Distorted octahedral sites drive early formation and stabilisation of nickel oxyhydroxides in trimetallic nickel–iron–molybdenum oxides
Trimetallic nickel–iron–molybdenum oxides are excellent electrocatalysts for alkaline water electrolysis despite experiencing severe molybdenum dissolution. While the impact of molybdenum on fresh samples is well-understood, its substantial loss during operation without compromising performance presents a unique puzzle. Here, we show that the initial presence of molybdenum induces the formation of
