1. A method for the preparation of co-crystallized MFI/MOR zeolite comprising:
forming a homogeneous aqueous mixture of a silica source, an aluminum source, an alkali metal source, an optional structure directing agent, and an effective amount of water-soluble oxidized disulfide oil (ODSO); and
heating the homogeneous aqueous mixture under conditions and for a time effective to form a crystalline zeolite as precipitate suspended in a supernatant, wherein the precipitate comprises co-crystallized MFI/MOR zeolite.
