With excellent oxygen evolution reaction (OER) activity and stability in acidic media, IrOx-based materials are regarded as the most suitable catalysts to fulfil the technological requirements in acidic conditions. However, because of the high cost of Iridium, it is crucial to reduce the Ir consumption without compromising catalytic activity[1-3].
In this study, we synthesized a novel IrOx-based composite catalyst by low temperature processes, and the obtained catalyst showed an outstanding OER performance in acidic media. The detail synthesis method, micromorphology and performance of the catalyst will be presented at the meeting.
