“…Montmorillonite is pillared by zirconium oligomeric polynuclear hydroxyl cation with tetramer form and then calcinates to Zirconium pillared bentonite (Zr-PILM) which is a porous pillared interlayered clay material. Because of the larger specific surface area, lamellar spacing and appropriate acid sites, Zr -PILMs are often used in the removal of nitrogen oxides [4] , H 2 S oxidation [5] , benzene alkylation [6] , Methanol-to-Olefins(MTO) [7] and some other catalytic reactions. Burch R [7] , Kikuchi E [8] , Sun Kou M R [9] et al abroad prepared Zr-PILM by immersion method and discussed the catalytic activities in the MTO reaction.…”

Zr-pillared Montmorillonites (Zr-PILM) were prepared by the hydrothermal method with montmorillonite as raw material and zirconium oxychloride as Zr source of pillaring agent. The properties of the samples were characterized by XRD,BET, SEM, TEM, XPS. Effects of the synthesizing conditions on the structures of Zr-PILM were investigated. The results indicate that Zr-PILM retains complete layered and sheeting structure, and its BET surface area and micropore volume increases greatly. ZrO2 exists in Zr - PILM layers.The catalytic reaction result of MTO shows that Zr-PILM has high catalytic activities for MTO reaction.
