A new synthesis technique has been developed to prepare a family of coherently grown composites of at least two zeotypes. Examples of these composites are represented by the empirical formula. NanMmk+TtAl1-xExSiyOz where “n” is the mole ratio of Na to (Al+E), M represents at least one metal of zinc, Group 1, Group 2, Group 3 and the lanthanide series of the periodic table, and any combination thereof, “m” is the mole ratio of M to (Al+E), “k” is the average charge of the metal or metals M, T is the organic structure directing agent or agents, “t” is the mole ratio of N from the organic structure directing agent or agents to (Al+E), and E is a framework element such as gallium. The synthesis technique is the Layered Conversion Synthesis technique. |
