摘要
本文主要阐述了分级孔沸石材料的合成、表征及其催化应用的最新进展。基于分级孔的产生机制,系统地评述了分级孔沸石材料合成方法,包括水热处理、化学处理、酸浸法、碱浸法以及模板剂法,重点对模板剂合成法进行了分类阐述,进而对分级孔沸石材料的结构鉴定、织构性能、水热稳定性及酸性测定相关的表征方法进行了综述;最后结合实例说明了分级孔沸石材料在催化反应中的应用前景。
This article mainly covers the recent development of synthesis, characterization and catalytic applications of hierarchical pore zeolite materials. Based on mechanisms of hierarchical pore formation, synthetic approaches of hierarchical pore zeolite materials including hydrothermal and chemical treatments, acid leaching, base leaching, and templating are systematically reviewed, especially, categorizing the synthetic method of templating. The relevance of characterization techniques for analysis of hierarchical pore zeolite materials, i.e., their structure, texture, hydrothermal stability, and acid properties are subsequently described. Finally, the applications of hierarchical pore zeolite materials as catalysts to acid-catalyzed reactions, environmental catalysis, oxidation reactions and synthesis of fine chemicals are focused, providing guide for the potential of hierarchical pore zeolite materials in catalytic applications.
