| Abstract: | By varying the initial precursor concentrations of (KOH/Zn(NO3)2 6H2O) without addition of surfactants, the branched nanostructures with different growth characteristics can be obtained. In this study, the growth behavior of the three-dimensional hierarchical structure arrays varied from randomly oriented to well-defined sixfold symmetry by altering pH value of the solution and the related effect of erosion phenomenon have been illustrated. In summary, the hierarchical structures with different morphologies can be obtained on preformed Zn microtips through a simple one-step solution method. |
