Abstract
The present invention is directed to a method of preparing a molecular sieve of SWY framework type, denominated STA-30. STA-30 is synthesized using 1,4-diazabicyclo[2.2.2]octane, 1-azabicyclo[2.2.2]octane derivates and combinations thereof as structure directing agents. The resulting molecular sieve is useful as catalysts, particularly when used in combination with exchanged transition metal(s) for the Selective Catalytic Reduction (SCR) of NO.
