MWW and PMWW were derived from the same precursor, MWW (P).

The other portion of MWW (P) was swollen according to the method developed by Maheshwari et al.,41 followed by pillaring of the swollen materials using the procedure reported by Barth et al.38 The resulting solid was treated using the same conditions as those for MWW to produce PMWW. A multilamellar MFI was synthesized using the method reported by Ryoo and co-workers,43 through a coherent assembly of the zeolite layer and the structure directing agent, a diquaternary ammonium surfactant with a relatively long hydrocarbon chain. Pillaring of multilamellar MFI was done as reported by Na et al.42 to produce PMFI, using a similar pillaring procedure to that of swollen MWW (P). The as-synthesized MWW and MFI zeolites were ion-exchanged four times using 1 mol L-1 aqueous NH4NO3 (weight ratio of zeolite to NH4NO3 solution = 1:10) at 353 K for 12 h and subsequently collected by vacuum filtration, washed with deionized (DI) water three times, and dried at 343 K overnight.
