Abstract The surface analyses of Fe2O3–Sb2O4 catalysts by XPS showed that the surface of FeSbO4 grains was enriched in Sb content at the bulk compositions Sb/Fe > 1. The surface layer, which was considered to be responsible for the selective propene oxidation, had an estimated composition Sb/Fe ≅ 2, suggesting a surface compound like FeSb2O6.
