As energy demand rises and environmental issues become more severe, various industries urgently need sustainable materials, and bifunctional catalysts are receiving increased attention. This paper employs a simple phosphating method to prepare Ni 2 P-supported reduced graphene oxide porous materials (Ni 2 P/rGO) as a bifunctional catalyst for photocatalytic degradation of pollutants and electrocatalytic hydrogen evolution reaction (HER). The introduction of polystyrene microspheres (PS) significantly improved the surface morphology of rGO, endowing Ni 2 P/rGO with excellent photocatalytic and electrocatalytic properties. The Ni 2 P/rGO composites material exhibits good degradation capabilities for diverse dyes and tetracycline hydrochloride (TC), with the best removal effects observed for methylene blue and tetracycline wastewater. Under visible light, the degradation efficiencies of methylene blue (MB) and TC pollutants within 100 min were 91 % and 83 %, respectively. Furthermore, with a low overpotential of 21.4 mV, a Tafel slope of 46.57 mV·dec −1 , and stability for 28 h, the Ni 2 P/rGO composite material demonstrates outstanding electrocatalytic hydrogen evolution performance in an alkaline environment. The above achievements mean that the current work has explored new trains of thought for the research and development of bifunctional catalysts.

Carbon nanofibers (CNs) supported by Pt and Ni 2 P nanoparticles (Pt-Ni 2 P/CNs) are successfully synthesized and explored as counter electrodes for dye-sensitized solar cells (DSSCs) for the first time. Pt and Ni 2 P nanoparticles are prepared by stabilization and carbonization of electrospun nanofibers , and subsequently controllable Pt and Ni 2 P nanoparticles are grown on surface of CNs obtained through redox reaction . A series of electrochemical measurements analysis confirm that the Pt-Ni 2 P/CNs composite have simultaneously superior electrocatalytic activity and enhanced electrical conductivity compared with those of individual CNs and Pt. Accordingly, DSSCs using the composite Pt-Ni 2 P/CNs as a counter electrode exhibit an excellent photovoltaic performance (power conversion efficiency of 9.11%), which is much higher than conventional Pt/CNs counter electrode (power conversion efficiency of 8.35%), owing to the collective effect of the high electrical conductivity originated from carbon nanofibers and superior electrocatalytic activity arising from Pt/CNs nanoparticles.

The Ni 2 P anode own high theoretical capacity but still suffer from big volume expansion thus resulting sluggish electrochemical kinetics in K-ion batteries. Herein, we design and synthesize the urchin-like Ni 2 P yolk-shell microspheres encapsulated into N-doped carbon shells (Ni 2 P@N-C) for the first time through one-step hydrothermal followed a phosphidation/carbonization process. The unique urchin-like morphology provides fast charge transfers to the active sites for improved K-ion storage at high current densities. The yolk-shell structure couples with the nitrogen-doping carbon layer to effectively relieve the volume expansions while enhancing the conductivity of the whole anode composite. As a result, Ni 2 P@N-C electrode delivers an ultrahigh capacity of 172.6 mAh g −1 at 2000 mA g −1 after long time of 3000 cycles and shows outstanding rate performance of 136.6 mAh g −1 at 5000 mA g −1 . Lastly, ex situ X-ray diffraction analysis of K + ion insertion/extraction into/from the Ni 2 P@N-C electrode shows that potassium ion storage mechanism was to be Ni 2 P + 3K + +3e - ↔K 3 P + 2Ni.

Earth-abundant nickel-based composites are of high concern as electrocatalysts for the oxygen evolution reaction (OER) which are significant to many sustainable chemical and energy transformation technologies. However, the realization of effective OER is still far away by the requirement of a high sustainable driving potential above thermodynamic requirements. In this work, we develop an innovative one-pot in-situ approach to synthesize nitrogen (N) and phosphorous (P) co-doped carbon nanotubes (CNTs) embedded with Ni 2 P nanoparticles. The structure of Ni 2 P nanoparticles in carbon nanotubes and their electrocatalytic activities have been studied in relation to varied carbonization temperatures. Benefiting from the in-situ designed Ni 2 P nanoparticles, N, P co-doped carbon nanotubes (NP-CNTs) with larger surface area, pore-rich structure, and optimized temperature, the as-prepared Ni 2 P NPs/NP-CNT-850 exhibits remarkable electrocatalytic activity for the OER in 1.0 M alkaline solution. In particular, the optimized Ni 2 P NPs/NP-CNT-850 can achieve a reference current density of 10 mA cm −2 at a very low overpotential of 298 mV and lower Tafel slope of 53 mV dec -1 . This electrocatalyst also shows long-term stability without significant degradation for 17 h. Our study opens innovative in-situ engineering to dramatically increase the electrocatalytic activity of Ni-based composite for other applications via rational design of architectures with multiple active sites.

Design and synthesis of non-noble electrocatalyst with controlled structure and composition for hydrogen evolution reaction (HER) are significant for large-scale water electrolysis. Here, an elegant multi-step templating strategy is developed for the fabrication of vertically aligned CoP@Ni2P nanowire–nanosheet architecture on Ni foam. Cobalt–carbonate hydroxides nanowires grown on Ni foam are first synthesized as the self-template. Afterward, a layer of amorphous Ni(OH)2 nanosheets is grown on the Co-based precursors through a chemical bath process, which is then transformed into the hierarchical CoP@Ni2P nanoarrays by a co-phosphatization treatment. Owing to the synergistic effect of the compositions and the advantages of the hierarchical heterostructures, the resulting hybrid electrocatalyst with dense heterointerfaces is revealed as an excellent HER catalyst, with a low overpotential of 101 mV at the current density of 10 mA cm−2, a relatively small Tafel slope of 79 mV dec−1, and favorable long-term stability of at least 20 h in 1 M KOH.

Electrocatalytic two-electron oxygen reduction reaction (2e − ORR) is considered one of the most promising approaches to replace the traditional anthraquinone method for hydrogen peroxide synthesis. Developing advanced electrocatalysts with excellent two-electron activity and selectivity remains challenging. In this study, an interfacial engineering regulation strategy is proposed to construct crystalline-amorphous heterogeneous catalysts by introducing crystalline Ni 2 P via in-situ phosphorization of NiMoO 4 nanorods. This structure not only exposes abundant catalytic active sites but also effectively enhances the overall conductivity of the catalyst. The novel Ni 2 P-NiMoO x exhibits remarkable 2e − ORR performance, with the H 2 O 2 selectivity exceeding 92 % over a wide voltage range. Remarkably, a high H 2 O 2 production rate (4009 mmol g −1 h −1 ) is achieved by Ni 2 P/NiMoO x in H-cell test, which is 3.1 times higher than that of NiMoO 4 and 1.5 times greater than that of Ni 2 P. This study indicates the significant potential of crystalline-amorphous heterojunctions to improve the performance of 2e − ORR electrocatalysts.

During the photocatalytic production of hydrogen gas, close interface with a catalyst is very important. We designed a noble-metal-free photocatalytic system that is spatially separated to produce hydrogen by high frequency visible light. We used a new type of a catalyst consisting of hollow core-shell CdS@TiO 2 /Ni 2 P structures prepared using sacrificial template method. Photocatalytic decomposition of water was tested using this catalyst. Hydrogen production yield using 420 nm light was 14.80 mmol/g after 2.5 h and using Xe lamp with AM1.5G filter was 34.78 mmol/g after 2.5 h. Hollow core shell CdS@TiO 2 /Ni 2 P particles were more stable than hollow core shell CdS@TiO 2 /Pt structures because TiO 2 protected CdS from photo-corrosion. Combination of CdS and Ni 2 P increased absorption range of TiO 2 at 720 nm. Holes and electrons produced during the photo-reaction can migrate to the CdS on the inside and to the Ni 2 P on the outside of the TiO 2 protective coating. Such design exposes more surface, thus, increases hydrogen production.

The design of multi-components nanostructure with interface heterojunction is the cutting-edge research in recent years because the catalytic activity , stability, and durability of catalysts are highly affected by the strong electronic effects, geometric effects, and synergistic effects occurring at the interface. Based on this, an efficient bifunctional electrocatalyst embedding highly dispersed Ni 2 P/Co nano heterojunction at the porous hollow-out carbon shell is developed for overall water splitting through evenly epitaxial growth of ultrathin Ni 2 P nanosheets on Co-based ZIF-67. The distinct electron interaction between the interfacial Ni 2 P (300) and Co (100) effectively lowers the overpotential of OER (316 mV vs. RHE) and HER (149 mV vs. RHE) at the current density of 10 mA cm −2 . Density functional theory (DFT) calculation further identifies that the Ni 2 P and Co heterojunctions optimize the adsorption energy of intermediate products and lower the energy barrier of the rate-determining step of OER significantly. This work provides a rational design of a well-defined interface toward overall water splitting electrocatalysts and offers a scientific basis for an in-depth understanding of the mechanism of the catalysts with nano heterojunction.

Graphical Bifunctional catalyst, cubed : Nanocuboid Ni 2 P has been synthesized through a facile colloidal method and further used as a bifunctional catalyst for efficient hydrogen generation from the hydrolysis of ammonia borane and electrocatalytic hydrogen evolution (see figure). The design of high-performance catalysts for hydrogen generation is highly desirable for the upcoming hydrogen economy. Herein, we report the colloidal synthesis of nanocuboid Ni 2 P by the thermal decomposition of nickel chloride hexahydrate (NiCl 2 ⋅ 6 H 2 O) and trioctylphosphine. The obtained nanocuboid Ni 2 P was characterized by using powder X-ray diffraction, transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and inductively coupled plasma atomic emission spectroscopy. For the first time, the as-synthesized nanocuboid Ni 2 P is used as a bifunctional catalyst for hydrogen generation from the hydrolysis of ammonia borane and electrocatalytic hydrogen evolution. Owing to the strong synergistic electronic effect between Ni and P, the as-synthesized Ni 2 P exhibits catalytic performance that is superior to its counterpart without P doping.

Electrocatalytic water splitting for hydrogen production plays a vital role in the development of new energy field, but there is still a lack of low-content precious metal or cost-effective non-noble metal catalysts for the hydrogen evolution reaction (HER). Therefore, how to develop the catalysts with a smaller amount of precious metal to achieve higher performance is still a major challenge. Herein, we have fabricated Ru–Ni 2 P@Ni(OH) 2 /NF-2 heterostructure by phosphating Ni(OH) 2 /NF and then anchoring Ru on the surface through wet chemical strategy. Benefiting from its optimal Δ G H∗ and synergistic effect , this Ru–Ni 2 P@Ni(OH) 2 /NF-2 catalyst shows superior electrocatalytic HER kinetics in alkaline electrolyte . A small overpotential of 31 mV is needed for this electrocatalyst to obtain the current densities of 10 mA cm −2 with remarkable durability over 24 h. This work provides a new strategy for the preparation of effective HER electrocatalyst with a low precious metal content.

Although the engineering of visible-light-driven photocatalysts with appropriate bandgap structures is beneficial for generating hydrogen (H2), the construction of heterojunctions and energy band matching are extremely challenging. In this study, In2O3@Ni2P (IO@NP) heterojunctions are attained by annealing MIL-68(In) and combining the resulting material with NP via a simple hydrothermal method. Visible-light photocatalysis experiments validate that the optimized IO@NP heterojunction exhibits a dramatically improved H2 release rate of 2485.5 μmol g–1 h–1 of 92.4 times higher than that of IO. Optical characterization reveals that the doping of IO with an NP component promotes the rapid separation of photo-induced carriers and enables the capture of visible light. Moreover, the interfacial effects of the IO@NP heterojunction and synergistic interaction between IO and NP that arises through their close contact mean that plentiful active centers are available to reactants. Notably, eosin Y (EY) acts as a sacrificial photosensitizer and has a significant effect on the rate of H2 generation under visible light irradiation, which is an aspect that needs further improvement. Overall, this study describes a feasible approach for synthesizing promising IO-based heterojunctions for use in practical photocatalysis.

Splitting water to produce hydrogen through an efficient and low-cost way requires the development of catalysts based on earth-abundant elements. Among transition metal phosphides, bimetal phosphides demonstrate superior hydrogen evolution reactivity to monometal phosphides. Therefore, we synthesized Ni2P–Co2P nanowire arrays on nickel foam with excellent catalytic performance by hydrothermal and low-temperature phosphorization. In 1 M KOH, the catalyst demonstrates low overpotentials of 99 and 161 mV to reach current densities of 10 and 100 mA cm–2, respectively. In 0.5 M H2SO4, the overpotentials of Ni2P–Co2P are only 94 and 159 mV at current densities of 10 and 100 mA cm–2, respectively. In a neutral solution, the overpotentials of the catalyst are also only 146 and 309 mV at current densities of 10 and 100 mA cm–2, respectively. The Tafel slopes of Ni2P–Co2P are only 53.1, 48.26, and 138.3 mV dec–1 in acid, alkaline, and neutral solutions, respectively. Moreover, the outperformance of its durability was tested for 20 h in acid and alkaline solutions, which maintained a stable current density of 10 mA cm–2. This work demonstrates a feasible route to design transition metal phosphides used in pH-universal HER electrocatalysts.
