Dependence of the photocatalytic activities of zinc oxide (ZnO) nanostructures on their morphology was investigated experimentally. Spherical and nanorod morphologies of ZnO nanostructures were synthesized by laser ablation and hydrothermal methods respectively, and were characterized by FESEM images and UV-Vis-NIR spectra. The bandgap energy of ZnO nanospheres was 3.75 eV, while for the ZnO nanorods […]
