A novel bifunctional catalyst for overall water electrolysis: nano IrMnO hybrids with L1-IrMn phase
A nano Ir x Mn (1− x ) O y hybrid electrode with a L1 2 -IrMn 3 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 x Mn (1− x ) O y hybrid electrode not only exceeded that of IrO 2...
