Nanostructured Ni oxide electrocatalyst modified with Fe to enhance oxygen evolutionreaction

In this research, we synthesized an effective NiFeOxHy electrocatalyst by a two-step procedure of hydrothermaland calcination on the Ni foam (NF) substrate. The NiFeOxHy/NF electrode exhibited remarkable oxygenevolution reaction (OER) activity with a small value of the Tafel slope and a low overpotential in ۱.۰ M KOH.
