The preparation of hierarchical zeolites usually involves hard or soft templates and multiple synthesis steps, which often prohibit their industrial uses. One way to overcome these issues is to build hierarchical zeolites using repetitive branching, where the intrinsic growth patterns of zeolites, instead of porogenic templates, are utilized. This paper expands on an earlier report to unravel the sequence of events leading to this repetitive branching process for the framework type MFI zeolite structure using small‐angle X‐ray scattering and transmission electron microscopy. Moreover, adsorption and transport properties of the hierarchical zeolite are probed using 2,2‐dimethylbutane, n ‐hexane, and n ‐nonane.
