Interfacial oxygen vacancies (VO) in MCs. a, b HAADF-STEM images of Fe2O3 MC and c corresponding EELS chemical composition maps of panel b. d EEL spectra of panel b and e corresponding EELS Fe-L2,3 spectra of the selected region in panel b. The rightmost one of panel c is merged image of components 1 (red), 2 (green), and 3 (blue). f EPR spectra of the samples. g Schematic illustration of the VO formation in MC, where (100) facets are tentatively assumed to form the interface
