Embodiment 1
[0034] 1) Dissolve 0.64g of terephthalonitrile and 0.64g of 2,6-pyridinedicarbonitrile in 60mL of dichloromethane organic solvent, stir and fully dissolve at room temperature to obtain a dispersion;
[0035] 2) Put the dispersion obtained in step 1) in a round bottom flask, put it in an oil bath, add 10mL of trifluoromethanesulfonic acid, heat to reflux, and stir at 60°C for 40h. After the reaction, put The reaction solution was cooled to room temperature;
[0036]3) Pour the cooled reaction solution in step 2) into a beaker containing 200mL of ultrapure water, and use a pipette to add concentrated ammonia water (the concentration of concentrated ammonia water is 0.5mol / L) drop by drop to adjust the pH value of the solution to 7. Suction filtration is then carried out, and the filter residue is washed with dichloromethane, ultrapure water and ethanol in sequence, and dried in vacuum to finally obtain the defective covalent triazine framework carrier material powder;
