在不使用有机结构导向剂的条件下，采用微波辅助晶化法在2-3 h内成功合成了镁碱沸石。结晶温度和晶种含量是两个关键因素。在不同的时间段所采取的样品的XRD图案和SEM图像显示，在结晶过程中，晶种仅部分溶解，并且凝胶中的硅酸盐（铝）物种在部分溶解的晶种的表面上生长。提出了一种核壳型沸石分子筛的生长模型。与原始晶种沸石相比，合成的FER沸石形貌更规则，粒径更大。通过调节晶种的粒度，可以将FER晶体的尺寸控制在0.4-3.0 μm之间。微波辅助快速合成的FER对1-丁烯骨架异构化反应的催化性能与常规水热合成的FER相当。
Ferrierite (FER) zeolite has been successfully synthesized within 2–3 h through microwave assisted crystallization without using organic structure directing agent. Crystallization temperature and seed content were found to be two of the key factors. XRD patterns and SEM images of the samples taken at different periods of time revealed that seeds were only partially dissolved during the crystallization process and silicate (alumino) species in the gel grew upon the surface of the partially dissolved seed. A core-shell zeolite growth model was proposed. Compared with original seed zeolite, as-synthesized FER zeolite had more regular morphology and larger particle size. The FER crystal size could be controlled in the range of 0.4–3.0 μm by adjusting the particle size of the seeds. FER obtained through microwave assisted rapid synthesis showed similar catalytic performance in 1-butene skeletal isomerization with the FER obtained through conventional hydrothermal synthesis.
