High‐Silica Ferrierite Zeolite Self‐Transformed from Aluminosilicate Gel

Abstract

Perfectly built zeolites: Ferrierite (FER) zeolite, with the perfect crystal structure and the same preferential orientation as siliceous FER zeolite, is synthesized by the self transformation of the amorphous seeded dry gel with a novel vapor phase transport (VPT) method in the mixed vapor of tetrahydrofuran and water.
