A robust thorium–organic framework as a bifunctional platform for iodine adsorption and Cr(vi) sensitization

Abstract

Simple synthetic modulation based on thorium nitrate and tris((4-carboxyl)phenylduryl)amine (H3TCBPA) gives rise to a new thorium-based metal-organic framework, Th-TCBPA, which features excellent hydrolytic and thermal stabilities. Incorporating electron-rich TCBPA3− linkers...

Impact of Conformational Isomerism in Two Zn-MOFs on the Multimedia Incarceration of Iodine: In-Depth Experimental and Computational Assessments

“…In all the above-mentioned cases, surface as well as inclusion-based iodine transfer is likely to occur even with a less porous nature of the framework . From the results of multiphase iodine transfer studies conducted with 1 and 2 , it can be inferred that the uptake values in this work are better than many MOFs, POPs, and zeolites (Table S1) − ,− For instance, the values of vapor phase iodine mass transfer for a T -SCNU-Z6 and a W -SCNU-Z6 are 2.05 g g –1 and 5.04 g g –1 , respectively, whereas, those for HSB-W8 and Co-IPT-IBA are 2.32 g g –1 , and 2.88 g g –1 , respectively. Compared to this, ionic iodine transfer studies in the aqueous phase are rare.…”

“…MOFs are a distinctive class of porous materials that have widely been used for several applications like the detection of small hazardous molecules, capturing and sequestering small molecules, heterogeneous catalysis, energy storage, gas separation, and water splitting and harvesting, etc. − Thus, the capture of molecular and ionic iodines has been demonstrated to a good extent by these materials. However, only a handful of reports have been published with adequate iodine capture values from the vapor phase as well as the solution phase. − Most of the robust and stable materials that are suitable for such iodine capture studies were synthesized under drastic conditions. For instance, MOFs and COFs are synthesized solvothermally, under high temperature and vacuum conditions, or through microwave treatment or by the use of additional reagents, like modulators and acids/bases. − It is known that taking a methodology to perform a large-scale application requires great effort, for which there is a requirement of simplification in synthetic methods.…”

Synthetic Control of Thorium Metal‐Organic Frameworks for Sequencing and Sensing of Radioiodine Species

“…The uptake capacity of Th‐BITD‐1 is comparable to those of UiO‐66 and ZiF‐8 and is higher than values of most Th‐MOFs, including Th‐UiO‐66‐(NH 2 ) 2 , Th‐TCBPA, Th‐BDAT, and so on (Table S5). [ 43‐45 ] The mole uptakes of iodine were converted to be 4.9 and 3.1 I 2 molecules per Th for Th‐BITD‐1 and Th‐BITD‐2 , respectively, rendering Th‐BITD‐1 as a more efficient adsorbent for iodine vapor.…”
