One-step solid-state synthesis of NixPy @C nanocomposites for high-performance hybrid supercapacitor

Unraveling the Catalytic Graphitization Mechanism of Ni–P Electroless Plated Cokes via In Situ Analytical Approaches

“…In addition, the detailed XRD patterns for Ni–P-plated coke and thermally treated Ni–P-plated coke at 600 °C were obtained to verify the Ni x P y nanostructures, as shown in Figure S5. Based on the JCPDS card file data, it can be observed that the Ni–P-plated coke sample undergoes a transformation from nickel nanoparticles to hexagonal Ni 2 P phase at a thermal treatment temperature in the range of 600–800 °C. , Further increasing the thermal treatment temperature to above 900 °C promotes graphitization, leading to the disappearance of the Ni x P y nanostructures. These behaviors highlight the vital role played by nickel nanoparticles in enhancing the crystallinity of carbon structures through their interaction with amorphous carbon during thermal treatment.…”

Preparation of the Amorphous NiCoP Nanosheet Array on Carbon Cloth for High‐Performance Solid‐State Hybrid Supercapacitor

“…[29] For the P 2p orbit (Figure 3d), two peaks located at binding energies of 129.6 and 128.7 eV are assigned to P 2p1/2 and P 2p3/2, respectively, further confirming the formation of the metal (NiÀ P, CoÀ P) bond. [33] Moreover, the peak at 132.8 eV (PÀ O bond) is attributed to phosphate, [34] possibly due to the oxidation of phosphide. These results are consistent with the XRD analysis.…”

Solvent-induced structural regulation over Ni2P/CNT hybrids towards boosting the performance of supercapacitors

“…3c. [51][52][53][54][55][56][57] To further analyze the capacitance retentions of the electrodes, we calculated the specific capacitance values at different current densities. As distinctly observed in Fig.…”

“…22,23 From this perspective, an effective approach for the former is to regulate the morphology of Ni 2 P towards a high specific surface area for plentiful reaction sites; the strategy for the latter is to hybridize with carbon materials like carbon nanotubes (CNTs) that exhibit high conductivity and excellent structural stability. 24–27…”

“…22,23 From this perspective, an effective approach for the former is to regulate the morphology of Ni 2 P towards a high specific surface area for plentiful reaction sites; the strategy for the latter is to hybridize with carbon materials like carbon nanotubes (CNTs) that exhibit high conductivity and excellent structural stability. [24][25][26][27] According to the aforementioned analysis, we herein employed a synergetic optimization strategy, along with structure regulation and hybridizing with CNTs. Based on solventinduced assistance, we prepared composites of flower-like and rod-like Ni 2 P threaded with CNTs via a template construction route, and evaluated their energy storage properties for supercapacitors.…”
