Examples
Embodiment 1
[0041] Get selected 10 grams of molecular sieves, join in the reactor after pretreatment, ferric dichloride (FeCl 2 4H 2 O) dubbed 2×10 -3 The aqueous solution of M was 0.5 liters, stirred for more than 5 hours to fully load the metal ions. Continue to wash with water without iron ions and dry for later use. Mix 2 g of α, α'-bipyridine with the prepared molecular sieve, grind it thoroughly, place it in a closed container, and heat it to 90° C. in a tube furnace for 24 hours to react. Wrap the obtained crude product with filter paper, and use CH 2 Cl 2 As a solvent, use a Soxhlet extractor to remove excess ligands, heat and dry at 50°C under nitrogen protection before use.
Embodiment 2
[0043] Prepare 10 grams of molecular sieves loaded with ferrous iron with Example 1, and take by weighing 1,10-phenanthroline (C 12 h 8 N 2 ·H 2 (0) 3 grams, mixed evenly, placed in a closed container, heated to 90°C in a tube furnace to react for 24 hours. Wrap the prepared crude product with filter paper, use acetone as a solvent, remove excess ligands with a Soxhlet extractor, heat and dry at 50°C under nitrogen protection, and then use it.
Embodiment 3
[0045] 10 grams of ferrous iron-loaded molecular sieves were prepared in the same manner as in Example 1, and 2 grams of Schiff bases were weighed, mixed evenly, placed in a closed container, and heated to 90° C. in a tube furnace for 24 hours to react. Wrap the obtained crude product with filter paper, and use CH 2 Cl 2 As a solvent, use a Soxhlet extractor to remove excess ligands, heat and dry at 50°C under nitrogen protection before use.
