Pore opened zeolite nanosheets and their suspensions and methods and uses related thereto
Abstract
Methods for forming two-dimensional (2D) zeolite nanosheets include exposing a multi-lamellar (ML) zeolite material including an organic structure directing agent (OSDA) to a mixture including sulfuric acid and hydrogen peroxide under conditions sufficient to remove substantially all of the OSDA from the ML zeolite material; and after exposing the ML zeolite material, treating a solution containing the ML zeolite material to sonication and/or mixing under conditions sufficient to substantially exfoliate layers of the ML zeolite to obtain porous two-dimensional zeolite nanosheets that are substantially free of the OSDA. In some cases, without further treatment such as secondary growth of the zeolite coating layer, a deposit of the OSDA-free nanosheets on polymer support exhibits hydrocarbon isomer selectivity.
