A Ce-Sn-Ox catalyst for the selective catalytic reduction of NOx with NH3

A Ce-Sn-Ox catalyst prepared by the conventional coprecipitation method has been developed for the selective catalytic reduction of NO with NH3. The Ce-Sn-Ox catalyst showed good activity and high resistance to the poisonous effect of K2O and PbO in a temperature range from 100 °C to 400 °C and displayed well SO2/H2O durability at 300 °C.
