虽然二维早期过渡金属碳化物和碳氮化物（MXenes）近年来引起了广泛的兴趣，但它们在各种科学应用中的卓越能力一直受到多层结构内部非常狭窄的层间空间的影响。在这里，我们证明了Ti3C2Tx通过水合插层策略对放射性核素去除的前所未有的大吸附能力增强。通过合理控制层间空间，确定了具有代表性的锕系元素U（VI）在多层Ti3C2Tx中的囚禁潜力。
Though two-dimensional early transition metal carbides and carbonitrides (MXenes) have attracted extensive interest recently, their superb abilities in various scientific applications always suffer from the very narrow interlayer space inside the multilayered structure. Here we demonstrate an unprecedented large adsorption capacity enhancement of Ti3C2Tx toward radionuclide removal via a hydrated intercalation strategy. By rational control of the interlayer space, the potential for imprisoning the representative actinide U(VI) inside multilayered Ti3C2Tx was also confirmed.
