Nickel-based nanoparticles have been widely used in detection of glucose due to its multiple oxidation states and high stability in alkaline environment. In this work, amorphous nickel phosphate was supported by Co-based zeolitic imidazolate framework (ZIF-67) through ion exchange to prepare Ni 3 (PO 4 ) 2 @ZIF-67 composites as the electrode material . In comparison to glassy carbon electrode (GCE), Ni 3 (PO 4 ) 2 /GCE and ZIF-67/GCE, the Ni 3 (PO 4 ) 2 @ZIF-67/GCE showed significantly enhanced performances in electrocatalytic oxidation of glucose. The great improvement on glucose oxidation current could be ascribed to the unique structure of Ni 3 (PO 4 ) 2 @ZIF-67, the mutual promotion between Ni(III)/Ni(II) and Co(IV)/Co(III) interfacial redox reactions and increased surface areas. Under optimum conditions, as-prepared Ni 3 (PO 4 ) 2 @ZIF-67/GCE showed an ultra-high sensitivity of 2783 μA mM −1 cm −2 with a wide linear ranged from 1.0 μM to 4.0 mM, and a low limit detection of 0.7 μM at a signal-to-noise ratio of 3. Moreover, Ni 3 (PO 4 ) 2 @ZIF-67/GCE were successfully applied to detect glucose of human serum with good recoveries (92–109%), which indicated that Ni 3 (PO 4 ) 2 @ZIF-67 can found application in the clinical detection.

The ultra-long nanowires of nickel phosphate were synthesized by a simple, template-free hydrothermal method . Scanning electron microscopy and transmission electron microscopy show the morphology of ultra-long nanowires with lengths ranging from 20 to 30 μm, diameters in the range of 60 ± 20 nm, and the high length/diameter ratio of about 350. X-ray diffraction, X-ray photoelectron spectroscopy, high resolution transmission electron microscopy and selected area electron diffraction pattern confirm that the ultra-long nanowires are composed of Ni 3 (PO 4 ) 2 and NiHPO 4 ∙3H 2 O. The formation mechanism for the ultra-long nanowires of nickel phosphate is discussed reasonably. The ultra-long nanowires of nickel phosphate exhibit excellent electrocatalytic activity towards glucose oxidation . The cross of nanowires results in more interspaces and active sites. As a result, they show the similar behavior of microelectrodes with low background current, low capacitance current and high catalytic current due to the high specific surface area, efficient charge transfer and fast diffusion of reactants and products. It may find potential applications for fuel cells.

Electrochemical energy storage devices (EESDs) are the elementary key to fulfilling the demands of renewable energy storage as compared to other conventional energy storage devices, which are powerless to achieve the worldwide needs of energy owing to their low energy density (ED) (batteries) and power density (PD) (supercapacitor). This study presents the cost-effective assembly of high-performance Yumberry-like nickel phosphate (Ni 3 (PO 4 ) 2 ) aggregates for hybrid supercapacitors, addressing the demand for efficient energy storage devices. The Ni 3 (PO 4 ) 2 micro-size particles were synthesized via a hydrothermal method and characterized using various advanced techniques. The electrochemical performance of these particles was evaluated in a three-electrode system, demonstrating an excellent specific capacity of 549.19 C/g at a scan rate (SR) of 5 mV/s. The assembled supercapattery device exhibited a high ED of 88.03 Wh/kg at a current density (CD) of 2 A/g and a PD of 9.333 kW/kg at 14 A/g CD, with good cyclic stability (98.7%) after 2000 cycles. Dunn's model and power law analysis confirmed the device's hybrid energy storage behavior, highlighting the contribution of both capacitive and diffusive processes. This work offers a sustainable approach to developing high-performance supercapattery devices with potential applications in energy storage.

The development of low-cost, high-performance, and stable electrocatalysts for the sluggish oxygen evolution reaction (OER) in water splitting is essential for renewable and clean energy technologies. Herein, the interconnected nanoarrays consisting of Co–Ni bimetallic metaphosphate nanoparticles embedded in a carbon matrix (Co 2− x Ni x P 4 O 12 -C) are fabricated through a mild phosphorylating process of cobalt–nickel zeolitic imidazolate frameworks (CoNi-ZIF). Density functional theory calculations reveal moderate adsorption of oxygenated intermediates on the doping Ni site, and current density simulations imply homogeneous and higher current density due to the morphology integrity of the interconnected metaphosphate nanoarrays. As a consequence, the optimized Co 1.6 Ni 0.4 P 4 O 12 -C affords a superior OER activity (η = 230 mV at 10 mA cm −2 ) and long-term stability in alkaline media (1 m KOH) that are comparable to most reported catalysts. The strategy for balancing the doping effect and morphology effect provides a new perspective when designing and developing highly efficient electrocatalysts for energy conversion and storage applications.

In recent years, selective metallization on polymer surfaces has attracted considerable attention due to its excellent properties and wide applications. This paper reports that copper phosphate (Cu3(PO4)2) or nickel phosphate (Ni3(PO4)2) was selected as laser-active material to successfully fabricate metallic patterns on ordinary polymer substrates by laser direct activation and electroless plating. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) were utilized to characterize the interaction mechanism between a nanosecond-pulsed laser (355 and 1064 nm wavelengths) and Cu3(PO4)2 or Ni3(PO4)2. It was found that after 355 or 1064 nm laser activation with appropriate parameters, Cu+ was generated from Cu3(PO4)2, and NiO was generated from Ni3(PO4)2. At the same time, Cu+ or NiO adsorbed on the porous sponge-like microstructure of modified polycarbonate (PC), respectively, and acted as catalytic active centers to realize selective copper deposition in the laser-activated zone. Furthermore, the obtained copper layers were confirmed to possess good selectivity, electrical conductivity, and high adhesion strength (the highest grade of 5B). Moreover, from comparisons of Cu3(PO4)2 with Ni3(PO4)2 and of 355 nm laser activation with 1064 nm laser activation, the 1064 nm laser activation of Cu3(PO4)2 produced the most catalytic seeds (Cu+) and had the best catalytic effect.

Electrochromic devices have gained great attention owing to their potential application in fields such as smart windows, glassware, and low-cost displays. Recent investigations have shown that the nickel phosphate films (NiHPO4·3H2O, NiHP films) are highly promising for the fabrication of large-area smart windows with large optical modulation. However, the performances such as the color switching time, coloration efficiency and cycling stability of such films are not ideal and need further investigations. In this study, we propose a layer-by-layer electrodeposition method for the fabrication of a composite metal phosphate film. A CoHPO4 layer is first deposited on the ITO glass as the frame, and then NiHPO4 is further electrodeposited on the CoHPO4 frame as an electrochromic active layer. The resulting film with NiHPO4 on CoHPO4 (CoHP/NiHP film) exhibits an optical modulation of 65.55%, a fast color switching time (tc/tb 2.0/8.5 s, the coloring time is three times faster than that of the pure NiHPO4 film), a high charge capacity (81.36 mF cm−2), excellent memory effect (10.53% attenuation after 5000 s), a high coloration efficiency (140.37 cm2 C−1, it is twice that of the pure NiHPO4 film) and 5 times improved outstanding cycling stability compared with the pure NiHPO4 film (1400 cycles with retained performance). The uniform nanosheet morphology of CoHPO4 provides a large active area for the electrochromic response. Meanwhile, the electrochemical investigations indicate that, compared with the pure NiHPO4 film, the NiHPO4 on CoHPO4 composite structure shows much faster electrical dynamics with diffusion coefficient values of OH− increased by an order of magnitude. The larger active area and much faster electrical dynamics promote the electrochromic performances of the metal phosphate films. Our findings may help in the development of metal phosphate films with high electrochromic performances. The layer-by-layer electrodeposition strategy may help to develop new types of electrochromic materials.

Seawater electrolysis, benefiting from the closeness to coastal areas, is recognized as a promising alternative for hydrogen (H 2 ) production to replace conventional technologies. However, the effectiveness of this method is limited by anode catalysts that exhibit high energy consumption and short lifespans due to chloride-induced chemical corrosion. Herein, we propose a hierarchical Ni phosphate@NiFe layered double hydroxide on Ni foam (NiPO x @NiFe LDH/NF) towards alkaline seawater oxidation (ASO). In terms of its unique hierarchical structure, NiPO x @NiFe LDH/NF delivers an industrial current density reaching up to 1 A cm −2 with 352 mV overpotential. Electrochemical experiments and in situ characterizations reveal that self-released PO 4 3− can act as a robust barrier for chloride ions adsorption through strong electrostatic repulsion, promoting unstable activity phase NiOOH drive at 1 A cm −2 for 600 h, farther than NiFe LDH/NF (75 h). Moreover, the honeycomb-like NiFe LDH shell facilitates the rapid and uniform release of O 2 bubbles, which enhances the mechanical stability of the electrode during long-term ASO. In general, this work offers valuable potential for designing an advanced anodic electrode with remarkable electrochemical performance and superior anti-corrosion for ASO.

Electrochemical reconstruction typically generates powerful active sites for the oxygen evolution reaction (OER). However, engineering effective reconstruction strategies to manipulate the in situ formation of desired catalytically active surfaces, generate powerful active sites, and enhance their catalytic performance remains a challenge. Herein, leveraging the oxidation-potential-assisted precipitation etching, a heterostructure of NiFeOOH/NiFe phosphate was meticulously engineered to achieve highly efficient OER. During the electrochemical reconstruction, the leaching of inactive PO43– species in NiFe phosphate facilitates the exposure of more Ni and/or Fe species and creates more pores, thereby contributing to the formation of a NiFeOOH layer on the surface of NiFe phosphate. The resultant NiFeOOH/NiFe phosphate exhibits excellent OER activity with an overpotential of 205 mV at 50 mA cm–2 in an alkaline electrolyte. The theoretical calculations reveal that the heterostructure of NiFeOOH/NiFe phosphate weakens the thermodynamic barrier from *O to *OOH, thus enhancing the OER activity. The present proof-of-concept study introduces a leaching engineering approach to facilitate further exploration and development of highly efficient energy-related applications.

To enhance the hydrogen production performance and photo-corrosion resistance of ZnS and CdS based photocatalysts without relying on noble metals such as platinum, ruthenium, or gold, this study optimizes the molar ratio between Cd and Zn in Zn x Cd 1-x S solid solutions. The resulting Zn 0.4 Cd 0.6 S nanorod-shaped solid solutions exhibit superior visible-light photocatalytic activity. A non-precious metal Ni 3 (PO 4 ) 2 nano-thin layer is uniformly deposited onto the surface of the Zn 0.4 Cd 0.6 S solid solution via a room-temperature chemical co-precipitation method. This modification not only prevents oxidative photo-corrosion but also facilitates the oxidation and reduction of water during the photocatalytic surface process, significantly enhancing both the stability and hydrogen production performance of the composite catalyst. Experimental results demonstrate that the performance improvement of Zn 0.4 Cd 0.6 S by the Ni 3 (PO 4 ) 2 cocatalyst is markedly greater than that achieved with the traditional Pt cocatalyst. The maximum hydrogen production rate of the composite catalyst reaches 119.72 mmol·g⁻¹·h⁻¹, with an accumulated hydrogen production of 340.33 mmol·g⁻¹ after 3 hours. After 25 hours of photocatalytic cycling experiments, the hydrogen production rate remains at 95.95 mmol·g⁻¹·h⁻¹, approximately 80.14 % of the initial rate. The apparent quantum yield of Z4C6S-5NPO attains 61.8 %, with high value in ZnCdS-based photocatalysts. These results are promising and offer valuable insights for the development of low-cost, highly stable, and efficient composite photocatalysts.

Low-cost and highly active water oxidation electrocatalysts are increasingly demanded to improve the efficiency of water splitting. Herein, for the first time, we developed a facile strategy to design a three-dimensional flower-like cobalt nickel phosphate as such an electrocatalyst. The cobalt nickel phosphate was directly supported on Ni foam ((Co 0.5 Ni 0.5 ) 3 (PO 4 ) 2 /Ni) via a simple two-step hydrothermal method.
This method offers several advantages including low cost, facile synthesis and binder-free. Benefiting from its three-dimensional flower-like nanostructure with a big specific surface, high conductivity and the synergic effect of metal ions are the as-synthesized (Co 0.5 Ni 0.5 ) 3 (PO 4 ) 2 /Ni reveals excellent oxygen evolution reaction activity in alkaline electrolyte. It exhibits a low overpotential of 273 mV to reach a current density of 10 mA cm −2 and a Tafel slope of 59.3 mV dec −1 in 1.0 mol L −1 KOH. Notably, the (Co 0.5 Ni 0.5 ) 3 (PO 4 ) 2 /Ni also operates efficiently in 30 wt% KOH, capable of affording an anodic current of 10 mA cm −2 at a lower overpotential of 246 mV and retains its catalytic performance for at least 30 h.

Conducting polymers are commonly used as precursors for preparing carbon-based catalysts and have been used in electrocatalytic water splitting. However, so far, most of the catalytic materials synthesized with the assistance of high polymer conducting polymers are non-self-supporting and have only a single-function catalytic effect. Therefore, it is an inevitable trend to synthesize a bifunctional self-supported, highly efficient and long-stable water splitting catalyst. Herein, a self-supporting polypyrrole precursor PPy-PW 12 was prepared by electrodeposition with phosphotungstic acid as a dopant. In addition, the PPy-PW 12 precursor was then calcined. The as-prepared W/Ni 3 (PO 4 ) 2 @NC/NF electrocatalyst exhibits admirable HER and OER performances with overpotentials of 48 mV for HER and 236 mV for OER to reach a current density of 10 mA cm −2 in 1.0 M KOH solution. Additionally, when W/Ni 3 (PO 4 ) 2 @NC/NF is used in overall water splitting as a bifunctional catalyst, it needs only 1.53 V to deliver a current density of 10 mA cm −2 , which is superior to typically integrated Pt/C and RuO 2 counterparts. Our work offers a facile strategy to apply W/Ni 3 (PO 4 ) 2 @NC/NF as practical bifunctional electrocatalysts for large-scale water splitting.
