The flocculation of colloidal nanosheets of MnO 2 with Al 13 Keggin ions produces a novel pillared structure with a double‐layer arrangement of Al 13 species, which exhibits a large intersheet spacing of 2.3 nm and a well‐defined mesoporosity. The Figure shows a schematic representation of the formation process.
