摘要/Abstract

摘要： 以一种多功能长链有机硅为唯一硅源合成了多级孔材料SAPO-34-H(Hierarchical), 并对其结构和性质进行了表征. 氮气吸附和透射电镜(TEM)照片显示, SAPO-34-H样品不仅拥有常规的微孔体系, 还有孔径在5.1 nm左右的介孔体系. 氨气程序升温脱附表征(NH₃-TPD)结果显示, 与传统的SAPO-34相比, 该材料在引入介孔的同时酸性有所降低.

关键词: SAPO-34多级孔材料, 微孔, 介孔

Abstract: Silicoaluminophosphate zeolite SAPO-34 exhibits excellent performance in adsorption and catalysis due to its unique structure and small diameter. Mesoporous SAPO-34(named as SAPO-34-H) was prepared using a long\|chained organosilane as the only source of silicon and the mesoscale template. SAPO-34-H was characterized by various techniques. N₂ adsorption and TEM images results show that mesopores with a diameter of ca. 5.1 nm exist in the microporous crystals. NH₃-TPD results show that the introduction of mesopores results in the decrease of acidity.

Key words: Hierarchical porous material(SAPO-34-H), Micropore, Mesopore
