Abstract
Zinc Oxide (ZnO) submicron lamellar and rod clusters with well-controlled morphologies have been synthesized by conventional and microwave accelerated reaction methods. Zinc nitrate hexahydrate and sodium hydroxide were used as a precursor. The pH of the precursor solution (zinc nitrate hexahydrate) was increased by ∼12 via the controlled addition of sodium hydroxide (NaOH). Based on electron microscopy images and X-ray Diffraction (XRD) patterns, the microwave accelerated reaction method shows improved shape of controllable lamellar and flower like rod clusters.
► Hexagonal phase of ZnO-nanorod arrays are composed from two different methodologies. ► An improved shape of controllable lamellar and rod clusters is procedure from microwave method. ► Initial precursors are Zn(NO3)2 and NaOH, which control the pH to stabilize the morphologies.
