Fig. 4

STXM images of the ZnO nanorods and their corresponding XAS spectra. The STXM images were obtained at 1021.3 eV (Zn L-edge) and 537.2 eV (O K-edge). XAS spectra: a Zn L 3 -edge and c O K-edge for ZnO-4/FTO and b Zn L 3-edge and d O K-edge for ZnO-4/Si(001). We obtained these spectra of the nanorods after separating them from their respective substrates by using an ultrasonicator
