Silicate material ZEO-2 and silicate molecular sieve ZEO-3 and synthesis method therefor and use thereof

Abstract

The present invention relates to a one-dimensional silicate material ZEO-2 with a novel structure and a three-dimensional silicate molecular sieve ZEO-3 obtained by roasting ZEO-2 and a synthesis method therefor and a use thereof. The X-ray powder diffraction characteristics and crystal structures of the two silicate materials are represented. The one-dimensional silicate ZEO-2 can be synthesized by a simple method. The molecular sieve ZEO-3 can be obtained by calcining the one-dimensional silicate ZEO-2 to cause topological condensation. ZEO-2 can be used as a silicon source or a precursor in the synthesis of a novel molecular sieve. The molecular sieve ZEO-3 has good thermal stability and can be used as an adsorbent or a catalyst.
