Two-dimensional amorphous iridium cobalt oxide for acidic oxygen evolution reaction

Chemical Communications, Год журнала: 2024, Номер unknown

Опубликована: Дек. 23, 2024

A two-dimensional amorphous iridium–cobalt oxide (Am-IrCo 5 O x ) was prepared, which exhibits a low overpotential of 230 mV at 10 mA cm −2 in 0.5 M H 2 SO 4 . DFT calculations show that the unsaturated Ir on surface acts as an active site.
