Figure 7
(a) Rietveld refinement output of a dataset collected during the early stages of the OCP segment of the fifth cycle (t = 320 min, Rwp = 2.56). The experimental data are shown as a blue solid line, the calculated pattern the red solid line, and the difference pattern the grey solid line below. The tick marks below the difference curve are the Bragg reflection markers for Pb (upper), β-PbO2 (middle) and PbSO4 (lower). (b) Overlay of datasets collected at the beginning of the first GALV segment (upper), and for the substrate and Kapton® film before the flow of electrolyte commenced (lower). The Pb reflections are labelled with their Miller indices. |
