Synthesis and catalytic activity of UZM-12
UZM-12 is a microporous crystalline aluminosilicate with ERI topology synthesized via the Charge Density Mismatch approach. The Charge Density Mismatch approach features synthesis from clear aluminosilicate solutions with high organic template content that are subsequently treated with crystallization inducing solutions. The solution containing low amounts of alkali and a higher charge density organic “crystallization template, yields UZM- 12 with Si/Al > 5.5 and nano- to micron-sized crystallites of spherical, plate or rod morphology depending on crystallization template, K+/Al ratio and synthesis conditions. Crystallization templates include the diquat-6, diquat-4, and benzyltrimethylammonium cations. The thermal, steam stability, and acid properties of H-UZM-12 were determined using the combinatorial heptane microreactor.
