Assisted-hydrothermal Synthesis and Characterization of Flower-like ZnO Nanostructures

摘要

Flower-like nanostructures formed by ZnO nanorods were synthesized anddeposited on seeded silicon and glass substrates by a hexamethylenetetramine(HMTA) - assisted hydrothermal method at low temperature (90 oC) withmethenamine ((CH3)6N4), as surfactant and catalyst. The substrates were seededwith ZnO nanoparticles. The structure and morphology of the nanostructures werestudied by means of x-ray diffraction (XRD), high resolution transmissionelectron microscopy (HRTEM), and scanning electron microscopy (SEM) techniques.Influence of the seed nanoparticle on the formation of the flower-like ZnOnanostructures is demonstrated. The influence of the organic oxygenated chainson the crystalline habit during the growth process is also observed.
