Synthesis of novel substituted micas and interlayer pillared nanoporous solids

合成了一种新型取代可膨胀云母。制备层间柱状微孔固体，即柱状云母，也进行了使用取代的云母作为宿主晶体。成功地合成了一系列取代锗和取代硼的可膨胀云母，并将其用作插层的宿主晶体。通过插层得到的柱状云母的孔隙性质随着宿主取代云母的组成而改变。含有NaCl作为助熔剂的原料产生可膨胀的云母晶体，具有六方的片状形态，具有较大的纵横比。

Synthesis of novel substituted swellable micas was undertaken. Preparation of interlayer pillared microporous solids, i. e. pillared micas, was also undertaken using the substituted micas as host crystals. Series of Ge-substituted and B-substituted swellable micas were successfully synthesized and allowed to use as host crystals for intercalation. The pore properties of the pillared micas thus obtained by the intercalation changed, depending on the composition of host substituted micas. Raw materials containing NaCl as a flux yielded swellable mica crystals having a hexagonal, plate-like morphology with a larger aspect ratio.
