V 2 O 5 -SnO 2 double-shelled nanocapsules and their formation process. (a) Schematic presentation of the formation process of V2O5-SnO2 double-shelled nanocapsules based on Ostwald ripening. (b) SEM image of V2O5-SnO2 double-shelled nanocapsules. Inset shows the schematic structure of these double-shelled nanocapsules. (c-e) TEM images indicate that the porous shell consists of a great deal of nanocrystals. (f-h) HRTEM images revealing lattice planes of the V2O5 matrix and SnO2 nanocrystals. (i) SAED pattern taken from individual nanocapsules which shows that these nanocapsules are polycrystalline. Adapted from [62] and reproduced with the permission of the American Chemical Society.
