Organotemplate-free synthesis of high-silica ferrierite zeolite induced by CDO-structure zeolite building units

摘要

We have demonstrated here for the first time that high-silica fer-rierite zeolite, designated as ZJM-2, is successfully synthesized by an induction of CDO-structure zeolite building units in the absence of organic templates. The resulting ZJM-2 has good crystallinity, high surface area, similar crystals shape, only tetrahedral Al~(3+) species, and abundant acidic sites.
