NMR Signatures and Electronic Structure of Ti Sites in Titanosilicalite-1 from Solid-State Ti-47/49 NMR Spectroscopy
(2023)Journal of the American Chemical SocietyAlthough titanosilicalite-1 (TS-1) is among the mostsuccessfuloxidation catalysts used in industry, its active site structure isstill debated. Recent efforts have mostly focused on understandingthe role of defect sites and extraframework Ti. Here, we report the Ti-47/49 signature of TS-1 and molecular analogues [Ti(OTBOS)(4)] and [Ti(OTBOS)(3)((OPr)-Pr- i )] using novel MAS CryoProbe to enhance the sensitivity. Whilethe dehydrated TS-1 ...Journal Article
