Pd(111) - \(0.1 \; \mathrm{M}\) \(\ce{ HClO4 }\)

echemdb identifier: hara_2007_preparation_5733_f6a_solid
tags: BCV

A cyclic voltammogramm for Pd(111) recorded in \(0.1 \; \mathrm{M}\) \(\ce{ HClO4 }\) at a scan rate of \(10 \; \mathrm{mV\,s^{-1}}\) from Figure 6a in M. Hara et al. Preparation and electrochemical characterization of palladium single crystal electrodes in 0.1 M H2SO4 and HClO4: Part I. Low-index phases. Electrochimica Acta, 52\(18\):5733–5748, 2007.

Further information

The figure shows digitized data.

The Pd(111) electrode was prepared by:

• Pd wire etched in aqua regia, rinsed with Milli-Q water and dried.
• Forming of liquid bead by using an electron beam in a vacuum chamber.
• 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.
