Abstract

<abstract abstract-type="main" id="pssr201510072-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>The self‐regenerative property of LaCo_{1–<italic>x</italic> –<italic>y</italic>}Pd<italic>_x</italic> Zn<italic>_y</italic> O_3±δ and LaFe_{1–<italic>x</italic> –<italic>y</italic>}Pd<italic>_x</italic> Zn<italic>_y</italic> O_3±δ solid solutions with monometallic Pd or bimetallic Pd/Zn substituents for Co or Fe is studied under a redox cycle by high angular annular dark‐field scanning transmission electron microscopy (STEM‐HAADF) and energy dispersive X‐ray spectroscopy (EDX) and X‐ray diffraction (XRD). These results reveal that the composition of perovskites determines the self‐regenerative property that occurs largely in LaCo_{1–<italic>x</italic> –<italic>y</italic>}Pd<italic>_x</italic> Zn<italic>_y</italic> O_3±δ but is limited greatly in LaFe_{1–<italic>x</italic> –<italic>y</italic>}Pd<italic>_x</italic> Zn<italic>_y</italic> O_3±δ.
