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.
