Abstract ZnO nanotowers have potential advantages in field emissions, photocatalysis, self-cleaning devices, solar cells and chronic-disease diagnosis. In this paper tailored size and apex angles of the pencil-like ZnO nanotower arrays were obtained by the aqueous solution method via systematically controlling the ammonia volume. The relationship between the main Zn-containing species in the precursor solutions and the ammonia volume was analyzed by the X-ray powder diffraction and infrared spectra. The effects of different proportion of Zn-species on the characteristics of ZnO nanotower arrays were explained by chemical reaction kinetics.
