Abstract
None:
Pulsed-laser synthesis traps Ir in WO3, creating sub-nanometric IrWOx solid solutions with 42% of the Ir used in IrO2. The catalyst exhibits a mass activity of 270 A gIr-1 at 1.55 V and enables durable PEM water electrolysis. Strong Ir-W coupling optimizes the Ir oxidation state and boosts OER activity.
