Abstract
Metal-organic frameworks (MOFs) hold the distinctive advantages of high specific surface areas, tunable pore diameter, and easy postmodification, endowing them with unique performances on radioactive waste remediation. In this chapter, we summarize the recent progress on the sequestration and separation of radionuclides that are related to the nuclear fuel cycle by MOFs. The synthesis routes of functionalized MOF sorbents and the adsorption performances (i.e., capacity, kinetics, and selectivity) toward a series of radionuclides including 137Cs, 90Sr, 238U, 232Th, 79Se, 99Tc, 129I, 133Xe, and 85Kr as well as the uptake mechanism are briefly summarized. The current challenges of radioactive waste sequestration by MOF-based sorbents and the future perspectives are also underlined.
