a, b In-situ Cu K-edge XANES spectra of YSZ/CuO (a) and ZrO2/CuO (b) at applied potentials. c XPS spectra of Cu LMM, showing comparison of Cu+/Cu0 composition ratios on spent YSZ/CuO, ZrO2/CuO and CuO. d, e Evolution of various Cu species fractions as a function of the applied potential for YSZ/CuO (d) and ZrO2/CuO (e). f, g In-situ WT k3-weighted EXAFS contour plots of YSZ/CuO (f) and ZrO2/CuO (g) at applied potentials.
