The anodic reaction of oxygen evolution reaction (OER), an important point for electrolysis, however, remains the obstacle due to its complicated reaction at electrochemical interfaces. Iridium oxide (IrO 2 ) is the only currently known 5d transition metal oxide possessing admirable OER activity. Tr...
