The ZrO2 and Fe2O3ZrO2 pillared interlayered montmorillonite(ZrPILM and FZPILM)were prepared by crosslinking montmorillonite with solution of zirconyl oxyhalides or solution of zirconyl oxyhalides doped with FeCl3 respectively.The value of PILMs basal spacing increases from 160nm to 180nm when corsslinking agent is aged at 85℃ for 4 hours.A4ZrPILM possesses thermal stability up to 650℃.The results of XRD,BET and DTA show that the surface area and thermal stability of 02FZPILM are higher than that of ZrPILM.Calcinated at 650℃,the retention surface area of 02FZPILM is 956% and that of ZrPILM is only 693%.02FZPILM possesses pillaring stucture at 750℃.When the molar ratio of Fe/Zr in the crosslinking agent is equal to 05,05FZPILM forms a new XRDs peak whose basal spacing is about 138nm.
