A kind of ZSM-5 hybrid nanosheet molecular sieve with medium silicon to aluminum ratio and preparation method thereof |
| abstract |
The invention discloses a medium-silicon-aluminum ratio ZSM-5 hybrid nanosheet molecular sieve and a preparation method thereof, belonging to the technical field of catalysts. The hybrid molecular sieve is composed of an internal microporous substrate and a nanosheet layer epitaxially grown on the outside of the microporous substrate, and its silicon-to-aluminum ratio is adjustable in the range of 100-300. The preparation method specifically includes the following steps: 1) adding small molecules Templating agent, silicon source, and aluminum source are dissolved in water to form a gel with uniform stirring; 2) Aging under stirring conditions; 3) Continuing to add long carbon chain amphiphilic surfactant solution and stirring uniformly; 4) Aging under stirring conditions; 5 ) to obtain the hybrid ZSM-5 molecular sieve after crystallization. The preparation method of the invention solves the limitation on the morphology of the molecular sieve with the silicon-aluminum ratio of the synthetic nano-sheet-block hybrid molecular sieve at the present stage, breaks through the limitation that the growth of the outer nano-sheet cannot be maintained due to the decrease of the silicon-aluminum ratio, and the prepared hybrid molecular sieve Synthetic molecular sieves have great application prospects in the field of catalysis such as the preparation of light olefins. |
