Abstract

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.
