large volume changes, low electrical conductivity , and huge volume changes in bulk phase. These significantly decrease the electron transport efficiency, resulting in the sluggish reaction kinetics of supercapacitors during cycling. Herein, we designed and produced hollow porous nitrogen-doped carbon capsules (N-Cc), which are used as a conductive matrix and dispersed growing substrate for NiPS 3 . Finally, NiPS 3 nanosheets were successfully grown in situ on N-Cc by chemical vapor deposition method. The specific capacitance of the highly integrated N-Cc@NiPS 3 -1.0 electrode structure is notable, at 590 C g −1 . The assembled N-Cc@NiPS 3 -1.0//AC asymmetric supercapacitor (ASC) delivers an energy density of 55.42 Wh kg −1 at power density of 750.05 W kg −1 and an outstanding stability with 89.9 % of retention rate for 8000 cycles. It should be noted that the performance of the N-Cc@NiPS 3 -1.0 here surpasses most of previously reported similar materials.

The integration of photocatalytic processes to simultaneously convert plastic waste into valuable chemicals and generate green hydrogen represents a significant advancement in the field of renewable energy and environmental remediation. The study demonstrated the potential of solar-powered photocatalytic processes to convert plastic waste, specifically polylactic acid (PLA), into value-added chemicals like pyruvate while simultaneously producing green hydrogen. The use of a CZS/NiPS 3 heterojunction as a catalyst was pivotal, as it created an efficient interface for electron transfer, enhancing the overall photocatalytic activity. The CZS/NiPS 3 -20 % catalyst exhibited remarkable performance, producing 777.4 mmol/g of hydrogen over 10 h in a pretreated PLA solution. In a real PLA plastic system, the catalyst generated 506.41 mmol/g of hydrogen over the same period, showcasing its practical applicability. The catalyst facilitated the selective photoreforming of PLA into pyruvate, a high-value chemical, as confirmed by GC-MS analysis. This dual functionality-hydrogen production and chemical conversion-maximizes the utilization of photogenerated electrons and holes, improving the overall efficiency of the process. This research offers a strategy to address plastic pollution and boost the hydrogen economy by converting waste into valuable products and using seawater for clean energy.

Self-powered photodetectors have been attracting more and more attention due to the energy shortage issues around the world. As a type of layered van der Waals material, NiPS3 has garnered much attention in the realms of optoelectronics. In order to excavate the possible self-powered potential of this material, we utilized the asymmetric electrode contact design in the device structure of a NiPS3-based photodetector. Photoelectric characterization of the device presented a broadband spectral detection range from 254 nm to 1020 nm. The device showed a zero-bias photoelectric response with responsivity and detectivity of 2.3 mA W−1 and 6.2 × 109 Jones, respectively. Moreover, this photodetector exhibited a response time of less than 40 ms for both rising and decay times and low dark current (∼pA). The self-powered phenomenon is possibly attributed to the unbalanced Schottky barriers of the two electrode contacts. This study provides a potential route for van der Waals material-based photoelectric devices applied in wearable photoelectronic devices and green energy economy.

With the rapidly increasing demands of industrial material processing, biomedical sensing, light detection, and high-speed communication, various novel two-dimensional (2D) materials have been synthesized and employed in ultrafast fiber laser generation due to their advantages of easy processing characteristics, desirable structures and excellent nonlinear optical properties. However, finding an efficient 2D material-based saturable absorber (SA) with the capacity of both high stability and excellent working property performance remains a challenge. Herein, high-quality NiPS3 crystals, from the metal phosphorus trichalcogenide (MPT3) family, were synthesized by a modified chemical vapor transport (CVT) method and a few-layer NiPS3 nanosheet SA was easily obtained using a direct liquid-phase exfoliation method. Different from other 2D materials, ultrathin NiPS3 nanosheets display a good stability. Moreover, a passively Q-switched operation and dual-wavelength mode-locked pulse output were proposed based on a NiPS3-SA erbium-doped fiber (EDF) laser. In the passively Q-switched operation, the maximum peak power was 6.40 mW with a maximum pulse energy of 29.66 nJ. It is also worth noting that dual-wavelength pulse output was achieved in passively mode-locked pulse generation. These results not only supply other choices of SAs for pulse generation, but also provide guidance to extend other possible applications of the MPT3 family for nonlinear optics.

Electrocatalysts for oxygen reduction reactions (ORR) and oxygen evolution reactions (OER) are highly crucial and challenging toward the energy storage and conversion technologies such as fuel cells, metal-air batteries and water electrolysis. To replace noble-metal based catalysts and boost catalytic performance of carbon-based materials, we initially develop the nickel, phosphorus, sulfur and nitrogen co-modified mesoporous carbon (NiPS 3 @NMC) as a bifunctional oxygen electrocatalyst. The performance for ORR (half-wave potential at 0.90 V) and OER (10 mA cm −2 at 1.48 V) surpasses those of Pt/C coupled with IrO 2 catalysts and most of the non-precious metal based bifunctional electrocatalysts reported in related literature. Moreover, the electrochemical durability is also confirmed by accelerated durability tests (ADTs) and long-term chronoamperometry (CA) tests. We demonstrated that the interfacial effect between NiPS 3 quantum sheets (QSs) and NMC substrates by thermal activation contributed to the enhanced oxygen electrode bifunctionality with more active sites, due to the electrons-donating from nickel, phosphorus and sulfur elements and relatively enriched pyridinic type N. Such excellent overall performance highlights the potential application of NiPS 3 QSs and NMC composites as the materials on energy conversion and storage.

Two-dimensional (2D) layered NiPS 3 has drawn considerable attention as a promising anode candidate for alkali-ion batteries, boasting tunable electronic configurations and high theoretical capacity (∼1296.8 mAh g −1 ). However, two fundamental challenges impede its practical application: irreversible nanosheet restacking during synthesis seriously compromising Na + ion diffusion, and structural collapse during cycling causing catastrophic capacity fade. Addressing these limitations, we proposed a metal–organic framework (MOF)-mediated structural transformation strategy to construct hierarchical hydrangea-like NiPS 3 /C microspheres through carbonization and phospho‑sulfurization of Ni-BPDC (BPDC = 4,4′-biphenyldicarboxylic) precursor. The unique architecture manifested multiple advantageous features: (i) randomly oriented NiPS 3 nanosheets ensuring abundant electrochemical active sites and efficient electrolyte permeation; (ii) interconnecting conductive carbon networks enabling ultrafast electron transport; and (iii) spatially distributed carbon nanoparticles helping accommodate volume changes. Benefiting from these synergistic effects, the developed NiPS 3 /C electrode delivered outstanding electrochemical performance, including high specific capacity (1107.8 mAh g −1 at 0.1 A g −1 ) and superb cycling stability (98.2% capacity retention after 1000 cycles at 5.0 A g −1 ). Through in-situ / ex-situ structure diagnostics, we decoded the dynamic phase evolution during sodiation/desodiation, revealing a conversion-alloying mechanism. This work established a general strategy for designing high-performance MOF-derived anode materials for energy storage systems.
