Figure 3. Cryo-EM imaging of CO₂ molecules^[53]. (A) Cryo-EM image of vacuum-dried, empty ZIF-8 along the projection. (B) Magnified image of a single ZIF-8 monocyte from (A). The density near the inner edge of the single cell (blue circle) may correspond to the organic imidazolate linkers. (C) Cryo-EM image of CO₂-filled ZIF-8 particle along the projection. (D) Magnified image of a single ZIF-8 unit cell from (C). Density at the center of the unit cell (indicated by the red arrow) likely corresponds to CO₂ adsorbed within ZIF-8.
