One-pot catalyst preparation:combined detemplating and Fe ion-exchange of BEA through Fenton's chemistry

摘要

BEA zeolite has been simultaneously detemplated and Fe-exchanged by treating the parent zeolite with a Fenton's-type reagent (Fe~(3+)-H_2O_2) at low temperature.This one-pot process simplifies and speeds up considerably the preparation route.The catalyst shows excellent performance on N_2O decomposition compared to conventionally prepared Fe-BEA.
