Enhanced NH 3 -SCR activity of Cu-SAPO-34 by regulating Si distribution via an interzeolite conversion strategy

An interzeolite conversion (IZC) method was developed for the rapid synthesis of Cu-SAPO-34 from SAPO-37, achieving isolated Si distribution and optimized Cu states. The resulting Cu-SAPO-34 exhibited exceptional NH -SCR performance, with over 90% NO conversion from 200-600 °C due to proper acidity...

Description
Summary:An interzeolite conversion (IZC) method was developed for the rapid synthesis of Cu-SAPO-34 from SAPO-37, achieving isolated Si distribution and optimized Cu states. The resulting Cu-SAPO-34 exhibited exceptional NH -SCR performance, with over 90% NO conversion from 200-600 °C due to proper acidity and Cu status generated from the isolated Si.
