Figure 8
FEXRAV results at the Cu L3 and K edges probing in situ the electrodeposition and dissolution mechanism of Cu in aq. 0.1 M CuSO4. The top panel presents the typical CV of the Pt | aq. 0.1 M CuSO4 electrochemical system. The FEXRAV signals at three different excitation energies are presented in the middle panel, while the corresponding first derivatives are depicted in the bottom panel. Vertical dashed lines are shown as indicators of the EWE at which the relevant electrochemical reactions discussed in the text take place. |
