Titanium Silicalite-1 (TS-1)
Microporous Ti-Si Molecular Sieve, TS-1
Product Detail
ACS Material Titanium Silicalite-1 (TS-1) is a microporous Ti-Si molecular sieve supplied as a powder in the H+ form, with a SiO2/TiO2 molar ratio of ≥25, a BET surface area of 360–420 m²/g and a pore diameter of ~0.5 nm. It is calcined and ready to use directly.
Overview
Titanium Silicalite-1, TS-1, was the first framework-substituted redox molecular sieve to be identified. Redox molecular sieves offer a significant advantage over standard heterogeneous catalysts; a redox sieve makes it possible to get a significantly higher selectivity to primary oxidation products. TS-1 has unique properties as a heterogeneous catalyst when H2O2 is used as the oxidant and H2O2 is attractive for industrial applications because of its relatively low cost and because it is clean.
ACS Material TS-1 is prepared using the hydrothermal method. Powder (Type B), 20–50 µm, is currently available; Powder (Type A), 0.3–0.5 µm, has been discontinued, and its specifications are kept on this page for reference.
