Functional Oxide Nanosheets

￭What's nanosheet?

Nanosheets are obtained by delaminating a layered host material into its elementary sheets through soft-chemical procedures.

The nanosheet crystallites can be considered as a unique class of nanoscale materials, having an exceedingly high two-dimensionality with a molecular thickness.

Our group have reported the synthesis of several types of nanosheet materials based on titanium, manganese, and niobium oxides.

￭Nanosheet Library

Our group has successfully synthesized a variety of oxide and hydroxide nanosheets of transition metals and rare-earth metals, which exhibit attractive physicochemical properties depending on their composition and structure.

￭ New and Enhanced Physical Properties in Nanosheets

Our group has found that nanosheets exhibit new or enhanced physical properties, which are distinct from those of bulk materials.

￭ Fabrication of Nano-Structure by Nanosheets

Various new materials can be derived by using the nanosheets as building blocks.

The nanosheets are organized or assembled in various fashion through soft-chemical procedures such as flocculation and self-assembly, which leads to the fabrication of ultrathin multilayer films, restacked materials with high surface area, hollow capusles, and nanotubes.

Through these routes, we are developing useful materials such as photocatalysts, and dielectrics.
