Figure 3

(a) Low magnification TEM image of CuO. (b–c) High magnification TEM images of CuO. (d–e) Lattice resolved HRTEM images of CuO. (f) Crystal structure of {001} crystal planes of CuO. Insets in (a), (b) and (c) are selected area electron diffraction (SAED) patterns. Insets in (d) and (e) are fast-Fourier-transform (FFT) patterns.
