A beautiful dandelion-like microspheric SUZ-4 zeolite was created by the addition of ethyl acetate and using industrial by-product silica fume (SF) as silica source. The morphology of the SUZ-4 zeolite can be transformed from traditional rod to dandelion-like by adjusting the ethyl acetate dose and the pre-crystallization time of the synthesis gel. The effect of the ethyl acetate on the peculiar morphology formation and the construction mechanism were proposed as follow: Under the influence of ethyl acetate, the template in the system does not work, and the nuclei formed during the pre-crystallization are more liable to assemble in “tip-to-tip” orientation to form spheres, instead of growing on the facet with low density to form dispersed rods without ethyl acetate. On the other hand, the microscopic analyses indicated that, the dandelion-like microspheres are formed by the aggregation of little SUZ-4 crystals, which are not dense, allowing access to their interiors. Hence, the dandelion-like SUZ-4 zeolite displayed much better adsorption ability for methylene blue in water, compared with the rod-like one.

通过添加乙酸乙酯并使用工业副产品二氧化硅烟气（SF）作为二氧化硅源，可以生成美丽的蒲公英状微球SUZ-4沸石。通过调节乙酸乙酯的用量和合成凝胶的预结晶时间，可以将SUZ-4沸石的形态从传统的棒状转变为蒲公英状。提出了乙酸乙酯对特殊形貌形成的影响和构建机理：在乙酸乙酯的影响下，体系中的模板不起作用，且在预结晶过程中形成的核更易于组装。以“从尖端到尖端”的方向形成球体，而不是在低密度的小面上生长以形成不含乙酸乙酯的分散棒。另一方面，微观分析表明，像蒲公英一样的微球是由小的SUZ-4晶体聚集而成的，这些晶体不致密，可以进入其内部。因此，与棒状SUZ-4沸石相比，蒲公英型SUZ-4沸石对水中的亚甲基蓝具有更好的吸附能力。
