The South China Block(SCB) was formed through the Neoproterozoic amalgamation of the Yangtze Block(YB), the Cathaysia Block(CB), and the accreted components of the Jiangnan orogenic belt(JNO), it is bounded by the Jiangshan–shaoxing–Pingxiang fault(JSPF) and the Jiujiang–Shitai–Jishou fault(JSJF)(Yao et al., 2019). The SCB has undergone a series of complex geological events, including Paleozoic orogeny, Mesozoic collisions with the North China Craton(NCC) and the Indochina Block, as well as the intracontinental orogeny, leading to extensive lithospheric modifications and magmatic activities(Zhang H J et al., 2023; Fig. 1).

The separation of radionuclides is critical for the sustainable development of nuclear energy. It is urgent to design and prepare functionalized materials for efficient radionuclides separation. Porous materials are considered excellent candidates for the separation of radionuclides under complex conditions due to their high specific surface areas, tunable pore structures and controllable functionalities. In this review, we summarized the design, preparation and functionalization of porous materials and their application for separation of radionuclides in the past five years, discussed the separation performance and analyzed the structure-activity relationship between various radionuclides and porous materials, and systematically clarified their characterization and mechanism of different type porous materials. We also introduced the detection, irradiation and chemical toxicity of different reflective radionuclides.
