(a,b) FESEM images of ZnO. Inset of the panel c shows the interior particles at the broken part. Scale bars, 1 μm and 100 nm; a and b, respectively. (c) TEM image of ZnO. Scale bar, 500 nm. (d) HRTEM image of ZnO. Scale bar, 5 nm. (e,f) FESEM image of CuO. Inset of the panel f shows the interior particles at the broken part. Scale bars, 1 μm and 100 nm; e and f, respectively. (g) TEM image of CuO. Scale bar, 500 nm. (h) HRTEM image of CuO. Scale bar, 5 nm. SAED patterns (insets of TEM images) show the single-crystal diffraction.
