Figure 13.11
Upper left: SEM images of the calcined sample showing the
morphology of sphere. (a) Overview morphology of the bulky spherical silica.
Scale bar: 2
μm. (b) High magnifi cation SEM image of one sphere exhibiting the
radiolarian-like morphology. Scale bar: 290 nm. The inset image shows the silica
skeleton of a radiolarian. Lower left: TEM images of the calcined silica sphere.
(a) The circle-shaped projection of one sphere. Scale bar: 100 nm. (b) HRTEM
reveals that the bundle-like pattern is composed of radial streaks with the
oriented periodic distance of 4 nm. Scale bar: 60 nm. (c) The selective district
HRTEM on the center of circle-shaped projection of sphere. Scale bar: 60 nm.

“chemical snapshots,” revealing the diversity in slices and vesicles (a) and also
their intermediate morphologies shown in (b-e), respectively. The applied reaction
ratios are shown between the brackets. (Reprinted with permission from [65])
