Chemical Synthesis Of Zinc Oxide Nanorods And Their Transformation Intonanotubes, Pijus Kanti Samanta

Turkish Journal of Physics

A simple wet chemical method was successfully deployed to synthesize zinc oxide nanorods and nanotubes of hexagonal morphology. Energy dispersive X-ray spectroscopy confirmed the formation of ZnO with almost equal atomic percentages of Zn and O atoms. The FESEM images confirmed the formation of ZnO nanorods and nanotubes of length 1.5 to 2 $\mu $m and diameter 500 nm to 1 $\mu $m. The growth of the nanorods saturated under the combined effect of ionic association of Zn$^{2+}$ and OH$^{-}$ ions, Gibbs' energy of the reaction, reaction temperature, and the enthalpy of the system. Further stirring led to dissolution resulting …
