Abstract The pursuit of efficient and durable bifunctional electrocatalysts for overall water splitting in acidic media is highly desirable, albeit challenging. SrIrO 3 based perovskites are electrochemically active oxygen evolution reaction (OER), however, their inert activities toward hydrogen (HER) severely restrict the practical implementation splitting. Herein, an Ir@SrIrO heterojunction newly developed by a partial exsolution approach, ensuring strong metal‐support interaction OER HER....
Strontium iridate perovskites are alternative electrocatalysts for oxygen evolution reaction (OER) in acidic media. Nevertheless, their practical feasibility is still hindered by structural stability due to the inevitable Sr leaching during long-term electrocatalysis. Herein, we propose a 0D/2D heterostructure involving CeO2 quantum dots decorated SrIrO3 nanosheets achieve durable and active OER harsh environment. Theoretical calculations unveil that coupling with electronic rearrangement...
