We focus on the control of crystal structures by soft-chemical and hydrothermal methods as well as conventional solid-solid synthesis. These different synthesis routes produce new inorganic compounds, and their applications, especially as mesoporous materials for specific absorption properties, are examined.

Research subjects

1. Soft-Chemical Properties on Layered Compounds

New inorganic compounds are synthesized by topotactic reaction, such as ion-exchange reaction and intercalation, especially for layered phosphates, clay minerals and nitrides.

2. Synthesis of New Inorganic Compounds under Hydrothermal Condition

Novel inorganic compounds are synthesized by low-temperature hydrothermal method, which enables us to sustain initial structures and valence.

3. Porous Composite of Inorganic-Organic Compounds

Inorganic porous materials with controlled-shaped pores are synthesized by micelle molecular. We attempt to improve absorption properties by such chemical modifications.
