双金属柱撑蒙脱石制备及应用研究进展

 双金属柱撑蒙脱石在吸附、催化领域具有广阔的应用前景。综述了近年来双金属柱撑蒙脱石制备过程中柱化剂制备、柱撑方法及其在催化和吸附领域的应用，指出制备周期较长、热稳定性和水热稳定性不高、孔径分布不均等是目前双金属柱撑蒙脱石研究中存在的主要问题。今后研究中，采用多金属柱撑，引入稀土金属，探究柱撑机制，分析结构与性能的关系，制备高性能、多功能蒙脱石材料将成为主要方向。

Preparation and Application of Bi-metal Pillared Montmorillonite

The bi- metal pillared montmorillonite is an important type of the pillared montmorillonite. It has application prospects in both adsorption and catalysis. This paper reviews the preparation of the pillaring agent, the approach of the pillared montmorillonite as well as the application in catalysis and adsorption. The long preparation period, the unsatisfactory thermal and hydrothermal stability and the uneven distribution of pores are the major problems. In future studies, the multimetal pillared structure or the introduction of rare earth metals, the mechanism, the retationship between structure and properties and the preparation of high-performance, multifunctional montmorillonite materials are the main subjects.
