Selective catalytic reduction of NO with NH3 over HZSM-5-supported Fe-Cu nanocomposite catalysts: The Fe-Cu bimetallic effect

- The bimetallic nanocomposite Fex-Cu4/ZSM-5 catalysts were firstly synthesized.
- Fe4-Cu4/ZSM-5 catalysts exhibited the high NO conversion (>90%) among the wide temperature range.
- The interaction between iron and copper species was investigated.
- A high ratio of Fe2+/Fe3+ was found in favor of NH3-SCR reaction.
