N2 - Hierarchical ZSM‐5 zeolite with uniform mesopores was synthesized with a simple cetyltrimethylammonium (CTA+) template, which acted as a bifunctional surfactant in a RbOH‐based alkaline synthesis gel. Rb+ plays a key role in obtaining uniform mesopores within ZSM‐5 crystals. The structural, textural properties and the acidity were characterized by XRD, Ar physisorption, TEM, as well as CO IR and 27Al MAS NMR spectroscopy. These data point to partial retention of the initial mesoscale ordered texture of the precursor in the final zeolite. These textural properties result in a strongly improved catalytic performance in the methanol conversion reaction compared to bulk zeolite.
