Reduction in an H{sub 2} flow at 600 C of Fe/MFI prepared by chemical vapor deposition, followed by its exposure to N{sub 2}O at 250 C, produces a highly active state characterized by an unusual TPR spike at 200 C. In situ X-ray absorption near-edge structure, X-ray absorption fine structure data and literature data on DFT calculations suggest that in this state some Fe will be present in the oxidation state of Fe{sup 4+}.
