Co1 - xLaxOy catalysts were synthesized by citric acid complex method and their catalytic activities for soot combustion in air were investigated in this study. The best performance was observed over Co0.93La0.07 oxide catalysts with T-50 = 402 degrees C. Co4+ in the surface of LaCoO3 leads to the formation of more oxygen vacancies, thus contributing to the activities. (C) 2014 Elsevier B.V. All rights reserved.
