- A novel nanostructured carbon was prepared using Ti-SBA-15 as hard template.
- Novel Ti-CMK-3 displays very high dispersed TiO2 species.
- The obtained Ti-CMK-3 exhibited significantly enhanced H2 storage properties (2.6Â wt%).
This work deals with the development of a novel procedure to synthesize titania-modified nanostructured carbon employing Ti-SBA-15 as hard template. The new mesoporous carbon displays high specific surface area of 1044Â m2/g and large pore volume of 0.7Â cm3/g. XRD pattern of Ti-CMK-3 indicates that the ordered structure of this material is similar to the CMK-3. XRD, XPS and UV-Vis-DRS analysis indicated that Ti is highly dispersed as anatase phase in Ti-CMK-3. The synthesized Ti-CMK-3 exhibited significantly enhanced H2 storage properties (2.6Â wt%, equivalent to 13Â mmol/g) compared with CMK-3 without Ti (2.2Â wt%, 11Â mmol/g) at 77Â K and 10Â bar.
