a Co and Fe L-edge EELS and the corresponding STEM-EELS element maps of CoFe-NBs. (Note: EELS data were recorded through integration of the central part of the box particle, and the F signal arises from Nafion.) b, c Co K-edge XANES and FT-EXAFS spectra of CoFe-NBs. d WT contour profiles of Co K-edge EXAFS spectra of CoFe-NBs.
