Direct Dual-Template Synthesis of MWW Zeolite Monolayers

A two-dimensional zeolite with the topol. of MWW sheets has been obtained by direct synthesis with a combination of two org. structure-directing agents. The resultant material consists of approx. 70 % single and double layers and displays a well-structured external surface area of about 300 m2 g-1....

Sumario:A two-dimensional zeolite with the topol. of MWW sheets has been obtained by direct synthesis with a combination of two org. structure-directing agents. The resultant material consists of approx. 70 % single and double layers and displays a well-structured external surface area of about 300 m2 g-1. The delaminated zeolite prepd. by means of this single-step synthetic route has a high delamination degree, and the structural integrity of the MWW layers is well preserved. The new zeolite material displayed excellent activity, selectivity, and stability when used as a catalyst for the alkylation of benzene with propylene and found to be superior to the catalysts that are currently used for producing cumene.
