Abstract
Urchin-like hierarchical IrO2 nanostructures, which are obtained by a surfactant-free, wet-chemical approach, show boosted OER performance in acid with an overpotential of 260 mV @10 mA cm-2geo under optimal pocessing conditions. The overpotential @10 mA cm-2geo can be kept below 285 mV for over 30 hours.
