Transition metal hydroxides have the advantage of high activity and low cost in alkaline electrolytes and are considered one of the most promising catalysts for anodic oxygen evolution reaction (OER). However, single nickel or iron hydroxides is unstable during the reaction process and have a tendency to agglomerate and poor electrical conductivity. Therefore, we designed a kinetically controlled liquid-phase method to synthesize scalable low-crystalline gamma-FeOOH@Ni(OH)(2) nanosheet arrays on nickle foam (NF) in an open environment. By adjusting the alkalinity and reaction time, we systemat...
