Production of hydrogen

Metal Organic Frameworks - MOF Compared to traditional

zeolites and porous carbon materials, MOFs have very high number of pores and surface area which allow higher hydrogen uptake in a given volume. Thus, research interests on hydrogen storage in MOFs have been growing since 2003 when the first MOF- based hydrogen storage was introduced.

Hydrogen Storage in Carbon Nanotubes • Hydrogen storage in carbon nanotubes is a recent topic

of research and may be an important step towards making mobile hydrogen storage feasible.

• How to stop the hydrogen in the tube? • Physisorption • Chemisorption

Carbon Nanotubes • Carbon nanotubes (CNTs) essentially consist of sheets of

graphite rolled into seamless tubes and capped at the ends. There are two forms CNTs take: single-walled and multi-walled. As the name implies,

• singled-walled nanotubes (SWNT) are composed of a single sheet of graphite; a diameter range of 0.4 to > 3nm is common.

• Multiwalled nanotubes (MWNT) are composed of several sheets, arranged concentrically in increasingly larger diameters with diameters in the range of 1.4 to 100 nm.

• Due to their diminutive dimensions, CNTs have unique physical and electrical properties. These include ultra high thermal conductivities (>3000 W/m-K), a Young’s modulus of ≈0.64 TPa, and the elastic ability to extend ≈5.8% of its original length before breaking.

• More appealing still is the disproportionately large surface area to volume that these materials possess, for this allows for a greater potential of interactions, whether they be physical or chemical in nature. Also, consider that their dimensions are relative to those of atoms and molecules. This increases the strength that these interactions have between one another, particularly from Van der Waals forces.
