Peapod-Like Structured B/N Co-Doped Carbon Nanotube Array Encapsulating MxPy (M = Fe, Co, and Ni) Nanoparticles for High-Rate Potassium Storage

“…The strong peak at 133.4 eV is related to the P–C bond, which is conducive to CoP/Co 2 P NP fixation in a tubular structure, avoiding the self-agglomeration during the intercalation/deintercalation of potassium ions. The peak at 134.5 eV can be assigned to oxidized P species caused by unavoidable exposure in the air . In addition, the high-resolution XPS spectrum of C 1s is shown in Figure g, where an intense peak locates at 284.7 eV, corresponding to graphite-C (sp 2 hybridization state).…”

“…The peak at 134.5 eV can be assigned to oxidized P species caused by unavoidable exposure in the air. 30 In addition, the highresolution XPS spectrum of C 1s is shown in Figure 3g, where an intense peak locates at 284.7 eV, corresponding to graphite-C (sp 2 hybridization state). Two smaller peaks at 285.7 and 286.9 eV are pertinent on C−N and C−P bonds, respectively.…”

Hollow Structured Transition Metal Phosphates and Their Applications

“…Similarly, for ORR the halfwave potential of 0.860 V or higher was obtained which was 36 mV higher as compared to Pt/C. [111] Heteroatom doped NiP showed greater enhancement towards catalytic activity for HER due to an increase in density of reactive sites as well as regulating the adsorption/desorption capacity of reacting intermediate. [112] Co(PO 3 ) 2 /MoO 4 /rGO metal phosphate was synthesized by anion exchange and phosphating process which was used as a catalyst for water splitting at 1.0 M KOH solution.…”

“…The result showed the highest stability towards HER and OER at an overpotential of 125 mV and 273 mV at a current density of 10 mA cm −2 . Similarly, for ORR the half‐wave potential of 0.860 V or higher was obtained which was 36 mV higher as compared to Pt/C [111] . Heteroatom doped NiP showed greater enhancement towards catalytic activity for HER due to an increase in density of reactive sites as well as regulating the adsorption/desorption capacity of reacting intermediate [112] …”

Electrospinning construction of a Fe–Ni-based multicomponent hybrid as synergistic electrocatalyst for water electrolysis

“…[61][62][63] Although massive studies have been made, more continued efforts are still needed to overcome low activities and low stabilities. [64][65][66] Inspired by the above analysis, in the present work, a series of Fe-Ni-based hybrids of phosphide/nitride/ alloy/N, P doped NCF were facilely prepared by electrospinning and the hybrids exhibited outstanding performance and stability on HER, OER, and water-splitting in alkaline conditions.…”
