Preparation of NiFeCoMnCr Hydroxide on Nickel Foam by Corrosion Method and its Enhanced Electrochemical Performance in Oxygen Evolution Reaction
Abstract
The corrosion method off ers a viable means to fabricate effi cient electrocatalysts for electrochemical reactions, ensuring
strong adhesion between the substrate and the formed material and minimizing resistance between the catalyst and the
electrode. This study introduces a method for synthesizing a high-performance oxygen evolution reaction (OER) catalyst by
cultivating a transition metal-based multimetallic hydroxide on Ni foam via corrosion. The hydroxide, comprising Ni, Fe,
Co, Mn, and Cr, uniformly coated the Ni foam, ensuring even distribution of each transition metal within the catalyst. The
resultant NiFeCoMnCr hydroxide catalyst demonstrated enhanced OER performance, evidenced by reduced overpotential
and improved stability, outperforming binary, ternary, and quaternary hydroxides.
