Syntheses of Zinc Oxide and Zinc Hydroxide Single Nanosheets

In this study, we present the preparation of zinc oxide (ZnO) and zinc hydroxide (Zn(OH)(2)) single nanosheets for the first time. ZnO nanosheet was prepared by delamination of layered ZnO intercalated with the dodecyl sulfate (DS) ion which was synthesized by cathodic electrodeposition process. In this case, the addition of La(3+) ion into the electrolyte was very critical for the further delamination process. On the other hand, Zn(OH)(2) nanosheet was prepared by delamination of layered Zn(OH)(2) intercalated with the DS ion that was prepared by a soft solution process using hexamethylenetetramine (HMT). The thicknesses of the ZnO and Zn(OH)(2) nanosheets were about 0.7 and 1.0 nm, respectively. The structures of the nanosheets were discussed with the results of transmission electron microscopy (TEM) and selected area electron diffraction (SAED) images.
