Stable zeolites that have larger pore apertures and a three-dimensional topology are of interest because they could be used to adsorb molecules, particularly for application in oil refining. Several large-pore zeolitic materials with channels formed by openings more than 12 rings known, but all them one-dimensional channel system limits their use catalysis. We report the synthesis some characterizations IM-12, thermally stable germanium-containing zeolite contains first two-dimensional extra-large pores 14- 12-ring channels.
