Figure 2

(a) Schematic illustration for the formation of ultrathin CeO2 sheets with numerous surface pits and intact ultrathin CeO2 sheets. Note that the heating temperature and time have a vital role in the formation of pits on their surface. (b–d) Characterizations for the three-atom-thin CeO2 sheets with numerous surface pits: (b) HRTEM image, (c) AFM image and (d) the height profile along the white line indicated in (c). The scale bars in (c) and (d) are 3 and 100 nm, respectively. The inset circles and arrows in (b) and (c) denote the presence of pits on their surface.
