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 La3誉 into the electrolyte was very critical for the further delamination process. On the other hand, Zn(OH)2nanosheet was prepared by delamination of layered Zn(OH)2intercalated with the DS−ion that was prepared by a soft solution process using hexamethylenetetramine (HMT). The thicknesses of the ZnO and Zn(OH)2nanosheets 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. [ABSTRACT FROM AUTHOR]
