Synthesis of hexaqonal ZnO microtubes by a simple soft aqueous solution method

Abstract

A facile novel approach to synthesize the hexagonal zinc oxide microtubes is demonstrated at low temperature and normal pressure under a kind of soft aqueous solution method. Hexagonal-faceted ZnO tubes with length of 1 fim, diameter of 300 nm and shells thickness of 30 nm on average were synthesized by this new simple method. The SEM results indicate that the drying temperature played an important role on the formation of hexagonal ZnO microtubes. It was interesting to find that ZnO particles exhibited different morphologies on changing the reaction temperature. The growth mechanism is briefly discussed in this paper.
