Cu/Bi-NC Composites Derived from Bimetallic MOFs for Efficient and Stable Capture of Multiform Iodine
With the popularization of nuclear energy in the field of energy application, the effective removal of radioactive iodine isotopes is crucial for the long-term development of nuclear energy. In this paper, bimetallic MOFs with different Cu/Bi ratios were synthesized by a simple solvothermal method, and a bimetallic nano-adsorbent Cux/Bi10−x-NC was prepared by one-step calcination. Adsorption experiments show that Cux/Bi10−x-NC exhibits excellent adsorption performance for iodide ions, gaseous iodine, and I2 in cyclohexane solution, with the maximum adsorption capacities reaching up to 484.08 and 233.11 mg g−1, respectively. Through the characterization of the material system before and after adsorption, this excellent adsorption performance is attributed to the synergistic effect between Cu and Bi, as well as the highly dispersed adsorption active sites derived from the MOF template. Therefore, the prepared Cux/Bi10−x-NC has great potential in the efficient and stable capture of various forms of iodine.
