摘要:

片层丝光沸石在特定取向上具有更短的长度,表现出优异的催化性能成为研究热点。本文综述了目前报道的片层丝光沸石原位合成方法,包括单模板法、双模板法以及调整合成条件等,对其在羰基化、环化以及MTO催化反应进行了具体分析,并指出双模板法相比于单模板法从成本和合成方法角度更具优势,结合理论计算对模板剂的定向设计和机理探讨,以合成特定取向且介孔性良好的丝光沸石为模板法的发展方向。合成因素的调整对取向长度的控制较为有效,但一般仍需与特定模板的协同。在应用领域,沿b轴和c轴取向的片状丝光沸石在特定反应中表现出更好的催化活性。从宏观上,建立取向长度比例与特定反应之间的关系;从微观上,结合理论计算和先进表征技术研究模板剂与酸分布和催化反应的相关性,将是片层丝光沸石的研究重点。

Abstract:

Lamellar mordenite has become a research hotspot due to its excellent catalytic performance by the short orientation length. In this paper, the in-situ synthesis methods of lamellar mordenite, including single template method, double template method and adjusting synthetic factors, are reviewed, and their catalytic performance in carbonylation, cyclization and MTO reactions is analyzed. It also indicates that double template method has more advantages than single template method from the perspectives of cost and synthetic method. Using theoretical calculation to explore the directional design and mechanism of template agents, the development direction of template method is to synthesize specific oriented and well mesoporous mordenite. The adjustment of synthetic factors is effective in controlling the orientation length, but it still needs to be compatible with specific templates. In the applications, lamellar mordenite oriented along the b-axis and c-axis has shown good catalytic activity in specific reactions. On a macro level, the relationship between the orientation length ratio and specific reactions should be established. On the micro level, the research on lamellar mordenite focuses on the correlation between the template and acid distribution and catalytic reactions by theoretical calculation and advanced characterization technologies.

Key words: mordenite, orientation length, synthesis method
