Zusammenfassung: | The invention discloses a synthesis method of a Coffin morphology ZSM-5 molecular sieve with an adjustable crystal face, and belongs to the field of inorganic chemistry. In a template-free system, different from conventional'molecular sieve seed crystal ', the ZSM-5 molecular sieve with the adjustable (011) crystal face and the Coffin morphology is prepared by adopting a'seed crystal-like' measure and taking a'structural unit mor 'as a'seed crystal-like'. In the preparation process, alkalinity [NaOH]/[SiO2] and water amount [H2O]/[SiO2] are changed, crystal face exposure of the Coffin morphology ZSM-5 molecular sieve (011) and controllable adjustment of the crystal face size are realized, and the method has guiding significance for effectively controlling the crystal face of the ZSM-5 molecular sieve. The controllable preparation measure of the crystal face (011) on the Coffin morphology ZSM-5 molecular sieve developed by the invention not only is low in cost and simple to operate, but also has no special gen |
