Ex situ OER and ORR at different times scales: a schematic of effect of multilevel disorder engineering; b laser Raman microspectra; c normalized Mn-K, Ni-K, Co-K, and Fe-K edge XANES spectra; d normalized Ce-L3 edge XANES spectra; e OER (Fourier-transform of K3-weighted Ce L3-edge EXAFS spectra), f ORR (Fourier-transform of K3-weighted Ce L3-edge EXAFS spectra); g calculated ORR/OER free energy diagrams; h calculated ORR/OER overpotential of each element.
