The effective capture of radioactive iodine vapor is crucial for radiation safety during spent fuel reprocessing. However, current materials used for iodine vapor capture have limitations such as low adsorption efficiency and poor stability, which hinder the effectiveness. To address this issue, an efficient, stable, recoverable and heterogeneous MOF-on-MOF [NH2-MIL-101-on-NH2-UiO-66] adsorbent was prepared using the epitaxial growth strategy. The adsorbent was extensively characterized with various technologies including FT-IR, XPS and XRD, and batch experiments were conducted to evaluate the...
