聚合物中分子筛的合成

Synthesis of Molecular Sieves in Polymer Hydrogels

聚合物可作为空间限制剂或介孔导向剂在一定程度上控制分子筛的尺寸和形貌,进而影响分子筛的反应活性、寿命和产物选择性。综述了近年来国内外聚合物中合成分子筛的新进展。系统介绍了聚合物中空心/核壳结构分子筛、介孔分子筛以及复合分子筛的合成;简要介绍了聚合物的添加对分子筛尺寸和形貌的影响。

Polymer can function as a space-confinement additive or a mesopore-forming agent in the synthesis of zeolites with controllable sizes and shapes, and significantly affect the activity, lifetime and selectivity of zeolites. Synthesis of molecular sieves in polymer hydrogels is reviewed. The synthesis of hollow/core-shell zeolites, mesoporous zeolites and composite molecular sieves are investigated. Moreover, the effects of polymers on size and shape of zeolites are introduced briefly.
