Zinc oxide (ZnO) nanostructures have been studied extensively in the past years due to the novel electronic, photonic, mechanical and electrochemical properties. Recently, more attention has been paid to assemble nanoscale building blocks into three dimensional (3D) complex hierarchical structures, which not only inherit the excellent properties of the single building blocks but also provide potential applications in the bottom-up fabrication of functional devices. This review article focuses on 3D ZnO hierarchical nanostructures, and summarizes major advances in the solution phase synthesis, applications in environment, and electrical/electrochemical devices. We present the principles and growth mechanisms of ZnO nanostructures via different solution methods, with an emphasis on rational control of the morphology and assembly. We then discuss the applications of 3D ZnO hierarchical nanostructures in photocatalysis, field emission, electrochemical sensor, and lithium ion batteries. Throughout the discussion, the relationship between the device performance and the microstructures of 3D ZnO hierarchical nanostructures will be highlighted. This review concludes with a personal perspective on the current challenges and future researches.

Flower-like In2S3 hierarchical nanostructures were successfully prepared via a facile solution-phase route, using thiacetamide as both sulfur source and capping agent. Our experimental results demonstrated that the morphology of these In2S3 nanostructures can be easily modified by changing the ratio of In(NO3)3/thiacetamide. With the ratio increasing from 1:1.5 to 1:6, the In2S3 crystals exhibited flower-like morphology of varying size. XRD and HRTEM of the flowers revealed the cubic structure of In2S3; morphological studies examined by SEM and TEM showed that the synthesized In2S3 nanostructure was a flower-like hierarchitecture assembled from nanoscale flakes. XPS and EDX analysis confirmed the stoichiometry of In2S3 nanoflowers. The optical properties were investigated by UV-vis DRS, which indicated that the In2S3 nanoflower samples possess a band gap from 1.90 to 1.97 eV. Furthermore, photocatalytic activity studies revealed that the prepared In2S3 nanoflowers exhibit an excellent photocatalytic performance, degrading rapidly the aqueous methylene blue dye solution under visible light irradiation. These results suggest that In2S3 nanoflowers will be a promising candidate for a photocatalyst working under the visible light range.
