SCM-39, the direct synthesized ATS aluminosilicate zeolite as a promising solid acid catalyst

ATS-type zeolite is used to be known as aluminophosphate or borosilicate. Its aluminosilicate analog was supposed to be a promising solid acid material, which is still of great challenges to synthesize directly. Herein, we report a new zeolite, SCM-39, as the first directly synthesized ATS aluminosilicate, using commercially available 4-pyrrolidinopyridine as OSDA. SCM-39 exhibits great hydrothermal stability and possesses a large amount of acid sites. In comparison with MOR zeolite, it showed better catalytic performances in the disproportionation of toluene and self-condensation of cyclohexanone.

Automated summary

A new zeolite, SCM-39, has been successfully synthesized directly as the first aluminosilicate analog of ATS-type zeolite. SCM-39 exhibits excellent hydrothermal stability and abundant acid sites, and shows superior catalytic performances in the disproportionation of toluene and self-condensation of cyclohexanone compared to MOR zeolite.
