Loading actinides in multi-layered structures for nuclear waste treatment: the first case study of uranium capture with vanadium carbide MXene.
ACS Appl. Mater. Interfaces. 2016, accepted. (The first two authors contributed equally to this work.)
Table of Content:
Efficient nuclear waste treatment and environmental management are important hurdles that need to be overcome if nuclear energy is to become more widely used. Herein we demonstrated the first case of using two-dimensional (2D) multilayered V2CTx nanosheets prepared by HF etching of V2AlC to remove actinides from aqueous solutions. The V2CTx material is found to be a highly efficient uranium (U(VI)) sorbent, evidenced by a high uptake capacity of 174 mg g-1, fast sorption kinetics, and desirable selectivity. Fitting of the sorption isotherm indicated that the sorption followed aheterogeneous adsorption model most probably due to the presence of heterogeneous adsorption sites. Density functional theory calculations, incombination with X-ray absorption fine structure characterizations, suggested that the uranyl ions prefer to coordinate with hydroxyl groups bonded to the V-sites of the nanosheets via forming bidentate inner-sphere complexes.
