Phase segregation reversibility in mixed-metal hydroxide water oxidation catalysts
Abstract
Achieving stable, low-cost electrocatalysts represents a daunting challenge towards practical water oxidation reactions. Here, we report that a degraded electrocatalyst can be revivified under catalytic operating conditions by manipulating reversible phase segregation. Under the oxygen evolution reaction conditions, Fe segregation develops in the Ni–Fe hydroxide host lattice, with the formation of FeOOH, resulting in an interface between the...
