echemdb identifier: meng_2012_the_5222_f1_red_1
tags: BCV

A cyclic voltammogramm for Au(poly) recorded in \(\ce{ EMIM-TFSI }\) at a scan rate of \(400 \; \mathrm{mV\,s^{-1}}\) from Figure 1 in Y. Meng et al. The hydrogen evolution reaction in a room temperature ionic liquid: mechanism and electrocatalyst trends. Physical Chemistry Chemical Physics, 14\(15\):5222–5228, 2012.

Further information

The figure shows digitized data.

Preparation procedure not available.

Comment left by the curator on the published figure Parts of the curve are hardly visible. Also the units on the y-axis are given in uA / cm2 / M which is currently not supported by the echemdb module of unitpackage, nor is M a supported unit by astropy. See also issue unitpackage/issues/112.
