Environmental contamination by U(VI) from radioactive wastewater has become a challenging concern in the development of nuclear energy. A highly efficient recovery is essential for environmental remediation and can mitigate depletion conventional uranium resources. This study describes synthesis single-layered Ti3C2TX nanosheets chemical exfoliation using ultrasonography. The structure promoted high sorption capacity 3.20 mmol/g (distribution constant Kd > 104 mL/g) excellent selectivity mine that contained numerous coexisting ions. Fragmentation micron-scale to nanoscale upon uranyl was detected small-angle X-ray scattering transmission electron microscopy. Extended absorption fine spectroscopy, photoelectron density functional theory calculations demonstrated groups coordinated with terminal −OH −F on surface nanosheets. These findings provide imperative insights into design application nanomaterials effectively treat uranium-contaminated wastewater.
