Embodiment 1
[0020] Example 1, a preparation method of a nanoscale molecular sieve@graphene oxide coupling material mentioned in the present invention, comprising the following steps:
[0021] At room temperature, mix silica sol, sodium hydroxide and deionized water to prepare silicon source solution, the mass fraction of silica sol is 22%, and the mass fraction of sodium hydroxide is 21%; mix aluminum powder, sodium hydroxide and deionized water to prepare Aluminum source solution, the mass fraction of aluminum is 3.4%, and the mass fraction of sodium hydroxide is 32%. Place the silicon source and aluminum source solutions in a mixture of ice and water until the two solutions reach 0°C, add the aluminum source solution to the silicon source solution drop by drop, and stir for 24 hours at a speed of 800 rps. The mixed solution was centrifuged and washed to pH=8, and freeze-dried to obtain the molecular sieve amorphous precursor product. The obtained amorphous precursor was stirred and mix...
