英文摘要: Hydroxy-Fe-Al Pillared Clays (FeAl-PILC) containing mixed-metal complexes with various Fe/Al ratios were characterized by UV-DRS. Mossbauer spectrascopy, XPS, TPR measurement. The surface hydroxyl and acidity were determined by IR, Py-IR and TPD. The results have shown that iron in the pillars relatively stronger interacts with alumina in the pillars than with silica of interlayer. The interaction is stronger in FeAl-PILC with Fe/Al ratio<0.5 than that with Fe/Al ratio>0.5. The surface acidity is decreased with increasing of Fe/Al ratio.
