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.

Replacing the sluggish oxygen evolution reaction (OER) with thermodynamically favorable urea oxidation reaction (UOR) is an appealing tactic in the energy-saving water splitting system. Herein, by a facile composite electrodeposition method, an electrocatalyst with Mo particles anchored on the Ni-P matrix (Mo/Ni-P) was fabricated and utilized for urea-assisted water electrolysis of hydrogen production. As expected, the urea-involved electrolytic cell with the as-obtained Mo/Ni-P served as both the anode and cathode merely needs a voltage of 1.55 V to sustain a current density of 50 mA cm −2 (0.16 V less than that of the conventional water splitting at 50 mA cm −2 ) and can maintain the stability for 12 h. Additionally, the solar-driven urea-assisted water electrolysis system was constructed under lab conditions and solar-hydrogen-electricity energy conversion processes were also simulated. Moreover, it was demonstrated that tungsten (W) particles can also serve as an accelerant for promotion both the hydrogen evolution reaction (HER) and UOR activity of pristine Ni-P. This work will present a facile method for rational integration of metal particles with Ni-P layer for highly efficient electrocatalysts applied in economic production of H 2 .

In this paper, the effects of surfactants such as PEG, CTAB and their combination (PEG: CTAB) on the microstructure and corrosion resistance of Ni-P-Si 3 N 4 composite coating were systematically studied. The electrochemical test shows that adding PEG or CTAB can reduce the coating defects and improve the corrosion resistance. When PEG and CTAB are used in combination, they show synergistic effect, which further enhances the compactness and corrosion protection of the coating. Among them, when the composite ratio is 3:1 (CTAB: PEG), the corrosion current density is significantly reduced, and the stability of the coating in corrosive medium is improved.

Graphical Take a Ni : NiO@Ni-P nanosheet arrays behave as efficient electrocatalyst benefiting from the synergistic effect between NiO and Ni-P. As a durable 3D catalytic electrode for oxygen evolution reaction, NiO@Ni-P/Ti exhibits a high activity achieving a geometrical catalytic current density of 10 mA cm −2 at an overpotential of 292 mV in 1.0 m KOH. Cost-effective and highly-efficient electrocatalysts for the oxygen evolution reaction are crucial for electrolytic hydrogen production. Here, we report core–shell NiO@Ni-P nanosheet arrays as a high-performance 3D catalyst for water oxidation electrocatalysis. Such nanoarrays demand overpotentials of 292 and 350 mV to drive geometrical catalytic current densities of 10 and 100 mA cm −2 , respectively, with an activity superior to its NiO and Ni-P counterparts. Notably, this catalyst also shows a high long-term electrochemical durability with a Faradaic efficiency of 98.1 %. Density functional theory calculation reveals that the superior activity benefits from the synergistic effect between NiO and Ni-P.

Developing electrocatalysts based on transition-metal carbides that can be utilized for commercial water splitting is a challenging endeavor. To address this challenge, we employed a novel approach that merged phase-inversion tape-casting and sintering, subsequently implementing a simple and efficient electrodeposition process, to synthesize Ni-activated and Ni–P-activated titanium carbide (Ni/TiC, Ni–P/TiC) ceramic electrodes as water splitting catalytic cathodes and anodes. These self-supported Ni/TiC and Ni–P/TiC electrodes are binder-free with abundant finger-like pores, which contribute to the formation of highly conductive skeleton and more exposed active sites for direct water splitting. These catalysts exhibit outstanding performance, superior to many reported bifunctional nickel-based catalysts supported on other substrates. Moreover, the exceptional electrocatalytic performance of the Ni/TiC and Ni–P/TiC catalysts is attributed to the synergistic effect between Ni oxides (phosphides) and TiC, as revealed by density functional theory (DFT) calculations. This self-template strategy paves the way for fabricating industrially applicable electrodes to generate hydrogen and oxygen through water splitting.

The extraction and transportation of oil and gas pose significant challenges due to corrosive environments, particularly hydrogen sulfide (H 2 S) exposure. This study investigates the use of polytetrafluoroethylene (PTFE) to enhance the corrosion resistance of nickel‑phosphorus (Ni P) coatings in H 2 S-rich environments. Electroless deposition was employed to prepare Ni-P/PTFE coatings, which were then subjected to simulated H 2 S corrosion tests. Results indicate that the incorporation of PTFE led to a more uniform Ni P coating with reduced porosity, significantly improving corrosion resistance. The coatings exhibited enhanced protective performance by stabilizing corrosion product layers and preventing the formation of corrosion channels. Ni-P-PTFE coatings overcame the existing research challenge of Ni P coatings' corrosion in H2S environments, showing no penetration of the corrosive medium into the substrate after 720 h of immersion. The corrosion rate of the coating is only 0.0261 mm/year, only 4.27 % of the corrosion rate of the L245NS substrate in the early stage of corrosion. Moreover, after characterization by SEM, XRD and XPS, it was found that the presence of PTFE altered the corrosion mechanism, promoting the formation of stable nickel sulfide and oxide layers on the surface. This study sheds light on the mechanisms underlying PTFE-enhanced corrosion resistance in Ni P coatings, offering promising implications for extending the lifespan of equipment in the oil and gas industry.

Ever-growing efforts have been devoted to developing cost-effective and earth-abundant electrocatalysts with high-performance in biosensing and energy energy conversion. In this work, amorphous nickel-phosphorus (Ni-P) nanoparticles anchoring on Ni foam (Ni-P/NF) were prepared through a facile electroless deposition approach. The morphology and composition were characterized by scanning electron microscopy, x-ray diffraction and x-ray photoelectron spectroscopy. As an integrated anode, Ni-P/NF exhibits high performance towards glucose electrochemical sensing, with a high sensitivity of 13.89 mA mM−1 cm−2, a low detection limit of 1 µM, a wide detection ranges from 2 µM to 0.54 mM, and a quick response (<10 s), as well as good selectivity and reliability for real sample analysis in human serum. In addition to electrocatalytic glucose oxidation, Ni-P/NF shows remarkable catalytic activity towards oxygen evolution reaction (OER) in alkaline solution and it only needs an overpotential of 360 mV to afford 50 mA cm−2. Moreover, Ni-P/NF shows excellent durability under alkaline OER condition. All these results demonstrate Ni-P/NF as highly efficient integrated anode in both biosensing and energy conversion.

The exploration of highly efficient catalysts for electrochemical hydrogen and oxygen production via water splitting is very significant for providing affordable clean energy and reducing the reliance on conventional fossil fuels. Herein, we develop an efficient method to boost the electrocatalytic performance of Pt mesoporous nanoparticles (Pt MNs) for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) by a facile Ni, P co-incorporation strategy. The co-incorporation of Ni and P atoms in a Pt crystal structure can effectively modify its electronic structure, which contributes to the superior catalytic ability toward HER. We also demonstrate that the as-fabricated PtNiP MNs could occur surface partial oxidation under oxidizing potentials to in situ form OER electroactive oxides/hydroxides species. The unique mesoporous structure and metal–nonmetal ternary alloyed composition make the PtNiP MNs a promising HER–OER bifunctional electrocatalyst for overall water splitting in alkaline media.

High-efficiency electromagnetic interference (EMI) shielding fabrics with strong absorption and low reflection characteristics are urgently demanded to address the increasing electromagnetic radiation pollution, but it is still challenging to integrate these features onto single fabric. Herein, an all-in-one asymmetric conductive structure was constructed on 3D polyester fiber-based spacer fabric through a successive in situ polymerization of polyaniline and followed by localized electroless Ni–P plating process. Thanks to the synergistic effect of microwave absorbing layer of low-conductivity polyaniline coating and shielding reflection layer of highly conductive Ni-P plating, the incident electromagnetic waves undergo a process of “absorption–reflection–reabsorption” and are dissipated as much as possible when they propagate into the composite fabric. The resultant composite fabric shows a superior EMI SE over 60 dB within 18–40 GHz, whereas the EMI SE from reflection is only 1.6 dB, and the average reflectivity is as low as 0.31, which indicates that 69% of electromagnetic waves are absorbed in the fabric. Interestingly, the porous structure of substrate and highly conductive Ni–P plating also endow this fabric with good thermal insulation and low infrared emissivity, resulting in an excellent infrared stealth performance. This study provides a facile and feasible approach for the development of high-efficiency and multifunctional EMI shielding fabric with low-reflection characteristics that holds great promise for application in civil and military fields.

To improve the combustion efficiency of widely used micro-aluminum (μAl) particle, enhancing its ignition and combustion performances is a critical issue via breaking through the intrinsic Al 2 O 3 layer covering the Al-core. This study proposed a facile in-situ ‘one-pot’ electroless plating method to functionalize the surface of μAl particles with ternary-shelled nickel-phosphorus-copper alloy coating and furthermore investigated the thermochemical and ignition/combustion behaviors of energetic core–shell composites (defined as Al@Ni-P-Cu). The microstructure characterization results of Al@Ni-P-Cu demonstrated that a spherically distributed triple-shell Ni-P-Cu alloy with the thickness of 129 nm was tightly coated on μAl particle surface. Through TG-DSC analysis, the Al@Ni-P-Cu composites exhibited improved heat release (7597.7 J/g) and decreased initial oxidation temperature (814.3 °C) in comparison to that of μAl particle with 949.2 J/g and 960.1 °C, respectively. The Al@Ni-P-Cu exhibited extremely shorter laser ignition delay time of 36.3 ms under 1 MPa O 2 atmosphere, reducing by 86.86% compared with that of raw μAl particles (276.3 ms); and its maximum flame temperature could reach up to 1588.93 °C, increasing by 243.36 °C compared with that of μAl (1345.57 °C). The drastic improving performances were attributed to the synergistic effects of surface/interfaces reactions along with heat release in the core–shell structure, resulting in enhanced mass and heat transfer to facilitate the combustion of internal Al-core.

In this work, modified Cr 3 C 2 and two-dimensional layered WS 2 were deposited within a Ni-P plating layer via pulse electrodeposition, synthesizing a novel Ni-P-Cr 3 C 2 /PANI@WS₂ plating on N80 carbon steel. The synergistic effects of Cr 3 C 2 /PANI (polyaniline-coated Cr 3 C 2 ) and WS 2 on the coating were investigated. The results indicate that adding the aforementioned components considerably enhances the surface morphology, mechanical characteristics, and corrosion resistance of the composite coating, as shown below: The Ni-P-Cr 3 C 2 /PANI@WS 2 plating exhibited outstanding mechanical properties, with a microhardness of 800.16 HV, an average coefficient of friction of 0.143, a wear scar area of 67.70 µm 2 and a wear depth of 0.97 µm. Nanoindentation testing further indicates this composite coating possesses the highest hardness and elastic modulus, reaching 785.02 HV and 154.67 MPa respectively. Immersion testing in a 3.5 % NaCl solution demonstrates that the incorporation of Cr 3 C 2 /PANI and WS 2 significantly enhances the long-term corrosion resistance of the Ni-P plating. Moreover, the composite plating maintains excellent corrosion resistance even under acidic conditions, demonstrating its potential for demanding applications in aggressive environments.

The application of NiCo-LDHs in the hydrogen evolution reaction (HER) is rarely reported because it is usually served as an effective electrocatalyst for oxygen evolution reaction (OER) owing to the essential chemical and electric structure features. It still is a challenge to realize the effective HER over NiCo-LDHs unless modified with noble metals . In this work, the noble-metal-free core–shell Co(OH) 2 @P-NiCo-LDH hybrid with dodecahedral hierarchical structure is prepared by the sacrificial template method along with subsequent phosphating process, which is available for the electrocatalytic HER. The fabricated Co(Ni) δ+ -P δ- bonding states on the surface of outer shell NiCo-LDH not only provide the abundant active centers but also reduce interfacial charge transfer resistance to enhance the HER activity. Meanwhile, the unique core–shell dodecahedral structure effectively avoids the agglomeration and restacking of NiCo-LDH nanosheets to improve the electrochemical stability. This work exploits a novel noble-metal-free modification strategy to expand the application of NiCo-LDH in HER.
