Synthesis, Characterization, and Catalytic Activity of a Large-Pore Tridirectional Zeolite, H-ITQ-7

Over 30 years since the first tridirectional zeolite: The new ITQ-7 material is catalytically active, high in silica, and has large pore sizes. More significantly, T-ITQ-7 material can be prepared by a new synthetic process which allows atomic substitution of the Si in the framework for T atoms boron, aluminum, or germanium. The Ge-ITQ-7 variant shows a markedly different mean crystallite size. The catalytic activity of these materials is demonstated by cracking n-decane.
