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

BEA zeolite has been simultaneously detemplated and Fe-exchanged by treating the parent zeolite with a Fentonʹs-type reagent (Fe3+–H2O2) at low temperature. This one-pot process simplifies and speeds up considerably the preparation route. The catalyst shows excellent performance on N2O decomposition compared to conventionally prepared Fe-BEA.
