Abstract
In this work, thermal shock and simultaneous removal reaction for NOx, soot over Pt catalysts using $TiO_2$, $Al_2O_3$ as support were studied. The catalytic reaction test for NOx and soot were also performed independently and simultaneously, as a result, it showed different NOx removal efficiency and soot oxidation rate according to support and phase, and the onset temperature of soot oxidation has correlation to NOx removal efficiency for the catalyst. The onset temperature of soot oxidation shifted to lower temperature by generated $NO_2$ at the simultaneous reaction for NOx and soot. Also Pt/$TiO_2$ catalyst is more affected than Pt/$Al_2O_3$ on NOx removal efficiency caused by thermal shock while Pt sintering effect induced to reduce the performance on soot oxidation rate for all catalysts.
