Highly efficient and selective Sr²⁺ capture using robust two-dimensional MOF nanosheets decorated with cage-like cavities.

ABSTRACT: The urgent need for efficient extraction of radio-strontium (Sr) from complex aquatic environments arises from its extreme radiotoxicity to both ecosystems and human health, which remains a significant challenge. In this study, we developed an ultrathin 2D Cu-MOF-COOH nanosheet with cage-like cavities for strontium separation. Incorporating the permanent cavity structures on the MOF nanosheet can fully utilize its structural characteristics of a largely exposed surface area and accessible adsorption sites in pollutant removal, and the comprehensive interactions between pollutants with the active sites and cavities on the exposed surfaces can achieve highly selective and efficient capture. Consequently, the Cu-MOF-COOH nanosheet exhibited superior capture performances, in terms of removal k
