Lithiated Porous Aromatic Frameworks with Exceptional Gas Storage Capacity

摘要

Gas storage has risen to prominence in recent years owing to the pressing need for solutions to mobile storage of alternative fuels, such as hydrogen or methane, and the environmental importance of capturing carbon dioxide. The use of adsorbents has opened the possibility of high volumetric and gravimetric capacities at low operating pressures for these applications. In particular, the development of metal-organic frameworks (MOFs) has been especially significant, given their high surface areas and periodic porosity, which satisfy the stipulated performance criteria for widespread application of these materials. However, many MOFs have low physiochemical stability, and others are limited in their gravimetric capacities by the presence of heavy metal ions.
