“…Besides nanoparticles and nanocrystals, some other nickel phosphide nanostructures have also been successfully fabricated through the solution phase method for electrocatalytic HER, and the structure-dependent catalytic performance was also studied. For example, Li et al synthesized nanostructured Ni 2 P with different morphologies (nanorods and nanoparticles) by a one-step solution phase route in which the mixture of TOPO and TOP was used as solvent, but their electrocatalytic HER performances were not fully compared [54]. Pan et al synthesized nickel phosphide (Ni 2 P) nanoparticles (NPs) with different sizes through thermal decomposition of bis(triphenylphosphine) nickel dichloride (BTND) single source precursor in the presence of oleylamine by controlling the reaction temperature, and the Ni 2 P NPs with a small size exhibit higher electrocatalytic activity due to the larger electrochemical active surface area and higher conductivity [55].…”

The production of hydrogen through electrochemical water splitting driven by clean energy becomes a sustainable route for utilization of hydrogen energy, while an efficient hydrogen evolution reaction (HER) electrocatalyst is required to achieve a high energy conversion efficiency. Nickel phosphides have been widely explored for electrocatalytic HER due to their unique electronic properties, efficient electrocatalytic performance, and a superior anti-corrosion feature. However, the HER activities of nickel phosphide electrocatalysts are still low for practical applications in electrolyzers, and further studies are necessary. Therefore, at the current stage, a specific comprehensive review is necessary to focus on the progresses of the nickel phosphide electrocatalysts. This review focuses on the developments of preparation approaches of nickel phosphides for HER, including a mechanism of HER, properties of nickel phosphides, and preparation and electrocatalytic HER performances of nickel phosphides. The progresses of the preparation and HER activities of the nickel phosphide electrocatalysts are mainly discussed by classification of the preparation method. The comparative surveys of their HER activities are made in terms of experimental metrics of overpotential at a certain current density and Tafel slope together with the preparation method. The remaining challenges and perspectives of the future development of nickel phosphide electrocatalysts for HER are also proposed.

“…Ni x P y nanocatalysts are highly efficient at driving an overpotential of 1.57 V at 10 mA cm −2 in 1.0 M KOH for OER ( Li et al, 2016b ). Ni 2 P nanoparticles exhibit an overpotential of 0.2 V at 10 mA cm −2 in 0.1 M KOH for HER ( Li et al, 2015 ). It is reported that another kind of Ni 2 P nanoparticle delivers an overpotential of 290 mV at 10 mA cm −2 in 1 M KOH ( Stern et al, 2015 ).…”

The Ni2P nanowires were simply synthesized via a rapid one-step hydrothermal approach, in which deionized water, red phosphorus, nickel acetate, and hexadecyl trimethyl ammonium bromide were used as the solvent, phosphor and nickel sources, and active agent, respectively. The as-synthesized Ni2P nanowire clusters were composed of uniform nanowires with length of about 10 μm and diameter of about 40 nm. The Ni2P nanowires exhibited enhanced electrocatalytic activity for both hydrogen evolution reaction and oxygen evolution reaction This work provides good guidance for the rational design of nickel phosphides with unique nanostructures for highly efficient overall water splitting.

“…[6,7,49] However, as electrochemical performance of catalysts is directly related to their electrical conductivity, the intrinsic low conductivity of phosphate catalysts is found to be the key limitation that seriously diminishes their catalytic potency and restricts their practical application. [51][52][53][54][55][56][57] More recently, a TMP with a combination of cobalt and phosphorous due to its high electrical conductivity and unique structural, physical, and chemical properties has also shown promising ORR activity in alkaline medium. Due to their high electrical conductivity, unique structural features, and the merits of low cost, TMPs are promising candidates for catalytic applications.…”

Motivated by the challenge to find a low-cost catalyst with high activity for the oxygen reduction reaction (ORR), transition metal phosphides (TMPs) appear to be one of the most burgeoning alternatives to noble metal based electrocatalysts. In addition to the low cost, TMPs have numerous interesting features such as high conductivity and chemical stability. Since, the catalytic activity of TMPs is highly dependent on the metal/phosphorous ratio, herein, we report the investigation of nickel-phosphide/ carbon composites of different stoichiometries (Ni x P y /C) with tractable nickel phosphide phases as promising electrocatalyst for ORR under alkaline and acidic conditions. The Ni x P y /C composites are obtained by carbonization of a Ni-struvite (NiNH 4 PO 4 · H 2 O) coated phenol-formaldehyde resin at different temperatures, resulting in variations of the formed Ni x P y phases. As expected, it is found that the electrocatalytic ORR performance of the Ni x P y /C composites highly depends on the predominant phase of nickel phosphide formed. The highest catalytic activity for ORR in alkaline as well as acidic media was found for the Ni x P y /C composite with the highest proportion of Ni 2 P as a predominant phase, obtained at 800 8C. For composites with NiP 2 and Ni 12 P 5 as the predominant phase, obtained at lower and higher temperatures, respectively, a lower catalytic activity was found.
