Abstract：

In　this　article,　we　report　a　one-pot　synthesis　strategy　to　directly　synthesize　the　hierarchical　FeCu-ZSM-5　zeolite.　Its　physicochemical　properties　were　studied　by　various　characterization　techniques　and　catalytic　performance　was　tested　in　selective　catalytic　reduction　(SCR)　of　NO　with　NH3　as　reductant.　The　characterization　results　show　that:　compared　with　three　reference　zeolites　Fe/ZSM-5,　Cu/ZSM-5,　and　Fe/Cu/ZSM-5　prepared　through　an　incipient　wetness　impregnation　method,　the　synthesized　FeCu-ZSM-5　zeolite　exhibits　hierarchical　micro-mesoporous　structures,　more　Fe3+　in　zeolite　framework,　and　larger　isolated　Cu2+　species.　Therefore,　when　used　as　a　catalyst　in　NH3-SCR,　the　resulting　hierarchical　FeCu-ZSM-5　catalyst　shows　better　catalytic　performance　(high　NO　conversion　and　N2　selectivity)　in　a　wide　temperature　window　and　higher　hydrothermal　stability　than　the　three　reference　catalysts.　Our　work　provides　a　simple　and　facile　route　to　prepare　the　promising　NH3-SCR　catalyst　for　practical　applications　in　controlling　NOx　emissions.　©　2019　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim
