摘要：
Several potential support materials were mixed with soot and subsequently the combustion temperature of the soot in 15% O2 was determined. Al2O3 and SiO2 showed no catalytic effect, TiO2 and ZrO2 lowered the soot combustion temperature with 80-90 K, whereas CeO2, La2O2CO3 and V2O5 (reference catalyst) showed a substantial activity for soot combustion. After poisoning with sulfur dioxide, the catalytic effect of CeO2 was strongly inhibited, whereas La2O2CO3 and V2O5 retained their high activity.
