| titleOfInvention | A method for synthesizing mesoporous molecular sieves under neutral conditions |
| abstract | The invention relates to the technical field of molecular sieve synthesis technology, in particular to a method for synthesizing mesoporous molecular sieves under neutral conditions, comprising the following steps: (1) combining a nonionic surfactant and an anionic co-template agent cellulose ether Fully dissolving to obtain a composite template system; (2) adding the silicate solution obtained by dissolving sodium persulfate and silicon source into the composite template system to form a primary gel system of mesoporous molecular sieves; (3) adding aluminum source The mesoporous molecular sieve is obtained after being added into the primary gel system and fully reacted. In this application, an aluminum source is added during the synthesis process, and the traditional synthesis of metal-doped mesoporous molecular sieves under acidic conditions is changed to synthesis under neutral conditions, and cellulose ethers will form nematic phases in aqueous solutions during the heating process. Network structure, which restricts the interaction between surfactants through steric hindrance, thereby improving the dispersion of micelles, improving unit cell parameters, and obtaining mesoporous molecular sieves with large unit cell parameters. |
