摘要:

具有CHA拓扑结构的SAPO-34分子筛因其适宜的酸性、较好的抗积碳性能和优异的水热稳定性等优点,已广泛应用于诸多催化反应中。先对常规SAPO-34分子筛的合成方法进行简单介绍,并针对SAPO-34分子筛的一些新型合成策略如纳米化、多级孔结构调控等进行了详细介绍,对纳米SAPO-34分子筛和多级孔SAPO-34分子筛合成方法的原理和特点进行了梳理;之后介绍了影响SAPO-34分子筛合成的多种因素,包括原料组成与配比、模板剂和晶种的选择及晶化条件等,详细讨论了这些因素对SAPO-34分子筛的结晶度、晶体形貌和晶粒尺寸等方面的影响;然后对SAPO-34分子筛在甲醇制烯烃(MTO)、氨选择性催化还原氮氧化物(NH3-SCR)等催化反应中的实际应用进行了介绍;最后对进一步实现SAPO-34分子筛的绿色和高效合成进行了展望。

Abstract:

The SAPO-34 molecular sieve,owing to its CHA topology,moderate acidity,excellent anti-coking properties,and superior hydrothermal stability,has been widely employed in various catalytic reactions.The synthesis methods of SAPO-34 molecular sieves were introduced briefly.Novel synthesis strategies such as nano-sizing and hierarchical pore structure regulation were introduced in detail.The principle and characteristics of the synthesis methods of nano SAPO-34 molecular sieve and hierarchical porous SAPO-34 molecular sieve were summarized.Subsequently,the factors influencing the synthesis of SAPO-34 molecular sieves were discussed,including precursor composition and ratio,structure-directing agents,seeds and crystallization conditions,all of which collectively affect crystallinity,crystal morphology,and particle size.Furthermore,the practical applications of SAPO-34 molecular sieves in catalytic reactions such as methanol-to-olefins(MTO) and selective catalytic reduction of nitrogen oxides with ammonia(NH3-SCR) were reviewed.Finally,prospects for achieving greener and more efficient synthesis of SAPO-34 molecular sieves were outlined.
