Chemical Storage of Hydrogen within Crystalline Metal-Organic Solids
Prof. MacGillivray has developed a solution to circumvent the issues of high pressure, high density, and surface incompatibilities encountered by previous hydrogen storage methods. This method uses a crystalline metal-organic solid as a reactive, low-density storage material for hydrogen. This material includes transition-metal-ions assembled with organic ligands that bridge the metals together into porous structures with very low densities. Given hydrogen’s ability to react with both transition-metal-ions and organic groups, the pores of metal organic frameworks are capable of storing and releasing hydrogen gas. The crystalline solid possesses internal pores of size and shape suitable for effectively entrapping and reacting reversibly with hydrogen. Such a reaction can facilitate the storage and release of hydrogen through dissociation and re-association of the atoms of the molecule.
