Description Ruthenium based catalysts show excellent catalytic
activity for several oxidation reactions, however,
their thermal stability has been a challenge. We have been
successful in stabilizing ruthenium in perovskite structure,
which results in a remarkable improvement in its thermal
stability. La3.5Ru4.0O13 lanthanum ruthenate type perovskite
was prepared by using various methods, including coprecipitation
as well as a template method, which resulted
in improved physical properties. This perovskite phase was
found to be thermally very stable, possibly due to the 4?
oxidation state of ruthenium in a stable matrix. In this work,
we have studied the catalytic properties of La3.5Ru4.0O13
phase for CO and hydrocarbon oxidation reactions. The
lanthanum ruthenate shows active CO oxidation beyond
about 150 and 170 �C for propene oxidation. The thermal
and chemical stability of this material makes it suitable for
various catalytic applications, while relatively insignificant
poisoning by SO2 is an important observation to further
explore.
