| Abstract: | ZnO hollow micro/nanostructures were fabricated by a novel fast hydrothermal method based on the microemulsion. The aqueous
reverse micelles were used as templates and different amount of Zn2+ colloid was compelled to hydrolyze on its surface. Scanning electron microscopy indicates that the products grown in the
solution with colloid volume concentration of 12.3 and 0.5 v.% are hollow nanospheres and hexagonal microtubes, respectively.
It is believed that this difference should attribute to the initial shape of hydrolysate and the core/shell state of water/surfactant
during hydrothermal treatment. |
