| 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5.1nm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.

| 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 m... |
