スメクタイト系多孔体の合成と触媒作用

抄録

Smectite-type porous materials having catalytically active metal cations in octahedral sheets are prepared from metal chloride and water glass with a hydrothermal method. The pore structure (surface area, pore volume and pore diameter) of the porous materials can be controlled by adjusting pH values and the addition of quaternary alkyl ammonium salts during the hydrothermal synthesis. In this manuscript, the synthesis of smectite-type porous materials is briefly described, and their catalysis and catalyst support properties for commercially important reactions are introduced. In the part of the catalysis, 1-butene isomerization, carbon dioxide insertion, and desulfurization activities of smectite-type porous materials having divalent cations (Ni^2＋, Mg^2＋, and Co^2＋) and alkali cations (Li^＋, Na^＋ and K^＋) are described. In the part of the support usage, n-butane hydrogenolysis over platinum metal particles supported on smectite-type porous materials having divalent cations (Ni^2＋, Mg^2＋, and Co^2＋), and hydrogenation of acrylonitrile-butadiene rubber in organic solvents over palladium metal particles supported on pore-size-controlled smectite-type porous materials.
