Ir(100) - \(0.1 \; \mathrm{M}\) \(\ce{ HClO4 }\)

echemdb identifier: pajkossy_2007_voltammetry_113_f1a_solid
tags: BCV

A cyclic voltammogramm for Ir(100) recorded in \(0.1 \; \mathrm{M}\) \(\ce{ HClO4 }\) at a scan rate of \(10 \; \mathrm{mV\,s^{-1}}\) from Figure 1a in T. Pajkossy et al. Voltammetry and impedance measurements of Ir\(100\) electrodes in aqueous solutions. Journal of Electroanalytical chemistry, 600\(1\):113–118, 2007.

Further information

The figure shows digitized data.

The Ir(100) electrode was prepared by:

• High temperature annealing at about 1900°C in a nitrogen-hydrogen atmosphere for 1 min.
• Cool down in the gas stream for 2 min.
• Transferred to the electrochemical cell under protecting gas stream.
• Hanging meniscus configuration.
