钛柱撑蒙脱石制备研究进展

摘要

钛柱撑蒙脱石作为一种大层间距的微孔材料,是一种多酸型、性能优异的催化剂和吸附剂,成为近几年来纳米多孔材料研究的热点之一.综述了钛柱撑蒙脱石制备的基本原理、主要工序、各工序工艺条件及其对柱撑蒙脱石结构与性能的影响的最新研究进展.评述了尚存在的若干科学问题和今后应重点发展方向.%As a large basal spacing, micro-pore interlay pillared material, Ti-pillared montmorillonite is a kind of multi-acid excellent catalyst and absorbent. It is one of research hotspots about porous materials in the world. In this paper,preparation theory of the pillared montmorillonite was reviewed as well as main preparation processes, conditions of each process and their effects on structure and properties of pillared montmorillonite. Several key problems and prospects were also discussed.
