From: Single Crystalline Co3O4 Nanocrystals Exposed with Different Crystal Planes for Li-O2 Batteries
Structure analysis of Co3O4 crystals.
HRTEM, fast-Fourier-transform (FFT), lattice and atom resolved HRTEM images of Co3O4 nanocrystals exposed with different crystal planes: nanocubes (a1–a4), pseudo octahedrons (b1, b2), nanoplatelets (c1, c2), hexagonal nanosheets (d1–d4) and nanolaminar (e1–e4). Insets in a1, b1, c1, d1 and e1 are corresponding geometric models. Left-top corner inset in b2 and inset in c2 are the corresponding FFT patterns. Insets in a4, d4 and e4 are the crystal structure of {100}, {111} and {112} crystal planes. Left-bottom inset in b2 is the lattice resolved HRTEM image and corresponding crystal structure of {110} crystal planes.
