- EU-7 zeolite with Si/Al ratio of 15 is identified as a BIK type zeolite. The framework charge is compensated with Cs⁺ cations located in 8-ring channels at regular distances. Even partially exchanged, Cu-loaded EU-7 is active in NH₃-SCR and withstands hydrothermal aging at 900 °C needed for application in diesel particulate filters.
