The most effective approach to practical exploitation of the layered solids that often have unique valuable properties—such as graphene, clays, and other compounds—is by dispersion into colloidal suspensions of monolayers, called liquid exfoliation. This fundamentally expected behavior can be used to deposit monolayers on supports or to reassemble into hierarchical materials to produce, by design, catalysts, nanodevices, films, drug delivery systems, and other products. Zeolites have been known as extraordinary catalysts and sorbents with three-dimensional structures but emerged as an unexpected new class of layered solids contributing previously unknown valuable features: catalytically active layers with pores inside or across. The self-evident question of layered zeolite exfoliation has remained unresolved for three decades. Here, we report the first direct exfoliation of zeolites into suspension of monolayers as proof of the concept, which enables diverse applications including membranes and hierarchical catalysts with improved access.

实际开发通常具有独特有价值的特性（例如石墨烯，粘土和其他化合物）的层状固体的最有效方法是将其分散到单层胶体悬浮液中，称为液体剥落。这种基本预期的行为可用于将单分子层沉积在载体上或重组为分层材料，以通过设计生产催化剂，纳米器件，薄膜，药物递送系统和其他产品。沸石被认为是具有三维结构的非凡催化剂和吸附剂，但是却以出乎意料的新型层状固体形式出现，这些层状固体具有以前未知的有价值的特征：内部或横向具有孔的催化活性层。层状沸石剥落的不言而喻的问题在过去的三十年中一直没有得到解决。这里，
