A significant enhancement of catalytic activities in oxidation with H_2O_2 over the TS-1 zeolite by adjusting the catalyst wettability

摘要

Hydrophilic TS-1 (H-TS-1) with rich hydroxyl groups, which were confirmed by ~(29)Si and ~1H 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 H_2O_2 on H-TS-1.
