Abstract

Treatments of ETS-10 titanosilicates with HCl, NH₄Cl or citric acid led to the change in the coordination environment of Ti. These treatments also led to the partial extraction of Ti from the framework of ETS-10. The local structural changes brought about the formation of the active sites for the epoxidation of cyclohexene with H₂O₂. The highest epoxidation activity and efficiency of H₂O₂ as an oxidant were achieved when the original [Na, K]-type ETS-10 was treated with 3.7 moldm^-3 NH₄Cl solution followed by the calcination at 723 K.
