Preparation method of flaky mordenite molecular sieve

The invention discloses a preparation method of a flaky mordenite molecular sieve, which comprises the following steps of: mixing a zeolite molecular sieve precursor, an alkali source, water and an additive, and crystallizing under a hydrothermal condition to obtain a product, and is characterized in that the zeolite molecular sieve precursor has flaky morphology. The crystal zone axis of the synthesized mordenite molecular sieve is in the c-axis direction, namely the [001] direction, the thickness in the c-axis direction is 5-100 nm, the plane size in the ab axis is 200-5000 nm, and the twelve-membered ring one-dimensional straight pore channel is in the c-axis direction. 本发明公开了一种片状丝光沸石分子筛的制备方法，是将沸石分子筛前驱体、碱源、水、添加剂混合，在水热条件下晶化得到产品，其特征在于：所述沸石分子筛前驱体具有片状形貌。合成得到的丝光沸石分子筛的晶带轴为c轴方向，即[001]方向，沿c轴方向厚度为5～100nm，沿ab轴平面尺寸为200～5000nm，其十二元环一维直孔道为c轴方向。
