英文摘要: A series of Hydroxy-Fe-Al Pillared Clays (FeAl-PILC) containing mixed-metal complexes with various Fe/Al ratios were prepared by two methods. The structure of the pillaring solution was studied by Al-27-NMR, UV, ESR. The structure and thermal stability of the pillared clays were determined by XRD, DTA, UV-DRS. The results suggest that the basal spacings are 1.98-1.55nm. The pillaring structure, surface area and thermal stability of FeAl-PILC are greatly affected by Fe/Al ratios in pillaring solution, FeAl-PILC products with Fe/Al ratio<0.5 have the pillaring structure the pillaring structure similar to that of Al-PILC, but FeAl-PILC products with Fe/Al ratio >= 0.5 have the pillaring structure similar to that of Fe-PILC. The basal spacings, surface area and thermal stability decrease with increasing of Fe/Al ratio.
