Abstract |
Breakthrough in the hydrogen economy requires highly active and durable electrolytic water splitting catalysts for efficient, eco-friendly production of hydrogen. Hollow structured nanoparticles paid enormous attention for their enhanced catalytic activity toward water splitting reaction due to their intrinsically high surface-to-volume ratio. Iridium(Ir)-based alloy catalysts are widely used as electrocatalysts for oxygen evolution reaction (OER), which is rate determining step for overall water splitting. We have previously reported that introduction of cobalt(Co) as a dopant to IrCu octahedral nanocrystal enabled the formation of ternary IrCu octahedral nanocages, which showed enhanced OER activity and durability under acidic condition. And we also found other first transition metal elements can play similar role like Co dopant, which directs the formation of ternary IrCu nanocages. Herein, the relations between the transition metal dopants and electrolytic OER performance will be presented. |
