Structure Elucidation of the Highly Active Titanosilicate Catalyst Ti‐YNU‐1

Between the sheets: The structure of the titanosilicate Ti-YNU-1 reveals a much larger spacing along the c axis between the MWW sheets than its lamellar precursor and 3D Ti-MWW (see picture). Formation of twelve-membered rings would explain this cell expansion, which results in increased steric accessibility and may explain the higher catalytic activity of Ti-YNU-1 relative to other titanosilicates.
