Due to its unique surface effects, volume effects and quantum effects, nanomaterials have broad applications in the fields of chemical engineering, bioengineering, medicine, and energy. A number of studies have been carried out using simple low-dimensional nanostructures as the main building blocks to assemble into a regular ordered three-dimensional structure, i.e., hierarchical nanostructures, in a specific arrangement. In this paper, the research progress of hierarchical nanostructures is reviewed. The microstructure of graded nanomaterials and the preparation of graded nanostructures are introduced respectively. The applications of graded nanomaterials in wastewater treatment, supercapacitors, solar cells and photocatalysis are also prospected.

Key words: nanomaterials, controllable preparation, graded nanostructures, photocatalysis, supercapacitors
