Promising Strategy to Synthesize ZSM-5@Silicalite-1 with Superior Catalytic Performance for Catalytic Cracking Reactions

Abstract: with regular morphology was prepared through an innovative tandem synthesis strategy for the first time, which combined the insertion of almost all aluminum sites by organotemplate-free synthesis and the sequential crystallization of residual silica sites by organotemplate-oriented synthesis. Samples with different Si and Al distributions could be synthesized by adjusting the tandem synthesis process, including temperature, time, Na 2 O/SiO 2 , etc. The obtained Si-rich-ZSM-5 and conventional C-ZSM-5 with a si… Show more

“…Recently, the synthesis of ZSM5@silicalite-1 core–shells was achieved using a novel tandem synthesis approach . This innovative strategy involved two sequential steps: the incorporation of nearly all aluminum atoms through organic-template-free (or organotemplate-free) synthesis, followed by the crystallization of the remaining silicate precursor using organic template synthesis.…”

“…Recently, the synthesis of ZSM5@silicalite-1 core–shells was achieved using a novel tandem synthesis approach. 10 This innovative strategy involved two sequential steps: the incorporation of nearly all aluminum atoms through organic-template-free (or organotemplate-free) synthesis, followed by the crystallization of the remaining silicate precursor using organic template synthesis. Referring to the organic-template-free synthesis, chemicals including colloidal silica, Al 2 (SO 4 ) 3 ·18H 2 O, NaOH, H 2 O, and seeds were mixed and stirred at room temperature and then transferred to a stainless-steel autoclave for dynamic crystallization for 8 h at 170 °C.…”
