Cu(111) - \(0.005 \; \mathrm{M}\) \(\ce{ H2SO4 }\)

echemdb identifier: broekmann_1999_in-situ_307_f1_solid
tags: BCV

A cyclic voltammogramm for Cu(111) recorded in \(0.005 \; \mathrm{M}\) \(\ce{ H2SO4 }\) at a scan rate of \(10 \; \mathrm{mV\,s^{-1}}\) from Figure 1 in P. Broekmann et al. In-situ STM investigation of specific anion adsorption on Cu\(111\). Journal of Electroanalytical Chemistry, 467\(1\-2\):307–324, 1999.

Further information

The figure shows digitized data.

The Cu(111) electrode was prepared by:

• Made out of single crystal rod.
• Oriented with Laue backscattering.
• Polished mechanically with diamond paste with different grain sizes down to 25 μm.
• Electropolished to remove copper oxide (details see https://doi.org/10.1016/S0022-0728(99)00463-5).
• Polishing of the bead to achieve the desired surface orientation.
• Inductive annealed for 6h at 900 °C in 5N argon.
• 15 min inductive annealing before each measurement.
• details see https://doi.org/10.1016/j.electacta.2006.11.048.
