Pt(POSC) - \(0.1 \; \mathrm{M}\) \(\ce{ H2SO4 }\)

echemdb identifier: feng_2017_new_1003_f9_solid
tags: BCV

A cyclic voltammogramm for Pt(POSC) recorded in \(0.1 \; \mathrm{M}\) \(\ce{ H2SO4 }\) at a scan rate of \(10 \; \mathrm{V\,s^{-1}}\) from Figure 9 in Z. Feng et al. New advances in ohmic microscopy. Russian Journal of Electrochemistry, 53:1003–1010, 2017.

Further information

The figure shows digitized data.

The Pt(POSC) electrode was prepared by:

• POSC prepared by melting the tip of the wire using a hydrogen flame.
• Annealed in a methane flame continuously for 24 to 48 h.

Comment left by the curator on the published figure The E-axis was possibly erroneously denoted as SHE instead of RHE.
