Physical Sorption of Molecular Hydrogen by Microporous Organic Polymers
The present work describes crosslinked and hypercrosslinked polymers viewed as high surface area materials to adsorb a large amount of molecular hydrogen. Crosslinked polyaniline and polypyrrole were used as examples of hydrogen adsorption by microporous organic polymers. The main reason for physical sorption happening in microporous organic polymers as well the challenges on the way to adjusting the value of hydrogen adsorption enthalpy within the range of 15-20 kJ•mol–1 H2 are highlighted.
