摘　　要：ＸＲＤ，ＩＲ，２９ＳｉＭＡＳＮＭＲ，ＵＶ－ＶＩＳ及ＸＰＳ能谱表征证实钛原子进入了钛－硅五元环沸石的骨架晶格位（不含铝）．ＴＧ－ＤＴＡ结果表明，钛原子进入沸石骨架导致沸石骨架的热稳定性提高，超过１４７３Ｋ．氯丙烯与Ｈ２Ｏ２（３０％）的环氧化反应结果表明钛－硅沸石具有优异的氧化性能，这也从另一个侧面证实了钛原子位于沸石骨架晶格位．he structure and catalytic property of titanosilicate zeolite(no Al)were studied by XRD, IR, 29Si HASNER,UV-VIS spectra and XPS energy spectrum. The characterization verified that Ti atoms were present in the framework lattice of zeolite. TG-DTA results showed that the thermal stability of Ti-Si .zeolite framework was over 1473 K. On the other hand,TS-1 and TS-2 zeolites possessed excellent catalytic oxidation property. Both of them could catalyze the epoxidation reaction of allylchloride using hydrogen peroxide(30%)as oxidant.It also confirmed that Ti atoms had been incorporated into the framework of zeolite.
