Speciation, Structural Refinement, and Distribution of Ti Sites in Titanium Silicalite‐1 From 47/49Ti NMR Crystallography at 28.2 Tesla Titanium silicalite-1 (TS-1), used in industrial selective oxidation processes, depends on specific, yet still unresolved Ti sites, dispersed within the framework of an MFI-zeolite. Applying high fie....

47/49Ti NMR Crystallography enables to refine the speciation, distortion and distribution of Ti sites in Titanium Silicalite-1, a prominent catalyst for sustainable selective oxidation reactions

Deciphering Active Sites in Titanium Silicalite-1 via Solid-State NMR and X-ray Spectroscopic Signatures ConspectusPropylene oxide manufacturing has experienced one of the fastest growth rates of commodity chemicals in recent years (ca. 21% from 2020 to 2023) and is expected to reach a market size of 36 ...

Rising propylene oxide production intensifies interest in TS-1 and other Ti-zeotype catalysts. New ssNMR and XAS insights into Ti-site structure, peroxo intermediates, defect roles, and hydration effects are advancing molecular-level control over catalyst design.
