Is MCM-41 really advantageous over amorphous silica? The case of grafted titanium epoxidation catalysts

Abstract

MCM-41 can be used in the same way as amorphous silica for the preparation of supported titanium catalysts; MCM-41 does not show clear advantages over silica in epoxidation reactions with either TBHP or H₂O₂; only in one case is a positive effect observed and this involves the recycled catalyst with H₂O₂.
