粘土粒子多孔材料の表面設計およびその評価

抄録

Synthesis and modification of porous materials such as charcoal, silicagel, zeolite are nothing but a kind of nanotechnologies. Zeolites have three-dimensional pore structure like a cage, and FSM-16 has one-dimensional pore structure like a tube. On the other hand, derivatives of clay have two-dimensional pore structure and have an ability of various applications such as adsorbent, molecular sieve, catalyst and catalytic support. They are expected to have different characteristics that are not recognized for three-dimensional and one-dimensional porous materials. Clays are made by layers composed of tetrahedral sheets and octahedral sheet, and are able to exchange ions between layers, to expand gallery height, to pillar between layers, and to modify surface hydroxyl groups, etc. Clays are thus expected to be starting materials for new porous or inorganic-organic hybrid materials.
