Novel preparation of CMK-3 nanostructured material modified with titania applied in hydrogen uptake and storage

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 1044 m2/g and large pore volume of 0.7 cm3/g. XRD pattern of Ti-CMK-3 indicates that t...

Summary: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 1044 m2/g and large pore volume of 0.7 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 (2.6 wt%, equivalent to 13 mmol/g) compared with CMK-3 without Ti (2.2 wt%, 11 mmol/g) at 77 K and 10 bar. [Display omitted] •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 (2.6 wt%).
