Ferrisilicate analogs of ferrierite (FER) type zeolite having SiO2/Fe2O3 ratios ranging between 30 and 200 have been synthesized using pyrrolidine as the templating agent. On calcination, the samples develop a typical buff color indicating conversion of some tetrahedral Fe3+ into octahedral Fe3+. Correspondingly, a doublet in the Mossbauer spectrum with isomer shift at 0.15 and 0.68 mm s(-1) was observed. The Fe-FER samples were further characterized by UV-v?s, IR and TG/DTA. Fe-FER samples were found to exhibit catalytic activity for n-hexane oxidation reactions with !hydrogen peroxide as oxidizing agent.
