A significant enhancement of catalytic activities in oxidation with H2O2 over the TS-1 zeolite by adjusting the catalyst wettability

Hydrophilic TS-1 (H-TS-1) with rich hydroxyl groups, which were confirmed by Si-29 and H-1 NMR techniques, exhibits much higher activities in the oxidation than conventional TS-1. This phenomenon is strongly related to the unique features of high enrichment of H2O2 on H-TS-1.
