Title: Catalytic properties of mesoporous molecular sieves for the reduction of NOx
Abstract: The catalytic properties of Pt, Rh and Co supported on mesoporous molecular sieves with MCM-41 type structure for the reduction NO with propene were investigated. Strongly acidic sites were incorporated by co- impregnation of the catalysts with H3PW12O40. Pt/MCM-41 was found to be the most active catalyst, however, the selectivity to N2 formation was rather low. RhIMCM-41 was less active, but had a significantly higher selectivity to N2 formation compared to Pt/MCM-41. Co/MCM-41 had the lowest activity among the series of catalysts studied. In the presence of water vapor a significant increase in the activity was observed for the Pt and H3PW12O40 containing catalysts, while for all other catalysts studied the typical decrease in the activity was found.
