Hydrogen storage templated carbons

The obtained experimental results indicate that the hydrogen uptake at 77 K and 0.1 MPa in the silica mesoporous molecular sieve, MCM-41, is very low [147], Nevertheless, MMS have been used as templates for the creation of ordered porous carbon with tailored pore sizes, which can be applied in hydrogen storage [158],...

Over the last 2 decades, there has been an increasing interest in the development of one-dimensional nanomaterials, such as carbon nanotubes (Ounaies et al., 2003), bacterial nanofibers (Yano et al., 2005), silica nanotubes (Miyaji et al., 2003), and titanium dioxide nanotubes and nanowires (Yuan and Su, 2004). These new materials have relatively large specific surface areas and high aspect ratios hence, they are suitable for use as reinforcements, chemical probes, sensors, hydrogen storage, displays, and templates. One-dimension material/polymer nanocomposites allow us to take advantage of the extraordinary properties of one-dimension nanomaterials. 

Taking into account that such a perfect correlation with the ultramicropore volume is not so well observed for all kinds of porous carbons [131], it is once more obvious that the electrochemical performance for hydrt en storage is strongly controlled by the presence of mesopores connected to the microporcs. The mesopores are essential to Teed the micropores with hydrated ions or water molecules which will be further reduced giving hydrogen able to be fixed in the ultramicropores. A direct evidence of the beneficial effect of mesopores has been demonstrated by the carbonization of sucrose in the SBA-15 template...
