Abstract
Earth-abundant 3d-orbital late transition metals are the most used and highly desired catalysts for the oxygen evolution reaction (OER) but are prone to quick oxidative dissolution, leading to poor durability. We first report that FeCoNiCu multielemental alloy nanoparticles (MEA NPs) can be stabilized with only 0.3 at. % Pd, a 4d-orbital element. Although pure Pd is known for extremely poor OER activity and durability, Pd-FeCoNiCu sustains 1000 h at 10 mA cm–2. In an accelerating durability test (ADT) at 100 mA cm–2, it exhibits a mere 8.9 mV increase over 25 h with a degradation rate of 0.356 mV h–1, which is 1/350th that of FeCoNiCu (125 mV h–1) and among the most stable OER catalysts reported so far.…
