Microporous Ti-Si Molecular Sieve TS-1

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 heterogenous catalysts; a redox sieve makes it possible to get a significantly higher selectivity to primary oxidation products. TS-1 has unique properties as a heterogenous 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 Materials carries TS-1 that was prepared using the hydrothermal method. Quantities are available in sizes ranging from 50g to 100kg; contact our customer service representatives to let us know what you need. Our products are trusted by researchers and engineers worldwide for meeting the highest standards of excellence.

3. Application Fields

Titano silicalite TS-1 has attracted attention due to its excellent catalytic properties in partial oxidation of many organic compounds‚ including:

1)     Alkene epoxidation

2)     Cyclohexanone ammoxidation

3)     Alcohol oxidation

4)     Oxidation of saturated hydrocarbon

5)     Hydroxylation of aromatic hydrocarbons



1. What is the source of H+ in the Type A of TS-1?

H+ comes from an organic amine contained in the raw material.

2. Is the pH of TS-1 neutral?

Yes, TS-1 is neutral.
