| Popis: | Using a photo-assisted deposition method, a tetrahedrally coordinated chromium oxide moieties (tetra-Cr oxide) can be anchored on a tetrahedrally coordinated titanium oxide moieties (tetra-Ti oxide) included within a framework of mesoporous silica. Under UV-light irradiation, the tetra-Cr oxide moieties can be deposited on the photo-excited tetra-Ti oxide moieties forming a direct interaction. This catalyst can demonstrate as a photocatalyst having the high efficiency and the high selectivity in the photoepoxidation of propene with O2 under visible light irradiation.
