arrangements and circular 36-ring pores. The structure is further validated by atomic-resolution real-space imaging using electron ptychography. JU-69 exhibits thermal stability up to 900 °C and periodically arranged silanol groups that enable efficient metal anchoring, demonstrated by active Pd/JU-69 catalysts for bulky molecule hydrogenation. This work establishes a pathway for designing crystalline mesoporous zeolites with unprecedented structural openness.
