FeCoNi‐based Alloy Coatings as Low Overpotential Electrocatalysts for Alkaline Water Electrolysis

Developing efficient, stable and low-cost electrocatalysts is a viable approach to solve the current energy crisis. It is found that increasing the surface area of the electrodes can effectively promote the electrocatalytic efficiency. Herein, the atmospheric plasma spraying (APS) technology was used to prepare FeCoNi-Ni
