From: CdS nanoparticles sensitization of Al-doped ZnO nanorod array thin film with hydrogen treatment as an ITO/FTO-free photoanode for solar water splitting

Figure 2

TEM analysis of the microstructure properties of AZO nanorod array thin film with hydrogen treatment. TEM images (a-c) and EDX spectrum (d) of a typical CdS nanoparticles-decorated AZO nanorod as well as the HRTEM image focused on the bare surface (e) and that focused on the CdS nanoparticles-decorated surface (f). The cycle numbers for CdS nanoparticles sensitization are 1 (a, d-f), 3 (b), and 5 (c).
