摘要
SSZ-13分子筛因其有序孔道结构、大比表面积、高催化活性、良好水热稳定性等,近年来被广泛应用于催化合成、环境保护、新能源等多个领域。首先,介绍了水热合成法、固相研磨法、干胶转换法等SSZ-13分子筛合成方法,并指出了各自优缺点;其次,针对目前SSZ-13分子筛普遍存在积炭能力弱、催化活性不高的问题,介绍了孔道结构和晶粒尺寸等优化调控方法;再者,从模板剂的使用、合成条件、晶种等方面,阐述了降低SSZ-13分子筛合成成本和提高合成效率的调控方法。在此基础上,提出了开发绿色、环保、低成本、高效率的新型SSZ-13分子筛合成方法,而面向不同领域的多功能新型SSZ-13分子筛是当前迫切需要解决的问题。
SSZ-13 zeolite has been widely used in many fields in recently years such as catalytic synthesis,environmental protection and new energy fields because of its ordered pore structure,large specific surface area,high catalytic activity and good hydrothermal stability.First,some conventional synthesis methods of SSZ-13 zeolite were summarized,including hydrothermal synthesis,solid grinding and dry-gel conversion,and the advantages and disadvantages of these synthesis methods were discussed.Then,owing to the low carbon deposition resistance and low catalytic activity of SSZ-13 zeolite,the optimization methods of pore structure and grain size were reviewed.In addition,the controlling methods for decreasing the synthesis cost and improving the synthesis efficiency of SSZ-13 zeolite were described from the aspects of templates,synthesis conditions and seeds etc.The green SSZ-13 zeolite synthesis method with low cost and high efficiency was proposed,and the new multi-functional SSZ-13 zeolites for different fields are urgently needed.
