The possible active species were proposed. The 1 mol % of iron to Si was incorporated in catalyst samples, which was prepared by sol-gel process using iron chloride and tetraethylorthsilicate (TEOS) as the sources. The incorporated trivalent iron species were characterized as tetrahedral FeOxCl4-x , and excess loaded species were aggregated to form α-Fe2O3 during drying process at 403 K. The fraction of [FeOxCl4-x], [FeCl6] and [FeO6] species in the catalyst samples were determined by the least-squares analysis of XANES.
