Ultra-high yield of a silicoaluminophosphate zeolite is reported with a facile and cost-effective acid-assisted method. The lower gel pH due to the addition of an acid enhances the activity of the phosphorus species and promotes the polymerization of

ZSM-5 nanosheet (NS) has an optimal diffusivity due to b-axis oriented two-dimensional structure, but the extra large external acidity results in the deactivation of the catalyst in methanol to propylene (MTP) reaction. The seed-fused ZSM-5 nanosheet

Herein, a specific core–shell MFI zeolite was designed for the methanol to propylene (MTP) reaction. The core–shell structure of Al-ZSM-5@B-ZSM-5 and Al-ZSM-5@silicalite-1 were easily obtained via a two-step procedure, in which Al-ZSM-5 aggregate

We demonstrate an efficient method for the assembly of hierarchical NaY aggregates by using a modified structure-directing agent (SDA) in an extremely dense aqueous system at 373K. By introducing the dimethylhexadecyl[3-(trimethoxysilyl)propyl] ammon

Two kinds of ZSM-5 zeolites with various SiO2/Al2O3 ratios were synthesized using ethanol (EtOH) or tetrapropylammonium bromide (TPABr) as the template respectively and their physicochemical properties were investigated extensively. Different ZSM-5 m
