    摘要: There is disclosed a method of making, through direct synthesis, a catalyst comprising an Fe-SAPO-34 molecular sieve. There is also disclosed an Fe-SAPO-34 molecular sieve made according to the disclosed method herein, wherein the molecular sieve contains both framework iron and iron cations at ion-exchange sites. In addition, there is disclosed a method of using the Fe-SAPO-34 disclosed herein in a selective catalytic reduction reaction, typically in the presence of ammonia or urea, to reduce or remove nitric oxides from exhaust emissions.
