“…Several of these metal phosphide syntheses employ a gas‐solid reaction, similar to the heat treatment step reported in this work, to produce a metal phosphide supported on a 3D metal structure . Control of phase composition remains limited in these cases, as the metal support is not fully converted into a metal phosphide.…”

“…Moreover, most 3D supports, such as nickel foams, are difficult to integrate into a microbattery due to their macroscopically large struts and pores. In some cases, phosphidation yields an interesting, textured, nanoscale morphology on the support surface . Such surface features are coincidental, however, and difficult to control synthetically.…”

“…28 Based in part on this prediction, we set out to evaluate all 7 structurally and stoichiometrically distinct Ni x P y phases that are stable below 800 C. Recently, Popczun et al 8 described the HER activity of Ni 2 P nanoparticles (NPs) predominantly expressing the [001] facet and conrmed the high activity of this material, although still less active than Pt. 28 Nanoparticulate Ni 5 P 4 has previously been shown to be an efficient anode material in lithium-ion batteries, 29,30 although its catalytic properties have not been reported.…”

“…Due to the wide range of unique magnetic, redox, and catalytic properties exhibited by transition metal phosphides, the development of methods for their production on the nanoscale with control of size, shape, and composition is an important endeavor. Because the magnetic and catalytic properties of transition metal phosphides depend on the size and shape (in the nano regime) as well as the composition, it is important to establish the synthetic factors that enable access to different phase-pure transition metal phosphides. Metal-rich nickel phosphides such as Ni 2 P are potent hydrotreating catalysts ,,,, while the more phosphorus-rich phases such as Ni 5 P 4 and NiP 2 are promising candidates for lithium ion battery electrode materials due to their high gravimetric and volumetric capacity. , Furthermore, all of these phases show considerable potential to be used in hydrogen evolution catalysis. …”
