Description BaRuO3 based perovskite type catalytic material was synthesized by co-precipitation method and its
catalytic activity has been tested for diesel soot oxidation. This material shows high catalytic activity for
carbon/soot oxidation reaction with lowering of carbon oxidation temperature by >190 8C. The catalytic
activity could be due to dissociative adsorption of oxygen on BaRuO3 surface. It is postulated by
structural investigations that 120 planes of BaRuO3 can have abundant Ru atoms which can facilitate the
oxygen dissociation. The additional advantage of using Ru in BaRuO3 is the thermal stability of Ru in
oxide matrix as well as basicity offered by Ba. These synergetic effects can also be responsible for the high
soot/carbon oxidation activity of this perovskite type material, which can be a potential candidate for
control of soot emissions from combustion processes and vehicle exhaust.
