Abstract

A new bidimensional zeolite containing 8R and 12R pores, denoted as ITQ-32, has been synthesized and its structure solved from powder X-ray diffraction data. This zeolite presents a relatively large pore volume (0.16 cm3/g) and pore apertures of 3.5 x 4.3 A and can be prepared as a nearly pure silica zeolite and as aluminosilicate. In the latest case, acidic properties are developed.

摘要

一种含有8R和12R孔道的新型二维沸石，记为ITQ-32，已被合成，并根据粉末X射线衍射数据解析了其结构。这种沸石具有相对较大的孔体积（0.16 cm³/g）和3.5×4.3 Å的孔口，可以制备成几乎纯的硅沸石和铝硅酸盐。在最新的情况下，会展现出酸性性质。
