Co(0001) - \(0.1 \; \mathrm{M}\) \(\ce{ NaOH }\)

echemdb identifier: foelske_2004_initial_10_f2a_solid
tags: BCV

A cyclic voltammogramm for Co(0001) recorded in \(0.1 \; \mathrm{M}\) \(\ce{ NaOH }\) at a scan rate of \(5 \; \mathrm{mV\,s^{-1}}\) from Figure 2a in A. Foelske et al. Initial stages of hydroxide formation and its reduction on Co\(0001\) studied by in situ STM and XPS in 0.1 M NaOH. Surface science, 554\(1\):10–24, 2004.

Further information

The figure shows digitized data.

The Co(0001) electrode was prepared by:

• Oriented by Laue diffraction, mechanically and chemically polished.
• Annealed at 653 K for 48 h in ultrapure hydrogen (6 N) at normal pressure (1 atm).
