Studies on the Design and Development of Gas Storage Materials
As the world gradually runs out of conventional energy resources such as petroleum
and coal, the
use of innovative resources is likely to increase. In this context hydrogen-based fuel cells are
promising solutions for the efficient and clean delivery of electricity. However, storing of
hydrogen in an economic way is a major challenge. Due to the importance of hydrogen storage
(H-storage), several materials have been developed for this purpose. These include metal hydrides,
complex hydrides, chemical hydrides, zeolites, clathrates, activated carbons, fullerenes, nanotubes,
graphenes, porous materials which include metal organic frameworks (MOF), covalent organic
frameworks (COF), zeolitic imidazolate framework (ZIF), metal organic polyhedra (MOP), porous
aromatic frameworks (PAF), etc. Although MOFs and MOPs are promising candidates for
hydrogen storage, their adsorption capacities are yet to meet the U.S. Department of Energy (DOE)
targets for practical applications. To improve the storage capacities of these porous materials, an
attempt has been made to design and develop new linkers for MOF and MOP materials using
electronic structure calculations and classical Grand Canonical Monte Carlo (GCMC) simulation.
