Prussian blue analog-derived nickel iron phosphide-reduced graphene oxide hybrid as an efficient catalyst for overall water electrolysis

Prussian blue analog‐derived bimetallic phosphide nanoparticles anchored in nitrogen‐doped porous electrospun carbon nanofibers for efficient oxygen evolution reaction

“…The weaker peak at 853.5 eV can be attributed to the Ni‐P bond in (NiFe) 2 P. For the Fe 2p spectrum in Figure 6f, the peaks at 707.3 and 713.4 eV belong to Fe 2p 3/2 , in which the peak at 707.3 eV can be attributed to the bond of Fe‐P and the peak at 713.4 eV corresponds to Fe‐PO x species due to the superficial oxidation. The peak at 726.0 eV of Fe 2p 1/2 and the peak at 713.4 eV of Fe 2p 3/2 both originate from the bond of Fe‐O at the surface of the sample 72 . There are two satellite peaks at 719.4 and 729.1 eV corresponding to Fe 2p 3/2 and Fe 2p 1/2 , respectively.…”

The existence of the bonds of Ni-P and Fe-P further demonstrates that Ni-Fe phosphides were generated after the phosphating process.…”

Interfacial charge transfer in sheet Ni2P–FePx heterojunction to promote the study of electrocatalytic oxygen evolution

“…13 Transition metal phosphide (TMP) has become an excellent electrocatalytic catalyst for water decomposition, thanks to its abundance and affordability. [14][15][16] But its electrocatalytic efficiency is still unsatisfactory. Therefore, the development of efficient and stable transition metal electrocatalysts for OER remains a challenge.…”

One-step fabrication of vanadium-doped CoFe PBA nanosheets for efficient oxygen evolution reaction

“…The adhesives are often with poor OER property. 25,26 The mixture will reduce the active sites and structural stability. According to the current study, there are two ways to improve PBAs as electrocatalysts: (i) altering the PBAs’ shape can expose more active sites and increase their specific surface area.…”
