dc.description.abstract | The dissolution of Ir-oxide-based catalysts remains a roadblock in the development of durable electrocatalytic oxygen evolution reaction (OER) catalysts. Both the activity and stability of Ir-based catalysts are critically dependent on the ratio of stable rutile IrO2 and unstable amorphous Ir oxide (a-IrOx), as well as the spatial relationship between them. Here, we report that the domain size in hollow ternary Ir alloy nanocages can be fine-tuned by the introduction of dopant elements during the growth of parent core-shell nanoparticles, Cu@Culr After electrochemical oxidation under OER conditions, Ir alloy nanocages possessing multiple crystallites in their structure are transformed into hollow aggregates of loosely knit crystalline IrO2@a-IrOx domains, whereas single-crystalline Ir alloy nanocages are transformed to hollow Ir oxides with a random mixture of a-IrOx and IrO2. The loosely knit IrO2@a-IrOx structure achieves high OER activity and long-term stability, which is not feasible with the random mixture of a-IrOx and IrO2. | - |
