摘要：
The structure of binary iron-cobalt oxide nanosystems—precursors of bimetallic catalysts—is studied by Mössbauer spectroscopy, X-ray diffraction, and small-angle X-ray scattering. The oxide system under study represents a promising material for creating new metallic nanocatalysts for ammonia synthesis. The structural evolution in the composition range 100Fe/0Co-5Fe/95Co is found to correspond to the transition from fine-grained α-Fe2O3 to mixed iron-cobalt spinels of various compositions and degrees of dispersity.
