Figure 3. — Copper voltammetry performed in scCO₂ with 12.1 wt % CH₃CN and [NⁿBu][BF₄] (20 mM) at 310 K and 17.24 MPa. Electrodes were: 25 μm diameter platinum disc working electrode, 0.5 mm diameter platinum disc pseudo reference and 0.5 mm diameter platinum wire counter electrode. The sweep rate was 20 mV s⁻¹. The insert shows the limiting current as a function of the concentration of the copper complex. (Adapted from [44].)
