Abstract
Nanocomposite system Fe/ZrO2 prepared by sol–gel synthesis was studied by the EXAFS, XRD and Mossbauer methods. According to the data of all the methods phase composition of the system depends on the percentage of Fe. Only the tetragonal ZrO2 structure is found at high Fe concentration, but at low concentration up to 1wt% of Fe, the formed ZrO2 is a mixture of monoclinic and tetragonal structures. It seems that for greater concentrations, the iron produces two-dimension layer structures. It was revealed that the iron is located on the external surface of the (1 1 1) plane of the ZrO2 nanoparticles, namely as isolated ions at concentrations less than one monolayer.
