“…Figure 4a shows the linear sweep voltammetry (LSV) curveso fc uboid Ni 2 P/C, spherical Ni 2 P/C, Ni/C, and commercial Pt/C (20 wt %) versus the RHE scale. It can be seen that Pt/C exhibitst he highest catalytic activity, with an overpotential of 22 mV to afford ac urrentd ensity of 10 mA cm À2 .H owever,s pherical Ni 2 P/C and Ni/C required 187 and 397 mV to reach 10 mA cm À2 ,r espectively.A se xpected, Ni 2 P/C exhibits high activity with an overpotential of 138 mV to achieve 10 mA cm À2 ,which is superior to most of the reported NiP-based catalysts, such as Ni 2 Pn anoparticles/graphene (h 10 mA cm À2 = 264 mV), [47] Ni 2 Pn anoparticles/Ti( h 10 mA cm À2 = 130 mV), [41] Ni 12 P 5 /CNT (h 10 mA cm À2 = 240 mV), [48] and monodisperse Ni 12 P 5 nanoparticles/GCE (h 10 mA cm À2 = 208 mV).

“…To facilitate HER application, it is urgent to develop low-cost alternatives with Earth-abundant and cost-effective features to replace the noble metals [17,18]. Thus, various non-noble materials including transition metal sulfides [19], selenides [20], oxides [21], carbides [22], and nitrides [23],…”

“…Pt-based electrodes.M oS 2 -based composite materials such as multi-walled carbon nanotubes (CNTs)-Cu-MoS 2 , [4] three-dimensional MoS 2 /reduced graphene oxide, [5] Cu-MoS 2 /reduced graphene oxide, [6] CoP/MoS 2 -CNTs hybrid catalyst, [7] and the metal-organic framework (MOF)-derivede lectrocatalysts Mo-N/C@MoS 2 , [8] represent improved electrode materials for cost-effective HER.Ar obusth ydrogen-evolution catalyst was revealed in ac arbon-supported, non-noble metal catalyst based on high-index (222)-faceted Ta Cn anocrystals (TaC NCs@C). [9] Tr ansitionm etal phosphides (TMPs) such as CoP, [7,10,11] MoP, [12] Ni 2 P, [13] Ni 12 P 5 , [14,15] and FeP, [16] in combinationw ith different carbon materials (carbon nanosheets, CNTs,g raphene carbono xides,o rn itrogen-dopedr educed graphene oxide) are considered to be effective electrocatalysts due to the extraordinary high conductivity and enhanced electrocatalytic HER performance.R ecently,i tw as discovered that solid structures designed from monodispersed metal phosphides( M x P y )e xhibit superior catalytic activity due to the higher positivec harge of the metal and stronger ensemble effect of Pi nM x P y structures. [17,18] TMPs can be regarded as crystall atticeso ft ransition metals doped with P. Until now, it has been determined that only six different transition metals (Fe, Co,N i, Cu, Mo,a nd W) form efficient TMPs for HER.…”
