@catherine_tays There is no optimal localization for the elements at this scale yet. The key is to maximize the synergistic effect between the N-sites on the carbon nanospheres and the metal oxides. It is also important to maintain a three-phase-boundary to keep the reactions going.

@catherine_tays Hi Catherine! In the EDX mapping, different colours indicate different elements. The mapping represents the localization of each elements and provides complementary information on the nature of the material.
