Figure 3.8 Charge of bulk peak (blue line) and UPD peak (pink line) vs. pH on
oxidized ruthenium electrode in 2mM CuSO4 and 0.5M K2SO4 as
electrolyte; pH is adjusted by H2SO4 and NaOH; Scanrate =
20mV/s.
3.4 Effect of different oxidized potential on ruthenium electrode
Oxidized potential on ruthenium electrode is one of critical aspects to
investigate the behavior of oxidized ruthenium electrode, which also help to
distinguish the oxidized ruthenium and ruthenium electrodes. [5-8]
From the figure 3.9, the capacity of oxidized ruthenium electrode is
increasing, as the oxidized potential is higher. As the oxidized potential
increases, the bulk peak will shift to negative; the monolayer of UPD peak
becomes clear, the monolayer of UPD peak also becomes more; the distance
between the bulk peak and UPD peak is increasing, it means that the copper
deposition becomes easier and the under potential deposition happens at the
more positive potential by comparing the bare ruthenium electrode from table45
