Fig. 4: Association between curves of production concentrations and voltammogram at different pH during electrochemical oxidation of ethanol.

From: Relationship between oxide identity and electrocatalytic activity of platinum for ethanol electrooxidation in perchlorate acidic solution

Fig. 4

pH = 0.32 (0.1 M ethanol at 0.5 M HClO4), pH = 3.92 (0.4999 M NaClO4 + 0.0001 M HClO4), and pH = 6.16 (0.5 M NaClO4). The red square (■) and blue dot (●) represent concentrations of acetaldehyde and acetic acid, respectively, determined by HPLC. The black curves stand for voltammetry profiles.
