Selective Reduction of Nitrogen Monoxide with Hydrocarbons over SnO2 Catalyst

Abstract

Abstract SnO2 showed catalytic activity for the selective reduction of NO with hydrocarbons (C2H4, C3H8, and CH4) in the presence of excess oxygen, and the activity was not so much decreased even after heat treatments in dry air at 900 °C as well as in humid air at 800 °C. These results show that SnO2 is an active and stable catalyst for the reaction.
