Multiroute Synthesis of Porous Anionic Frameworks and Size-Tunable Extraframework Organic Cation-Controlled Gas Sorption Properties

摘要

Porous materials are of great interest as adsorbents for applications such as hydrogen storage and carbon dioxide sequestration. In efforts to develop better porous metal-organic framework (MOF) materials for such applications, a number of structural features such as pore size and shape, surface area, and pore volume have been found to play important roles in the sorption energetics and uptake capacity. Studies have also shown that a large pore size is not necessarily advantageous for storing small gas molecules. For example, an increase in the pore size can lead to a decrease in the volumetric H_2 uptake.
