Example Embodiment
[0033] Example 1:
[0034] First, use ethyl acetate solvent and imidazole as functional monomers to synthesize titanium dioxide-mesoporous polymer nanoporous composite visible light catalytic material, namely PDVB-VI-TiO 2 -xs (where xs represents the molar ratio of titanium species to imidazole in the material).
[0035] Add 2.0 g DVB, 0.72 g 1-vinylimidazole (VI) to the mixed solution containing 0.065 g AIBN and 25 mL ethyl acetate, then add 2.5 mL n-butyl titanate (TBOT), stir at room temperature for 3 hours, 100 Hydrothermal treatment at ℃ for 24 h, a brown-yellow block solid was obtained. In order to fully crystallize the titanium dioxide in the material, open the lid of the hydrothermal treatment reactor, add 2-3mL of water, and continue the hydrothermal treatment at 160℃ for 24 hours, take it out, open the lid, and volatilize the solvent to obtain PDVB-VI-TiO 2 -0.92. During the synthesis process, DVB / AIBN / VI / TBOT / ethyl acetate (molar ratio) is 1 / 0.026 / 0.5 / 0.46 / 16.7.
Example Embodiment
[0036] Example 2:
[0037] Ethyl acetate solvent and imidazole are used as functional monomers to synthesize titanium dioxide-mesoporous polymer nanoporous composite visible light catalytic material, and the content of titanium species in the material is adjusted.
[0038] Add 2.0 g DVB, 0.72 g 1-vinylimidazole (VI) to the mixed solution containing 0.065 g AIBN and 25 mL ethyl acetate, then add 1.25 mL n-butyl titanate (TBOT), stir at room temperature for 3 hours, 100 Hydrothermal treatment at ℃ for 24 h, a brown-yellow block solid is obtained. In order to fully crystallize the titanium dioxide in the material, open the lid of the reaction kettle after hydrothermal treatment, add 2-3 mL of water, and continue the hydrothermal treatment at 150℃ for 24 hours, take it out and open Cover, evaporate the solvent, and get PDVB-VI-TiO 2 -0.46. During the synthesis process, DVB / AIBN / VI / TBOT / ethyl acetate (molar ratio) is 1 / 0.026 / 0.5 / 0.23 / 16.7.
Example Embodiment
[0039] Example 3:
[0040] In the process of synthesizing titanium dioxide-mesoporous polymer nanoporous composite visible light catalytic material, the synthetic solvent in the process of material synthesis is adjusted.
[0041] Add 2.0 g DVB, 0.72 g 1-vinylimidazole (VI) to a mixed solution containing 0.065 g AIBN and 20-30 mL tetrahydrofuran, then add 2.5 mL n-butyl titanate (TBOT), stir at room temperature for 3 hours, 100 Hydrothermal treatment at ℃ for 24 h, a brown-yellow block solid is obtained. In order to fully crystallize the titanium dioxide in the material, open the lid of the reaction kettle after hydrothermal treatment, add 2-3mL of water, and continue the hydrothermal treatment at 150℃ for 24 hours, take it out and open Cover, evaporate the solvent, and get PDVB-VI-TiO 2 -0.92. DVB / AIBN / VI / TBOT / tetrahydrofuran in the synthesis process is 1 / 0.026 / 0.5 / 0.46 / 16.7.
