High crystallinity design of Ir-based catalysts drives catalytic reversibility for water electrolysis and fuel cells

Reversible multifunctionality in electrocatalysts can allow voltage reversal during device operation. Here, authors design a crystalline Ir-based electrocatalyst with a thin reversible metallic-Ir/IrOx layer that shows activity for O2 evolution, H2 evolution, and H2 oxidation.
