| 英文摘要 | Zeolite synthesis in contemporary chemical industries is predominantly conducted using organic structure-directing agents (osdas), which are chronically hazardous to humans and the environment. it is a growing trend to develop an eco-friendly and nuisanceless osda for zeolite synthesis. herein, choline is employed as a non-toxic and green osda to synthesize high silica y zeolite with sio2/al2o3 ratios of 6.5-6.8. the prepared y zeolite samples exhibited outstanding (hydro)thermal stability at ultrahigh temperature owing to the higher sio2/al2o3 ratio. the xrf, sem, si-29-nmr and na-13+ results suggested that choline plays a structure-directing role in the synthesis of y zeolite, while the feed molar fraction of na+ is a crucial determinant for the framework sio2/al2o3 ratio and the crystal morphology.
