This content is a preprint and has not undergone peer review at the time of posting.


In order to circumvent the deactivation of the amorphous and mesoporous TiO2–SiO2 catalyst, we investigated the effect of surface hydrophobization on the catalyst activity in the presence of water for the epoxidation of cyclohexene.
