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.
