Catalytic removal of soot particulate in the presence of excess oxygen was investigated over perovskite-type oxides by using temperature programmed reaction(TPR) in which carbon particulate/catalyst mixture was heated in the reaction gas containing nitric oxide and oxygen. LaCoO₃ catalyst was modified to enhance the activity by substitution of metal ion into A and B sites. The reaction conditions was also examined.
