Porous Organic Materials for Iodine Capture and Radioactive Waste Management
This community develops porous organic frameworks, polymers, and carbon-based materials designed to adsorb and remove iodine from gas streams and aqueous solutions, primarily to manage radioactive waste and environmental contamination.
The research focuses on the synthesis and structural modification of covalent organic frameworks (COFs), metal-organic frameworks (MOFs), and conjugated microporous polymers to enhance their affinity for iodine species. Key recurring themes include the efficient capture of volatile iodine vapor and methyl iodide, as well as the removal of radioactive iodine from water. The work emphasizes tuning pore environments, surface chemistry, and material stability to achieve selective and high-capacity adsorption. Applications range from nuclear air purification and off-gas treatment to the remediation of contaminated water sources, with a strong emphasis on designing materials that can handle both elemental iodine and organic iodides.
The community is most heavily concentrated in iodine research, accounting for 2.8% of all tracked iodine studies and comprising 4,349 papers. It also appears in carbon, nitrogen, and hydrogen research, though with significantly smaller shares of less than 0.2% each.
The community includes 7,605 papers, published primarily in the Journal of the American Chemical Society, Chemical Engineering Journal, and Separation and Purification Technology.
Recent work continues to explore advanced COF architectures for iodine capture, including charged adsorbents and lignin-based nanocomposites for radioactive iodine trapping. Newer studies also examine the use of these porous materials for photocatalysis and enzyme immobilization, indicating a broadening of application scope beyond simple adsorption.
