A cyclic voltammogramm for Pt(111) recorded in HClO4 + KClO4 + 0.01 M KBr at a scan rate of 50.0 \(\mathrm{mV\,s^{-1}}\) from Figure 1b in G. A. Mello et al. Bromide Adsorption on Pt(111) over a Wide Range of pH: Cyclic Voltammetry and CO Displacement Experiments. The Journal of Physical Chemistry C, 122(32):18562–18569, 2018.
Further information
The figure shows digitized data.
Preparation procedure not available.
Comment left by the curator on the published figure “Working solutions of the pH-series with values lower than 3 were prepared by using HClO4 and KClO4. For pH values ranging from 3 to 9, phosphate buffer solutions were employed (Na2HPO4 and NaH2PO4). Alkaline solutions were prepared with NaOH and KClO4. The exact concentrations of these components are unkown.”
