From: Synthesis of multi-shelled ZnO hollow microspheres and their improved photocatalytic activity
TEM, HRTEM, and STEM images and EDS spectrum of ZnO hollow spheres. (a-d) TEM images of the triple-, double-, and single-shelled ZnO hollow spheres and ZnO nanoparticles. (e-g) High-magnification TEM images of the triple- and single-shelled ZnO hollow spheres. (h, i) STEM images of the triple-, double-, and single-shelled ZnO hollow spheres. (j, k) HRTEM image and EDS spectrum of an individual triple-shelled ZnO hollow microsphere. The inset of Figure 5k is the SEM image of the sample, and the place marked by a rectangle shows the specific position of EDS analysis.
