Description Perovskite type catalysts with LaCoO3 and La0.9Ba0.1CoO3 compositions have been prepared by sol–gel
method and their catalytic activity was studied for CO oxidation in presence of CO2, water and also for
particulate matter (PM)/carbon oxidation. The catalysts were characterized using XRD, BET-SA, SEM,
TPD, XPS and their catalytic activity was evaluated using a steady state gas evaluation assembly, as well
as thermo gravimetric analysis. La0.8Ba0.1CoO3 catalyst shows enhanced catalytic activity as compared to
LaCoO3 for CO and PM oxidation. Barium substitution appears to be responsible for low temperature
activity of the catalyst by influencing redox and oxygen desorption properties as also suggested by
TPD studies.
