Ir(111) - \(0.01 \; \mathrm{M}\) \(\ce{ NaF }\)

echemdb identifier: pajkossy_2005_voltammetry_69_f4a_solid
tags: BCV

A cyclic voltammogramm for Ir(111) recorded in \(0.01 \; \mathrm{M}\) \(\ce{ NaF }\) at a scan rate of \(50 \; \mathrm{mV\,s^{-1}}\) from Figure 4a in T. Pajkossy et al. Voltammetry and impedance measurements of Ir\(111\) electrodes in aqueous solutions. Journal of Electroanalytical Chemistry, 582\(1\-2\):69–75, 2005.

Further information

The figure shows digitized data.

The Ir(111) electrode was prepared by:

• High temperature annealing at about 1900°C in a nitrogen hydrogen atmosphere for 100s.
• Transferred to the electrochemical cell under 5N argon or in a 6N nitrogen stream.
• Hanging meniscus configuration.
