Porous Organic Frameworks for Iodine Capture and Gas Separation
This research community develops porous organic materials—specifically covalent organic frameworks, hydrogen-bonded organic frameworks, and microporous polymers—to capture iodine vapors and separate gas mixtures. The work addresses the removal of radioactive iodine and methyl iodide from air, as well as the separation of industrial gases like ethane and ethylene.
The core materials are covalent organic frameworks (COFs) and hydrogen-bonded organic frameworks (HBOFs), often synthesized with high chemical and thermal stability. Recurring applications include the efficient adsorption of iodine vapor and radioactive iodine, driven by the need for selective uptake from complex gas streams. The community also explores the use of these porous structures for methane adsorption, carbon dioxide fixation, and the separation of ethane/ethylene mixtures. Methods focus on tuning pore environments, introducing charged adsorbents, and engineering molecular linkages to enhance selectivity and capacity. While iodine capture dominates the specific application focus, the underlying material platform is applied broadly to gas separation and environmental remediation.
The largest share of the community's output is found in iodine research, accounting for 3.4% of all iodine research tracked, with 4,867 papers in this group. This is the element with the highest paper count within this community.
The community comprises 8,934 papers, publishing most frequently in the Journal of the American Chemical Society, Chemical Engineering Journal, and Angewandte Chemie International Edition.
Recent work continues to focus on iodine capture, with new studies detailing charged adsorbents and aerogel materials for trapping radioactive iodine. Other recent papers explore the use of covalent organic frameworks for photocatalytic carbon dioxide fixation and the separation of ethane and ethylene, indicating a sustained interest in both environmental remediation and industrial gas processing.
