Embodiment 1
[0024] Weigh 0.1g metal node as Fe 3+ The dry powder of MIL-100 is placed in a glass bottle and placed in isolation from 2mL N,N'-dimethylformamide to ensure that the two do not touch. After sealing, place it in an oven at 250°C for 10 hours. After cooling, you can get Fe 2+ Metal-organic framework adsorbents at metal nodes.
Embodiment 2
[0026] Weigh 0.1g metal node as Fe 3+ The dry powder of MIL-100 is placed in a glass bottle, separated from 2mL formamide to ensure that the two do not touch, sealed and placed in an oven at 250°C for 10h, and after cooling, the Fe-containing 2+ Metal-organic framework adsorbents at metal nodes.
Embodiment 3
[0028] Weigh 0.1g metal node as Fe 3+ The dry powder of MIL-100 is placed in a glass bottle, separated from 2mL of acetamide to ensure that the two are not in contact, sealed and placed in an oven at 250°C for 10 hours, and after cooling, the Fe-containing 2+ Metal-organic framework adsorbents at metal nodes.
