Abstract
Shape selectivity has been an important and valid concept in heterogeneous catalysis since the discovery of methanol to gasoline (MTG) conversion by Mobil Oil Co. The most popular shapeselective catalyst is zeolite, of which the pore size is comparable with the dimension of many simple molecules. The reactions of such molecules are often controlled in selectivity by the use of zeolite as a catalyst. Clay intercalation compounds have also been given attention as the shapeselective catalyst. The interlayers of several kinds of clay can be cross-linked by the “pillar” which controlls the interlayer spacing. This review describes the synthetic method of clay intercalation compounds and their application to shape-selective catalysts.
