摘要
中孔沸石晶体因其同时具有中孔材料和沸石晶体的双重优点而备受关注。综述了碳纳米材料、碳气凝胶聚合物、阳离子聚合物、有机硅烷以及纳米无机材料几种不同模板剂制备中孔沸石的路线,讨论了不同模板剂与硅铝酸盐凝胶-溶胶体系间的相互作用对制备高催化性能中孔沸石的影响,并对中孔沸石未来的发展进行了展望。
Zeolites with intracrystal mesopores have been paid much attention recently due to the combination of the advantages of mesoporous materials and zeolite crystals.This review describes the synthetic routes for preparation of mesoporous zeolites by various templates including nanostructured carbons,carbon and polymer aerogel,cationic polymers,organosilanes and nanosized inorganic materials.The interaction between these mesoscale templates with silica or aluminosilicate species in the starting sol-gels has been discussed.Furthermore,the future development of excellent catalytic properties over these mesoporous zeolites are systemically summarized and prospected.
