New Insight into the In Situ SO<sub>2</sub> Poisoning Mechanism over Cu-SSZ-13 for the Selective Catalytic Reduction of NO<i><sub>x</sub></i> with NH<sub>3</sub>

To reveal the nature of SO<sub>2</sub> poisoning over Cu-SSZ-13 catalyst under actual exhaust conditions, the catalyst was pretreated at 200 and 500 °C in a flow containing NH<sub>3</sub>, NO, O<sub>2</sub>, SO<sub>2</sub>, and H<sub>2</sub>...
