Resumen:
This work deals with adevelopment of a novel procedure to synthetized nanostructured carbon modified with highly dispersed titania in the anatase phase,employing Ti-SBA-15 as hard template. The new mesoporous carbon displays a high specific surface area of 1044 m2/g, a large pore volume of 0.7 cm3/g. XRD pattern of Ti-CMK-3 indicate that ordered structure of this material is similar to the CMK-3. XRD, XPS and UV-Vis analysis indicated that Ti is as anatase phase in Ti-CMK-3. The synthesized Ti-CMK-3 exhibited significantly enhanced H2 storageproperties (2.6 wt.%) compared with CMK-3 without Ti (2.2 wt.%) at 77K and 10 bar.
