Fig. 3

Mass activity of state-of-the-art nano-sized IrO2, nano-sized Ir metal, nano-sized IrOxHy, E-Sr4IrO6-BM, and μm-sized HP-IrOxHy-BM catalysts. E-Sr4IrO6-BM is derived from Sr4IrO6-BM, which is electrochemically activated with CV scanning (Fig. S17). The error bars represent the standard deviation derived from three independent measurements.
