1. A method for synthesis of pure silica zeolite comprising:
forming a homogeneous aqueous mixture of an effective amount of water-soluble oxidized disulfide oil (ODSO), and precursors and reagents effective for synthesis of pure silica zeolite; and
heating the homogeneous aqueous mixture under conditions and for a time effective to form a precipitate suspended in a supernatant, wherein the precipitate comprises pure silica zeolite.
