  text: This work presents a new and facile route for the preparation of iron oxide-based
    catalysts supported on alumina, which enables the targeted synthesis of catalysts
    with an increased amount of isolated tetrahedrally coordinated iron centers compared
    to a conventional impregnation procedure, and therefore leads to an increase in
    activity for CO oxidation reaction. By a multi-step impregnation–calcination protocol,
    the catalysts were synthesized with iron loadings of between 1 and 10 wt%, and
    their catalytic activity was then compared with a 10 wt% loaded catalyst prepared
    by conventional single impregnation. With a loading of 8 wt%, the presented catalysts
    showed an improved catalytic activity regarding light-off and full conversion
    temperatures compared to this reference. Through the application of several analytical
    methods (PXRD, PDF, DRUVS, SEM, XAFS), the improved catalytic activity can be
    correlated with an increased amount of isolated iron centers and a significantly
    reduced fraction of agglomerates or particles.

  text: <The replacement of noble metal catalysts by abundant iron as an active compound
    in CO oxidation is of ecologic and economic interest. However, improvement of
    their catalytic performance to the same level as state-of-the-art noble metal
    catalysts requires an in depth understanding of their working principle on an
    atomic level. As a contribution to this aim, a series of iron oxide catalysts
    with varying Fe loadings from 1 to 20 wt% immobilized on a γ-Al2O3 support is
    presented here, and a multidimensional structure–activity correlation is established.
    The CO oxidation activity is correlated to structural details obtained by various
    spectroscopic, diffraction, and microscopic methods, such as PXRD, PDF analysis,
    DRUVS, Mössbauer spectroscopy, STEM-EDX, and XAS. Low Fe loadings lead to less
    agglomerated but high percentual amounts of isolated, tetrahedrally coordinated
    iron oxide species, while the absolute amount of isolated species reaches its
    maximum at high Fe loadings. Consequently, the highest CO oxidation activity in
    terms of turnover frequencies can be correlated to small, finely dispersed iron
    oxide species with a large amount of tetrahedrally oxygen coordinated iron sites,
    while the overall amount of isolated iron oxide species correlates with a lower
    light-off temperature.
