Facile fabrication of a binary NiCo phosphide with hierarchical architecture for efficient hydrogen evolution reactions

Amphoteric Membrane Loaded with a Noble Metal-Free Hollow Spherical NiCoP@rGO Bifunctional Electrocatalyst for Alkaline Water Electrolyzers

“…The results were in good agreement with the previous literature. 33,34 The peaks at 130.71 and 129.70 eV in the P 2p spectrum correspond to P2 1/2 and P2 3/2 of (P δ− ) in the form of metal phosphide, respectively (Figure 4d). The broad peak at 134 eV was attributed to the phosphate species that was formed due to superficial passivation of phosphide particles on the surface.…”

An efficient and recyclable Ni2P–Co2P/ZrO2/C nanofiber photocatalyst for the conversion of plastic waste into H2 and valuable chemicals

“…5(f), and the peak at 856.5 eV is assigned to Ni 2p 3/2 , while the peak at 861.9 eV belongs to the satellite of the Ni 2p 3/2 peak. 47 The peak at 873.6 eV could be attributed to the Ni 2p 1/2 spin–orbital splitting of Ni 2+ . 48 All the above characteristics confirm the successful conversion of Ni–Co precursors to Ni 2 P–Co 2 P on ZrO 2 /C NFs.…”

Sacrificial template synthesis of hollow-structured NiCoP microcubes as novel electrode materials for asymmetric supercapacitors

“…The signals at around 853.4 and 870.6 eV are associated with Ni δ+ , while the characteristic peaks located at 856.4 and 874.4 eV correspond to the Ni 2+ species. 51,52 In addition, the peaks at 880.6 and 861.9 eV are the satellite peaks. In the Co 2p spectrum (Fig.…”
