Hierarchical iron–nickel oxyhydroxide nanosheets directly grown on porous TiFe2-based intermetallics for robust oxygen evolution

Abstract

Rationally designing highly active oxygen evolution reaction (OER) electrocatalysts with robust stability is critical for industrial electrochemical water splitting. Hierarchical iron–nickel oxyhydroxide nanosheets directly grown on porous TiFe2-based intermetallics are designed and prepared as OER catalysts. The best-performing nanosheets only need 295 mV to achieve 100 mA cm−2, along with exceptional durability at a high current density of 1000 mA cm−2. This work introduces a scalable strategy for producing robust OER catalysts that have potential for industrial applications.
