Abstract A new super‐microporous aluminosilicate having a high aluminium content (Si/Al ca. 1) has been prepared through a surfactant‐assisted procedure with the use of a commercially available binary precursor (di‐ sec ‐butoxyaluminooxytriethoxysilane) as a single source of both Al and Si. The formation of super‐micropores is a result of a significant network shrinkage associated with the thermal elimination of the surfactant. This solid has been studied by X‐ray powder diffraction, electron microscopy, nuclear magnetic resonance spectroscopy and porosimetry. A preliminary analysis of the acidity and the catalytic activity of the super‐microporous solid for the selective catalytic reduction of NO x is also presented. (© Wiley‐VCH Verlag GmbH & Co.
