abstract = "Identification of highly active iron sites in N2O-activated Fe/MFI was analyzed. Reduction in an H2 flow at 600°C of Fe/MFI prepared by chemical vapor deposition and followed by its exposure to N2O at 250°C produced 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 density functional theory (DFT) calculations suggested that in this state some Fe will be present in the oxidation state of Fe4+.",
