Synthesis method of uniform nano ZSM-5 molecular sieve |
| abstract |
The invention belongs to the technical field of zeolite molecular sieve synthesis, and particularly relates to a novel method for preparing a uniform nano ZSM-5 molecular sieve by two-step wetting. The method mainly uses precursor mother liquor to wet the surface of silica sol, then forms working solution to wet the surface of crystal seed gel, and prepares the ZSM-5 zeolite by one step by adding and stirring in the crystallization process. The invention can greatly reduce the dosage of the template agent and reduce the environmental pollution. The sample XRD shows that the obtained product is a ZSM-5 molecular sieve and has good crystallinity. SEM shows that the particle size of the nano zeolite is uniformly distributed. |
