Abstract
Platinum catalyst supported on a medium surface area β-SiC was successfully used for the catalytic combustion of model carbon particles and compared to a catalyst supported on a low surface area α-SiC. The β-SiC-based catalyst showed no deactivation as a function of cycling tests while a strong deactivation was observed on the α-SiC-based catalyst. This deactivation was attributed to the progressive encapsulation of the platinum particles by a layer of silica which built up during the combustion cycle. These results render possible the use of Pt/β-SiC catalyst as a diesel carbon particle catalytic filter with continuous regeneration.
