综述了近几年国内外多级孔分子筛的研究进展,重点介绍了“自上而下”和“自下而上”两大类合成方法,并进一步阐述了脱硅法、重结晶法、硬模板法、软模板法、无模板自组装等具体合成方法的优势及局限性,同时介绍了不同方法制得的多级孔分子筛的催化应用,最后对多级孔分子筛的发展前景进行了展望。 In this paper, the progress of research on multistage pore molecular sieves at home and abroad in recent years is reviewed. The synthesis methods of “top-down” and “bottom-up” are introduced emphatically, and the desiliconization method, Crystallization method, hard template method, soft template method, template-free self-assembly method and other specific advantages and limitations of synthetic methods, and at the same time introduces the different methods of preparation of multi-stage molecular sieve catalytic applications, and finally the development of multi-stage molecular sieve pore prospects Prospects.
