“…The morphology and structure of the as-prepared samples were observed by transmission electron microscopy (TEM). [43][44][45] The Ni oxide was present as a thin layer on the nanoparticles which formed upon exposure of the nanoparticles to air contact. 2a clearly shows that the as-prepared pure Ni 2 P sample is composed of many particles with diameters of several dozen nanometers.…”

Ni 2 P nanoparticles grown on reduced graphene oxide (rGO) were successfully synthesized via the lowtemperature solid state reaction method and investigated as electrochemical pseudocapacitor materials for potential energy storage applications. The specific capacitance of the as-prepared Ni 2 P/rGO is 2266 F g 21 and the Ni 2 P/rGO composite also exhibits superior cycling performance when they are used as the capacitor materials. The as-prepared Ni 2 P/rGO sample demonstrates interesting supercapacitive properties with high capacitance and good cycling performance.

Phosphorous-rich FeP 2 /C nanohybrids are synthesized via the pyrolysis of ferrocene (Fe(C 5 H 5 ) 2 ) and red phosphorus in an evacuated and sealed quartz tube at 500 C. The nanohybrids contain orthorhombic FeP 2 with conical carbon tubes. Based on the calculated electroactive surface area, the performance of the FeP 2 /C nanohybrids as a novel non-noble metal electrocatalyst for hydrogen evolution reaction (HER) in 0.50 M H 2 SO 4 is investigated. These nanohybrids show good catalytic activity and stability in the acidic medium and might serve as a promising new class of non-noble metal catalysts for practical HER. Results and discussionRecently, we synthesized uniform Fe 2 P@C and FeP@C nanocables via the reaction of ferrocene (Fe(C 5 H 5 ) 2 ) with

“…Figure 3 a shows the high‐resolution Ni 2p XPS spectrum of the Ni 2 P sample, in which the binding energy for Ni 2p 3/2 and 2p 1/2 are observed at 857.68 eV and 875.68 eV, respectively, yielding characteristics of the Ni 2+ state 41. 42 The corresponding P 2p spectrum is shown in Figure 3 b, in which the P 2p 3/2 peak located at 134.88 eV indicates the existence of the oxidized state of phosphorus. For the Ni 5 P 4 sample, the peaks at 857.28 eV and 875.58 eV are assigned to the Ni 2p 3/2 and 2p 1/2 of the Ni 2+ state, and the peak at 853.78 eV is assigned to Ni 2p 3/2 of the elemental Ni state (Figure 3 c).…”

Herein, we describe a simple two-step approach to prepare nickel phosphide with different phases, such as Ni2 P and Ni5 P4 , to explain the influence of material microstructure and electrical conductivity on electrochemical performance. In this approach, we first prepared a Ni-P precursor through a ball milling process, then controlled the synthesis of either Ni2 P or Ni5 P4 by the annealing method. The as-prepared Ni2 P and Ni5 P4 are investigated as supercapacitor electrode materials for potential energy storage applications. The Ni2 P exhibits a high specific capacitance of 843.25 F g(-1) , whereas the specific capacitance of Ni5 P4 is 801.5 F g(-1) . Ni2 P possesses better cycle stability and rate capability than Ni5 P4 . In addition, the Fe2 O3 //Ni2 P supercapacitor displays a high energy density of 35.5 Wh kg(-1) at a power density of 400 W kg(-1) and long cycle stability with a specific capacitance retention rate of 96 % after 1000 cycles, whereas the Fe2 O3 //Ni5 P4 supercapacitor exhibits a high energy density of 29.8 Wh kg(-1) at a power density of 400 W kg(-1) and a specific capacitance retention rate of 86 % after 1000 cycles.
