Post-synthesis and catalytic performance of FER type sub-zeolite Ti-ECNU-8

Titanosilicate Ti-ECNU-8 with a FER type sub-zeolite structure was post-synthesized by structural reorganization of layered silicate PLS-3 followed by solid-gas titanation with TiCl4 vapor. With an exposed external surface, Ti-ECNU-8 turned out to be an active oxidation catalyst for the epoxidation of cycloalkenes with hydrogen peroxide.
