Abstract

A nano Ir_xMn_(1−x)O_y hybrid electrode with a L1₂-IrMn₃ phase was used as a bifunctional catalyst with ultra-low iridium loading for overall water electrolysis in an acid solution for the first time. The HER activity of the Ir_xMn_(1−x)O_y hybrid electrode not only exceeded that of IrO₂, but also exceeded that of Pt/C. The OER activity of the Ir_xMn_(1−x)O_y hybrid electrode also exceeded that of IrO₂.
