abstract = {Metal–support interaction effects and their consequences
in CO2/CO methanation and methane steam reforming have been
exemplarily studied on two complex Ni–perovskite powder
catalyst systems, namely Ni–La0.6Sr0.4FeO3−δ (lanthanum
strontium ferrite, LSF) and Ni–SrTi0.7Fe0.3O3−δ
(strontium titanium ferrite, STF). Pre-reduction in hydrogen
and treatment in catalytic gas mixtures cause a variety of
structural effects, including exsolution of iron particles
and formation of Ni–Fe alloy particles. These
manifestations strongly depend on the reducibility of the
perovskite and are hence much more pronounced on LSF.
Reactivity differences are strongly influenced by the
chemical properties of the respective perovskite support.
The more reducible the perovskite support, the stronger the
deviation from the catalytic behavior of a Ni/Al2O3
reference catalyst, rendering establishments of direct
structure–activity/selectivity relationships difficult.
The studies show the extreme variety of the
metal–perovskite interface, which helps in judging similar
systems of recent high catalytic importance, e.g. metals
supported on spinel or other perovskite phases.},
