Implication

Experimental study demonstrates high-capacity hydrogen adsorption in graphite nanofibers under ambient temperatures, suggesting viable next-generation fuel storage solutions.

Key Points

To evaluate the hydrogen sorption, retention, and release capacities of specially structured graphite nanofibers under ambient temperature conditions.
Synthesized graphite nanofibers consisting of 30–500 Å wide graphite platelets through the catalytic dissociation of carbon-containing gases over select metal surfaces.
Exposed the nanofiber materials to molecular hydrogen gas at 120 atm and 25 °C, followed by pressure reduction to near-atmospheric levels to observe gas desorption.
Graphite nanofibers sorbed and retained in excess of 20 L (STP) of hydrogen per gram of carbon at 120 atm and 25 °C, exceeding conventional storage systems by over an order of magnitude.
Slit-shaped nanopores with 3.37 Å interplanar spacing expanded across flexible van der Waals boundaries to support multilayer sorption of hydrogen molecules (2.89 Å kinetic diameter).
Lowering the pressure back to near-atmospheric conditions resulted in the release of the major fraction of stored hydrogen at room temperature.
