-shaped ZnO structure is very sensitive to the growth conditions and it appears to be difficult to get reproducible results.
It was also reported that ZnO nanotube arrays were grown on zinc foils via a hydrothermalprocess, attributed to the gradient in the concentrations of zinc precursors from Zn foil

demonstrating a single crystalline structure.
The width, length and density of the nanorods on the substrates are dependent on the synthesis conditions, such as, seeding of the substrates, concentration of precursors in the growth solution, as well as the duration of hydrothermalprocess [27][28][29]. The
