SEM micrograph of NsARC morphology showing high specific surface area. (a) Fracture surface showing crystals extending the entire depth of the coating and showing porosity between crystals. (b) Scraped off anatase mille-feuilles crystals showing the nanoplate structure. (c) Plan view SEM image showing the porosity between columns and between mille-feuilles plates.
