“…It shows two characteristics redox couples of Ir(III)/Ir(IV) and Ir(IV)/Ir(V) transitions, which can be observed at -0.016 V and 0.316 V (vs Ag|AgCl), respectively. Nevertheless, these values were slightly higher than those reported by Petit & Plichon (1998), which were found to be at -0.175 V and 0.205 V (vs Ag|AgCl) (Petit & Plichon, 1998). This positive potential peak shift is mainly due to the electrodeposition solution being in basic medium (Khalil et al, 2016).…”

This work reports an investigation into the synthesis and electrodeposition of iridium oxide nanoparticles to fabricate an Au-based super-Nernstian potentiometric pH sensor. Monodisperse ultrafine iridium oxide nanoparticles with a mean particle diameter of 1-2 nm were successfully synthesized by the facile alkaline hydrolysis method and electrodeposited on the surface of Au substrate using Cyclic Voltammetry (CV). Based on the result, it was observed that the iridium oxide deposited Au substrate had a rough surface morphology. It was also found that the as-prepared sensor exhibited an excellent pH sensitivity and good stability over a long period, with a super-Nernstian response value of -73.7 mV/pH.

“…The IrOx deposition solution 16 16,23 The latter was chosen because of our experience in the templated electrodeposition of nanostructured materials. [24][25][26][27][28] Templated electrodeposition has proved to be an excellent means to tune the properties of materials by modifying their structure rather than their 75 elemental composition.…”

Electrodeposition of highly ordered macroporous iridium oxide through self-assembled colloidal templates

et al. 2009

Iridium oxide electrodeposited through a self-assembled colloidal template has an inverse opal structure. Monolayers present long range hexagonal arrangements of hemispherical nanocavities while multilayers present 3D honeycomb structures with spherical voids. The films are amorphous, 10 have several electroactive redox states and are electrochromic. The nanostructure modifies their reflectivity thus indicating these films could be used as tunable photonic devices.

“…The standard potential of transformation of the oxide from Ir 2 O 3 to IrO 2 is reported to take place at 0.926 V RHE [46], whereas redox reaction at 1.35 V RHE is reported to take place together with the onset of O 2 [33]. The Ir(V) state has also been observed, however, only in basic media [47]. Corrosion on IrO 2 take place according to reaction 2.53 in parallel with evolution of O 2 [33].…”
