Zn based hydroxide double salts (Zn-HDS) with an interlayer spacing of 20 A was produced by dissolving dumbbell-like ZnO crystal. The resulting Zn-HDS with a ribbon-like shape has a suitable morphology to explore the remarkably mild procedure for synthesis of ZnO nanobelts. We found that the intercalated water molecules into the Zn-HDS could play a key role in the ZnO nanobelts porosity. The nonporous ZnO nanobelts were successfully synthesized from the Zn-HDS by soft-solution process at 95 {sup o}C through mild dehydration agent as Na{sub 2}CO{sub 3}. As-synthesized ZnO nanobelts were grown along not only the [0 1 -1 0], but also the [2 -1 -1 0]. On the other hand, the porous ZnO nanobelts were obtained from the Zn-HDS by calcinations at 200 and 400 {sup o}C. In addition, flower-like ZnO multipod and hierarchical nanostructures were produced from the Zn-HDS by using of strong dehydration agent (NaOH) through hydrothermal reaction at 150 and 230 {sup o}C. - Graphical abstract: Porous and nonporous ZnO nanobelts, multipod, and hierarchical nanostructure were successfully synthesized from Zn based hydroxyl double salts by hydrothermal reaction.
