a Cu K-edge and b Zn K-edge XANES spectra for Cu/ZnO/Al2O3, CuZn/SiO2 and CuZn/Al2O3 catalysts in their initial state (dashed lines), and under operando conditions in CO2+CO+H2, p = 20 bar, T = 220 °C (solid lines). The reference spectra for CuO and ZnO (dashed lines), Cu and Zn foils (solid lines) are also shown. The vertical arrow in b marks the signature of the zinc spinel structure.
