Ti-MCM-41 catalysts were prepared
incorporating Ti by post-synthesis methods: wetness and wet impregnation of
MCM-41 mesoporous solid. The samples were characterized by XRD at low angle, UVvis
DRS, Raman spectroscopy, BET, ICP and colorimetry. The results were compared with
those obtained for Ti-MCM-41 hydrotermically prepared. All catalysts were
tested in the limonene epoxidation with H2O2. Three kinds of
Ti sites were observed in post-synthesis catalysts which were different from
that found in the hydrothermal Ti-MCM-41. These structural differences do not
produce important changes in the catalytic activity, instead a slight decrease
in the epoxide selectivity can be observed. The catalysts prepared by
post-synthesis methods are promising in the limonene epoxidation with H2O2 since these methods are simple and reproducible.
