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 film 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.
