Approaches to the Synthesis of Supergallery Pillared Clays,ercalates in which the interlayer thickness is substantially larger than the thickness of the host layer. Three general classes of hosts are considered, namely, 2:1 smectite clays,layered double hydroxides (LDHs), and layered silicic acids. The direct intercalation of metal oxide sol particles can b

Preparation and Properties of Pillared Synthetic Boron-Containing Saponite,O. The alumina-pillared synthetic boron-containing saponite possessed both higher cumene dealkylation activity and better benzene selectivity than alumina-pillared non-boro

Surface and Cracking Properties of Expanded Clays Dried with a Supercritical Fluid,als with high (450-650 m./g) surface area, macroporosity (350-400 m./g) , and pore volume (~1.5 cc/g) , which are thermally stable to 800°C. If drying at supercritical conditions is replaced by air drying (AD), the clays lose their macroporosity, and in the case of montmorillonite, a large decrease

TEM Characterization of Pillared Rectorites,with Al203-clusters. The regular 1:1 interstratification of mica-like and montmorillonite-like layers yield (variable) interlayer spacings of about 28Å. Nonuniform pillar distributions have been attributed to layer charge heterogeneity and to pillar deformation. Other defects, like stacking faults,

Layered Silicates: The Protonation Behavior of KHSi2O5.,potassium hydrogen disilicate, KHSi.O5. Crystals of KHSi.O. were prepared hydrothermally and obtained in high yield. Protonation of this material with excess acid rapidly produces crystalline H.Si.O.. Although the bulk crystal morphology is retained during protonation, significant reorganization of
