A new mesoporous manganese oxide pillared with double layers of alumina
The flocculation of colloidal nanosheets of MnO2 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.
