Figure 3. (A) Ir deposition investigation on Au RDE in 3 mM K3IrCl6 and 0.5 M Na2SO4 from a pH 4 electrolyte. (B) LSV curve of Ir SED, depending on pH of electrolytes. (C) XPS-derived Ir thickness on Au-seeded Si wafer, accounting for varying electrolyte pH levels and deposition times. (D) Evident Au 4f and Ir 4f spectra and (E) characteristic CV features in 0.5 M H2SO4, modulated by the number of Ir deposition pulses. This figure is quoted with permission from Ahn et al.[48].
