Synthesis of hierarchical Beta using piperidine based multi-ammonium surfactants

Hierarchical Beta zeolite was prepared using piperidine based structure directing agents having at least two ammonium groups in their structure. Materials exhibited very high surface area (approximate to 1050 m(2) g(-1)), pore volume (2.7 mL g(-1)), and catalytic activity hitherto reported in the literature. A density functional theoretical study shows that a suitable special orientation of piperidine rings in the structure directing agents is responsible for the formation of hierarchical Beta.
