HC-SCR of lean NOx over hydrothermally stable mesoporous aluminosilicate |
| 초록 |
Platinum catalysts supported on the hydrothermally stable mesoporous aluminosilicate (SM-41) were studied for the selective catalytic reduction (SCR) under lean burn condition. SM-41 has been synthesized by adopting zeolite seeds crystallization method and exhibited higher resistance to hydrothermal treatment and higher hydrophobicity than MCM-41. Pt/SM-41 catalyst showed higher NO conversion and N2 yield than Pt/MCM-41 for the selective catalytic reduction of NO with C3H6 in the presence of 5 vol.% O2 and 10 vol.% water vapor. In addition to high activity, hydrothermal stability and hydrophobicity of Pt/SM-41 seems to be beneficial for the selective catalytic reduction of NO in the presence of water vapor. |
