In order to improve the uptake capacity of MIL-101 for iodine, Cu nanoparticles doped MIL-101 were successfully synthesized through a facile method. The obtained Cu/MIL-101 was characterized by SEM, XRD, EDS, TEM, IR, TGA and BET to examine the chemical and thermal stabilities. The capture experiments for the adsorbents showed that the capture capacity of Cu/MIL-101 for volatile iodine is 342 wt%, which is higher than that of pure MIL-101. An I₂ uptake of 342 wt% is the highest value reported among metal-organic frameworks. Furthermore, Cu/MIL-101 has a cycle ratio of 95% after three cycles and exhibits a better cyclicity than pure MIL-101. Meanwhile, Cu/MIL-101 shows an excellent reversible adsorption of iodine in solution.

为了提高MIL-101对碘的吸收能力，通过一种简便的方法成功地合成了掺杂MIL-101的Cu纳米粒子。通过SEM，XRD，EDS，TEM，IR，TGA和BET对所得的Cu / MIL-101进行表征，以检验其化学稳定性和热稳定性。吸附剂的捕获实验表明，Cu / MIL-101对挥发性碘的捕获能力为342  wt％，高于纯MIL-101的捕获能力。342 wt％的I ₂吸收 是金属有机骨架中报道的最高值。此外，Cu / MIL-101在三个循环后的循环比为95％，并且比纯MIL-101具有更好的循环性。同时，Cu / MIL-101对溶液中的碘具有极好的可逆吸附性。
