Fe K-edge and Cu K-edge XAS monitoring of the reductive activation of the FeCu catalyst carried out by heating the catalyst from 25 to 400°C followed by one hour of isothermal heating at 400°C. Panels (a) and (c) show quick-EXAFS (1176 spectra, each being the average of ten spectra measured at the acquisition rate of 250 ms). Panels (b) and (d) show FF hyperspectral XAS imaging (300 spectra averaged over all the pixels of the catalyst bed and recorded each in 5.56 s).
