## Description

- description: Early hydrothermal degradation of Cu-SSZ-13 and Cu-SSZ-39 zeolites
    with similar Cu content was investigated. Electron ptychography revealed the Cu
    occupancy at the eight-membered ring sites of Cu-SSZ-39 is lower than that of
    Cu-SSZ-13, clearly demonstrating that the former is more stable than the latter
    under hydrothermal aging conditions.
