ABSTRACT
This chapter discusses advances in dimensionality transformation of layered materials. The dimensionality of nanostructured materials is an important parameter because it is strongly correlated with the properties of materials. Nanostructured materials, such as nanoparticles, nanorods, nanosheets, and nanoporous materials, are of great importance for the development of nanotechnology. Nanoparticles have unique nano-size effects, and nanoporous materials can be used for materials storage, materials transport, and reaction fields. Dimensionality transformation is a useful way to control nano-structures with different dimensionalities. Topotactic conversion of a nanostructured material with specific dimensionality leads to the modification of the nanostructural dimensionality. Two-dimensional (2D) layered materials have different sizes along normal and lateral directions of the basal plane and are expected to be useful as host materials with a two-dimensional nanospace. Most layered materials can be inserted with ions or molecules between layers (intercalation). Nanoporous materials are representative 3D nanostructured materials.
