To span the inherent application limitation of state-of-the-art catalysts for the chemical transformation of biomass derivatives, here, we formulate a series of Pr–Ni–P catalysts for the hydrogenation transformation of biomass-derived levulinic-acid, furfural and maleic anhydride. With comprehensive characterizations, Pr–Ni–P samples are verified as (PrPO4)m/Ni2P nanocomposites with a molar ratio (m) in the range of 0.24–11.0. In comparison with the poor catalytic performance of Ni2P, a ten-fold enhancement in TOF up to 0.45 s−1 and at least five-time promotion on the yield of objective products up to 91–98% are achieved by introducing proper amounts of PrPO4 to form reusable (PrPO4)m/Ni2P nanocomposites. Surface chemistry and kinetic mechanism studies further disclose that the cooperative catalytic function of two components, in particular the exclusive capability of PrPO4 to activate hydrogen, is responsible for the promoted hydrogenation transformation of biomass derivatives via a quick Langmuir–Hinshelwood process over (PrPO4)m/Ni2P. These findings imply that an easily obtainable, cost-affordable and robust rare earth phosphate like present PrPO4 could be a potential replacement catalytic component for the traditional metal catalyst in the hydrogenation transformation reactions of biomass derivatives, which was also worth noting as a new kind of basic material for other green mass-transformation techniques involving hydrogen activation processes such as corresponding optical and electrical transformations.

Developing low-cost and high-performance catalysts instead of Pt-based noble metal materials for alkaline HER is essential for sustainable clean technologies. However, the high energy barriers of H 2 O dissociation and intermediate *H lead to the low efficiency and the difficultly of the alkaline HER. Herein, the hierarchical Al-CoP/Ni 2 P on Ni foam (Al-CoP/Ni 2 P@NF) was successfully prepared using interface and doping engineering strategies. The heterostructure, Al doping, and hierarchical morphology significantly improve the electronic configuration and the active surface area of the compound. Notably, the Al-doping compound exhibits excellent HER performance in 1.0 M KOH, achieving a current density of 10 and 20 mA cm −2 at 55 and 72 mV overpotential, respectively, with a Tafel slope of 55.6 mV dec −1 . As an overpotential of 72 mV is performed, the current density 20 mA cm −2 keeps unchanged for even 24 h in alkaline water electrolysis. DFT calculations further reveal that Al-induced partial electron redistribution of CoP/Ni 2 P, thereby optimizing Δ G H* and reducing the energy barriers of H 2 O dissociation.

Doping hetero-atoms into non-noble metal phosphides is an important strategy for enhancement of hydrogen evolution reaction (HER) performance. Herein, we prepare a self-supported F-doped CoP/Ni 2 P nanowire arrays grown on Ni foam by using a strategy with three steps including hydrothermal reaction , fluorination , and low-temperature phosphorization. The F-CoP/Ni 2 P nanowire consists of a well-defined crystalline core and a thin amorphous surface layer. The F-doping and amorphous surface layers effectively expose a large number of active sites, optimize the electronic configuration of Ni, Co and P on the surface, and promote the electron transport performance. As a result, the prepared F-CoP/Ni 2 P@NF-II exhibits excellent electrocatalytic activity for HER in alkaline electrolyte with a lower overpotential of 75 mV at 10 mA cm −2 , a small Tafel slope of 54.8 mV dec −1 , and good durability. This work provides a simple method for developing transition metal phosphate-based catalysts towards hydrogen evolution reaction .

The development of a low-cost, accurate sensing strategy for trace levels of chloramphenicol (CAP) residues in food is crucial but remains challenging. In this study, a high-performance electrochemical platform was developed to detect CAP in animal-derived foods using Ni 2 P embedded N, P-co-doped mesoporous carbon nanospheres (Ni 2 P@N,P-MCS). The Ni 2 P@N,P-MCS material, with a unique mesoporous structure and large specific surface area, exhibited excellent adsorption properties. The N, P-co-doped heteroatoms enhanced the electric conductivity and active centers of MCS, facilitating fast mass transport and electron transfer. The introduction of Ni 2 P increased the active sites and enhanced the electrocatalytic activity. Leveraging these advantages, the electrochemical sensor based on Ni 2 P@N,P-MCS demonstrated outstanding detection performance with a wide linear range from 0.04 to 250 μM and a low limit of detection of 12 nM. The sensor also showed good reproducibility, stability, and anti-interference properties. Furthermore, the sensor was successfully tested in milk and pork samples, showing satisfactory recovery rates and indicating its feasibility for real sample analysis.

Electrochemical water splitting is a promising approach for sustainable hydrogen production, but the oxygen evolution reaction (OER) remains a bottleneck due to sluggish kinetics, poor activity, and limited stability and scalability. Here, a Mo 2 N-functionalized nickel is designed foam (NF@Mo 2 N) and subsequently transform into a Mo 2 N/NiSe/Ni 2 P multi-phase heterostructure through selenization and phosphorization, to address these challenges. The optimized NF@Mo 2 N/NiSe/Ni 2 P catalyst integrates three key strategies: (I) functionalizing NF with Mo 2 N to enhance conductivity and charge transfer, (II) engineering a collaborative multi-interface heterostructure to optimize active sites and reaction kinetics, and (III) precisely controlling phase formation through selenization and phosphorization to mitigate surface reconstruction and ensure long-term stability. The catalyst not only achieves an overpotential of 242 mV@10 mA cm −2 and remarkable stability over 350 h, but also achieves a low overpotential of 395 mV at a high current density of 800 mA cm −2 , outperforming the pristine other control samples. Theoretical analysis reveals that the Mo 2 N-stabilized NiSe/Ni 2 P heterostructure on NF enhances conductivity and optimizes adsorption energies of OER intermediates, leading to improved catalytic performance and stability. This work provides a new strategy for designing high-performance, non-precious metal OER catalysts for industrial applications and advancing sustainable hydrogen production.

Urea electrolysis is critically important for the advancement of sustainable and clean energy conversion technologies, addressing global energy shortages and environmental concerns. The urea oxidation reaction (UOR) poses a significant challenge due to its unfavorable thermodynamics, making it a pivotal step in urea splitting. The 6-electron transfer process of UOR presents a bottleneck due to its sluggish kinetics. Consequently, the development of efficient urea oxidation electrocatalysts and gaining insights into the electronic configuration of the central metal ion are of paramount significance in achieving high-performance urea-based energy conversion technologies. In this study, we report the successful synthesis of hierarchical Ni 2 P nanosheets@nanorods (P-Ni 2 P HNNs) as promising catalysts to enhance UOR efficiency. This catalyst is designed and constructed using a hexamethylenetetramine-hydrolytic coprecipitation-oxidation process and a straightforward phosphorus-substituted method. X-ray absorption fine structure spectroscopy indicates that the presence of P-modified metal centers is responsible for the elevated UOR activity of P-Ni 2 P HNNs, with the electronic structure of Ni n + significantly enhancing Ni―O―O bond coupling for rapid UOR kinetics. Thanks to the highly exposed Ni n + centers and the well-designed architecture, P-Ni 2 P HNNs exhibit superior UOR activity and stability, with a low overpotential of 132 mV at 10 mA∙cm −2 , a small Tafel slope of 33.7 mV∙dec −1 , and sustained durability for 6 h at 10 mA∙cm −2 . Furthermore, a two-electrode cell for overall urea electrolysis is assembled with a P-Ni 2 P HNNs-2/NF anode, yielding a low potential of 1.411 V at 10 mA∙cm −2 and a high current density of 100 mA∙cm −2 at 1.595 V. This study presents an effective and viable approach for designing and synthesizing high-efficiency nickel-based phosphide electrocatalysts, which could pave the way for cost-effective and energy-efficient electrochemical hydrogen production, and advance phosphide research for various energy-related applications.

Transition metal phosphides (TMPs) as advanced electrode materials for supercapacitors (SCs) have received great attention due to their excellent redox activity, high electrical conductivity and metalloid feature. In this work, we successfully synthesized hierarchical core–shell CoP/Ni2P nanosheets (NSs) on carbon paper through a facile deposition and phosphating method. The optimized hierarchical core–shell CoP@Ni2P nanosheet electrode shows a high specific capacitance of 2644 F g−1 at a current density of 1 A g−1. Meanwhile, three-dimensional (3D) α-Fe2O3 grown on carbon paper was also synthesized as a negative material by a hydrothermal and annealing treatment method, which manifests excellent performance of 539.2 F g−1 at 1 A g−1. Besides, an asymmetric supercapacitor (ASC) was assembled, using CoP/Ni2P nanosheets as the positive electrode and α-Fe2O3 as the negative electrode in 3 M KOH electrolyte, which exhibits an excellent energy density of 48.5 W h kg−1 at 793 W kg−1 and a capacity retention rate of 98.8% after 10 000 cycles. The excellent electrochemical performance and outstanding cycling stability of the asymmetric supercapacitor show its great potential application in future energy storage devices.

Constructing heterointerfaces in heterostructures could effectively enlarge the electroactive sites and enhance the interfacial charge transfer, and thus improve the electrocatalytic performances. Herein, free-standing porous Ni 2 P-Ni 5 P 4 heterostructured arrays are successfully prepared through in situ phosphating Ni(OH) 2 arrays by simply tuning the reaction temperatures. Contributing from the interfacial coupling effects of two phases, large surface areas, highly conductive support of carbon cloth substrates and unique free-standing arrays, Ni 2 P-Ni 5 P 4 heterostructured arrays show the enhanced kinetics and electrocatalytic performances for the hydrogen evolution reaction , oxygen evolution reaction and overall water splitting. Our research might offer insight into constructing heterophase junctions for efficient overall water splitting.

Main observation and conclusion Accurate determination of acetaminophen concentration is essential for studying the metabolic status of acetaminophen in clinical practice. In this study, nickel phosphide was used for electrochemical detection of acetaminophen for the first time. An electrochemical acetaminophen sensor based on Ni 2 P nanosheets was successfully constructed and the sensor showed many convincing properties: (a) a good linear range (0.5 μmol/L—4.5 mmol/L); (b) a moderate sensitivity (131.1 μA·mmol –1 ·L·cm –2 ); (c) a low detection limit (0.107 μmol/L). In addition, the sensor also showed excellent selectivity, robust stability and reliable repeatability. Further experiments demonstrate that the prepared sensor can be used for quantitative detection of acetaminophen in commercial medical drugs.

Water electrolysis represents a promising option for clean hydrogen production , but its overall efficiency is hindered by the sluggish oxygen evolution reaction (OER) with a complex electron transfer process. The construction of heterostructure has emerged as an effective approach to enhance the electrocatalytic performance for OER because of the improvement of exposed active surface and mass/charge transfer. In this work, we report the synthesis of hierarchical nanosheet-structured Ni 2 P-NiFe 2 O 4 as a robust OER catalyst via an annealing treatment and followed by in-situ phosphating process. The Ni 2 P-NiFe 2 O 4 electrocatalyst exhibits an overpotential of 305 mV to realize 100 mA cm −2 in 1.0 M KOH. Density functional theory calculations further confirm that the construction of heterostructure could optimize adsorption energy of oxygen-containing intermediates and reduce energy barrier during the OER process. This work may provide insights into the electrocatalytic activities of non-noble-metal-based catalysts and present an effective method for the preparation of complex structures.

The selective hydrogenation of quinoline is of great significance. To this end, we have developed an electrochemical system based on RuP 2 /Ni 2 P heterostructured electrodes, which utilizes water as the hydrogen source and quinoline/1,2,3,4-tetrahydroquinoline as the hydrogen carrier at room temperature, with a conversion of 97 % and a selectivity of 99 % in the quinoline hydrogenation reaction, and 96 % and a selectivity of 89 % in the dehydrogenation reaction of 1,2,3,4-tetrahydroquinoline. The RuP 2 /Ni 2 P heterogeneous interface significantly enhances the dissociation of water molecules. The advantages of this electrocatalytic system over conventional thermal catalysis are obvious in terms of environmental protection, energy efficiency and safety.
