Figure 2: Composition and structure of the Titanium-modified hematite mesocrystals a. HAADF-STEM image of the mesocrystal after being exposed to 700 °C. The dark spots on top of the particle are pores. b. EELS spectra of the selected regions in image a. show that for Region 1 (the outside surface of the mesocrystal)- titanium and oxygen are present, but there is hardly any iron. There is comparatively less titanium in Region 2 (the smooth surface of the mesocrystals) than in Region 3 (edges of the mesocrystal pores). c. Chemical composition map of iron, oxygen and titanium
