Abstract：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.
