层柱粘土是一种具有二维层柱结构的新型催化剂材料,它的层间距比沸石分子筛孔口大,适于较大分子的反应。本文着重论述了层柱粘土的制备、催化作用、热稳定性及酸性。
Pillared clay is a new type of catalyst material with two-dimensional pillared structure. Its interlayer spacing is larger than that of zeolitic molecular sieve and is suitable for the reaction of larger molecules. This article focuses on the preparation, catalysis, thermal stability and acidity of pillared clay.
