A two-dimensional zeolite with the topology of MWW sheets has been obtained by direct synthesis with a combination of two organic structure-directing agents. The resultant material consists of approximately 70% single and double layers and displays a well-structured external surface area of about 300m(2)g(-1). The delaminated zeolite prepared 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.
