Pyrolysis and patterning of Acetobacter xylinum cellulose for hydrogen storage
by O'Brien, Brendan, M.S., Tufts University, 2009, 140; 1468279
Abstract (Summary)

The storage of hydrogen poses numerous technological challenges. Hydrogen gas has one of the highest chemical energy densities per weight of any chemical or compound. However, hydrogen's volumetric density is also one of the lowest. To this end the storage capacities of nanostructured carbon have been the matter of considerable research. In this study attempts are made to produce a storage medium for hydrogen gas that relies upon the Van der Waals forces present in carbon structures, in particular carbon nanofibers (CNFs) and amorphous carbon. In this research carbon nanofibers are derived from the thermal processing of bacterial cellulose. The bacterial cellulose (BC) is also considered as a candidate for microscale patterning in an attempt to improve the real-world storage capabilities of the carbon nanofibers by decreasing the torturous path of the H2.
