本文介绍了新一代的磷酸铝及杂原子磷酸铝分子筛。这些分子筛均是采用水热晶化法合成的,其中加入的有机模板剂起结构导向作用。它们的结构有三维网络的,也有二维层状的。其中很多分子筛都有优良的热稳定性或水热稳定性。有部份分子筛呈现出酸催化性质。
This article describes a new generation of aluminum phosphate and heteroatomic aluminum phosphate molecular sieves. These molecular sieves are synthesized by hydrothermal crystallization method, in which the organic template added by the structure-oriented role. Their structure has three-dimensional network, but also two-dimensional layered. Many of these zeolites have excellent thermal or hydrothermal stability. Some zeolites showed acid-catalyzed properties.
