Ultra-fast uranium capture via the synergistic interaction of the intrinsic sulfur atoms and the phosphoric acid groups adhered to edge sulfur of MoS2

Molybdenum sulphide clusters as redox-active supports for low-valent uranium

“…While in both cases, the uranium centre binds to cluster surface in a mode similar to that predicted for uranyl binding at the basal plane of MoS 2 , the contacts between the model of the MoS 2 surface and the uranium centre are much shorter than predicted for UO 2 2+ and MoS 2 . 6–8 These observations indicate a more robust interaction between uranium and the molecular model of the [MoS] surface. We hypothesize this is due to discrepancies in oxidation state of the uranium ions; the low-valent uranium centres investigated in this work bind more strongly to the surface of the metalloligand.…”

“…Results have emphasized the benefit of soft–soft interactions between the sulphur donors and uranium atoms to promote selectivity of uranium uptake over harder impurity ions, as well as for enhanced electronic communication between the material and the actinide ion. 5–12…”

“…The observed binding mode effectively models coordination of actinide centres to the basal plane of MoS 2 proposed by density functional theory. 7–9…”

Hollow S-Doped ZnFe2O4 Microcubes with Magnetic Separability for Photocatalytic Removal of Uranium(VI) under Different Light Intensity

“…The Fukushima nuclear accident, on the other hand, is estimated to have released around 520 PBq of radionuclides due to its high solubility and mobility, as seen in the aftermath of the March 11, 2011 earthquake. The failure to contain the spread of released radionuclides, such as 235 U/ 238 U and 236 U, led to contamination of an area roughly 14,000 km 2 , necessitating the evacuation of about 100,000 residents . Addressing uranium resource scarcity and the discharge of uranium-laden waste liquids is paramount for nuclear industry sustainability and ecological conservation.…”

Extraction of Uranium by a Cheap Phosphite-Derived Polymer under Light Condition

“…Phosphate esters have attracted much attention because of their unique affinity to uranium. − Porous organic polymer, due to its adjustable pore size and high specific surface area, can be loaded with phosphate groups onto the skeleton by direct modification or postmodification to achieve the adsorption of uranium. , Hua et al, − by preparing an imprinting chamber with a phosphonate ligand on a silica medium to realize the selective adsorption of uranium, also functionalized silica and MoS 2 sheet with phosphoric acid to achieve the efficient adsorption of uranium in aqueous solutions. Yan et al reported a postsynthetic modification method to synthesize two benzoxazole-linked covalent organic frameworks decorated with abundant phosphonic groups for uranium adsorption.…”
