Characterizations of nanostructures from electron microscopy technique. (A) SEM image of ZIF-8. (B,C) TEM images of ZIF-8 at different magnifications. (D) SEM image of Mo@ZIF-8. (E,F) TEM images of Mo@ZIF-8 at different magnifications. (G) EDX analysis of Mo@ZIF-8. The images indicated that Mo had been doped to the nanostructures.
