99Tc is one of the most problematic fission products in nuclear fuel cycle owing to its large inventory used fuel, long half-life, potential radiation hazard, high environmental mobility major species 99TcO4-, and redox-active nature. Ideally, 99TcO4- should be removed at first stage, when rods are dissolved highly concentrated nitric acid solution, which can substantially reduce interference with solvent extraction process through catalytic redox reactions key actinides diminish chance...
Removal of 99TcO4- from legacy defense nuclear tank waste at Savannah River Site is highly desirable for the purpose safety and environmental protection, but currently not achievable given extreme conditions including high alkalinity, ionic strength, strong radiation field. Herein, we present a potential solution to this long-term issue by developing two-dimensional cationic metal organic framework SCU-103, showing ultrahigh stability in alkaline aqueous media great resistance both β γ...
Aiming to improve the acetylene (C2H2) storage capability of MOFs, we successfully designed NJU-Bai 17, a new analogue MOF-505 with an inserted amide functional group which exhibits almost record high C2H2 uptakes 222.4 cm(3) g(-1) at 296 K and 273 under 1 bar. This result has been further supported by determination heat adsorption Grand Canonical Monte Carlo (GCMC) first-principle calculations.
Abstract We present a crystal engineering strategy to fine tune the pore chemistry and CH 4 ‐storage performance of family isomorphic MOFs based upon PCN‐14.

[Cu (L2)(H O) ] n (NJU‐Bai 41: NJU‐Bai for Nanjing University Bai's group), (L3)(H 42), (L4)(DMF) 43) we observed that volumetric capacity uptake values are influenced by subtle changes in structure chemistry.

A new approach of finely tuning multinuclear clusters metal–organic frameworks (MOFs) through symmetry-upgradingly isoreticular transformation was first presented and a bcu-type MOF, {[Cu4(μ4-O)Cl2(IN)4][CuCl2]}∞ (NJU-Bai35; NJU-Bai for Nanjing University Bai group), with cluster [Cu4(μ4-O)Cl2(COO)4N4] higher symmetry compared to the pristine successfully synthesized. The upgrading implemented on inorganic part triggers adjustment channels in NJU-Bai35 fit CO2 molecules, leading high...
Metal-organic framework (MOF) based heterostructures, which exhibit enhanced or unexpected functionality and properties due to synergistic effects, are typically synthesized using post-synthetic strategies. However, several reported strategies remain unsatisfactory, considering issues such as damage the crystallinity of MOFs, presence impure phases, high time energy consumption. In this work, we demonstrate for first a novel route constructing MOF heterostructures radiation-induced...

Abstract We disclose the intrinsic semiconducting properties of one largest mixed‐valent uranium clusters, [H 3 O + ][U V (U VI 2 ) 8 (μ ‐O) 6 (PhCOO) (Py(CH O) 4 (DMF) ] (Ph=phenyl, Py=pyridyl, DMF=N,N‐dimethylformamide) ( 1 ). Single‐crystal X‐ray crystallography demonstrates that U center is stabilized within a tetraoxo core surrounded by eight uranyl(VI) pentagonal bipyramidal centers. The oxidation states are substantiated spectroscopic data and magnetic susceptibility measurement....
Metal organic frameworks (MOFs) are a distinct family of crystalline porous materials finding extensive applications. Their synthesis often requires elevated temperature and relatively long reaction time. We report here the first case MOF activated by high-energy (1.5 MeV) electron beam radiation from commercially available electron-accelerator. Using ZIF-8 as representative for demonstration, this type can be accomplished under ambient conditions within minutes, leading to energy...
Defects in metal-organic frameworks (MOFs) can significantly change their local microstructures, thus notably leading to an alteration-induced performance sorption or catalysis. However, achieving de novo defect engineering MOFs under ambient conditions without the scarification of crystallinity remains a challenge. Herein, we successfully synthesize defective ZIF-7 through 60Co gamma ray radiation conditions. The obtained is defect-rich but also has excellent crystallinity, enhanced BET...

However, the efficient capture iodine, particularly methyl iodide, under conditions low concentration high-flow rate that are representative real-world scenarios remains underexplored. Herein, we adopted a "theory-first" strategy to design adsorbents with superior affinity iodide. rigorous theoretical calculations both...

Abstract Zeolites are a well‐known family of microporous aluminosilicate crystals with wide range applications. Their industrial synthetic method under hydrothermal condition requires elevated temperature and long crystallization time is therefore quite energy‐consuming. Herein, we utilize high‐energy electron beam irradiation generated by an accelerator as distinct type energy source to activate the formation reaction Na‐A zeolite. The initial efforts afford attractive process that can be...
