A cyclic voltammogramm for Pt(111) recorded in \(0.1 \; \mathrm{M}\) \(\ce{ HClO4 }\) + \(0.001 \; \mathrm{M}\) \(\ce{ KClO4 }\) + \(1 \; \mathrm{M}\) \(\ce{ KCl }\) at a scan rate of \(20 \; \mathrm{mV\,s^{-1}}\) from Figure 1 in N. Li et al. Chronocoulometric studies of chloride adsorption at the Pt\(111\) electrode surface. Journal of Electroanalytical Chemistry, 491\(1\-2\):95–102, 2000.

Further information

The figure shows digitized data.

The Pt(111) electrode was prepared by:
* A Pt single crystal bead was cut along the (111) orientation.
* The electrode was annealed in a hydrogen+air flame.
* Cooled in a hydrogen atmosphere.
* Quenched with ultrapure water.

Comment left by the curator on the published figure The scan rate is not given in the publication. It was manually determined from the charge integration as 20 mV / s.
