Examples
example 1
[0040] Example 1: Dissolve 2mL of tetra-n-butyl titanate in 30mL of absolute ethanol to form mixed solution A, and stir. Add 10 mL of concentrated nitric acid dropwise to mixed solution A to form mixed solution B, and stir.
[0041] The mixed solution B was slowly added dropwise into 50 mL of deionized water, stirred evenly and left to stand for a period of time to form Sol C.
[0042] Sol C is slowly added dropwise onto the prepared supported Y-type molecular sieve membrane under the condition of stirring until the whole molecular sieve membrane support is submerged. After standing for 48 hours, rinse with deionized water and dry. Put it into 40mL of n-butylamine, let it stand for 12h, rinse it with deionized water, and dry it. Finally, put it into a muffle furnace and bake at 800° C. for 2 hours to prepare a Y-type molecular sieve membrane-loaded nitrogen-doped titanium dioxide.

example 2
[0044] Example 2: Dissolve 5 mL of tetra-n-butyl titanate in 10 mL of absolute ethanol to form mixed solution A, and stir. Add 6 mL of concentrated nitric acid dropwise to mixed solution A to form mixed solution B, and stir.
[0045] The mixed solution B was slowly added dropwise to 40mL deionized water, stirred evenly and left to stand for a period of time to form Sol C.
[0046] Sol C is slowly added dropwise onto the prepared supported Y-type molecular sieve membrane under the condition of stirring until the whole molecular sieve membrane support is submerged. After standing for 12 hours, rinse with deionized water and dry. Then put it into 30mL of n-butylamine, let it stand for 48h, rinse it with deionized water, and dry it. Finally, put it into a muffle furnace and bake at 300° C. for 10 hours to prepare a Y-type molecular sieve membrane-loaded nitrogen-doped titanium dioxide.

[0048] Example 3: Dissolve 10 mL of tetra-n-butyl titanate in 20 mL of absolute ethanol to form mixed solution A, and stir. Add 2 mL of concentrated nitric acid dropwise to mixed solution A to form mixed solution B, and stir.
[0049] Slowly add B to 60mL deionized water dropwise, stir evenly and let it stand for a while to form Sol C.
[0050] Sol C is slowly added dropwise onto the prepared supported Y-type molecular sieve membrane under the condition of stirring until the whole molecular sieve membrane support is submerged. After standing for 36 hours, rinse with deionized water and dry. Then put it into 40mL of n-butylamine, let it stand for 36h, rinse it with deionized water, and dry it. Finally, put it into a muffle furnace and bake at 500° C. for 5 hours to prepare a Y-type molecular sieve membrane-loaded nitrogen-doped titanium dioxide.
