Embodiment Construction
[0048] This example provides a method for synthesizing a copper polyphenol-triazine supramolecular network structure nanocomposite, that is, a method for preparing a CTP@Cu-PP catalyst. Include the following steps:
[0049] 1) Weigh 1,3,5-triazine-2,4,6-triamine and 1,3,5-cyclohexanetrione according to the molar ratio of 3:1, disperse them in methanol and heat at 40 °C Ultrasonic for 1.5 h, the resulting product was washed several times with ethanol and centrifuged, and vacuum-dried at 60 °C for 15 h to obtain the covalent triazine-based organic polymer CTP;
[0050] 2) Disperse 0.3 g of CTP prepared in step 1) in 30 ml of plant polyphenol solution (12 mmol / L), and perform ultrasonication for 20 min at room temperature;
[0051] 3) Disperse 60 mg of copper sulfate pentahydrate in 30 ml of plant polyphenol solution (12 mmol / L), sonicate for 10 min at room temperature, pour the sonicated solution into the sonicated CTP solution in step 2), Stir the reaction at room temperature...
