A New Mesoporous Manganese Oxide Pillared with Double Layers of Alumina.
? (Al13)0.105MnO2�5H2O with Al13: [AlO4Al 12(OH) 24(H2O)12 ]7+ is synthesized by exfoliation/flocculation of colloidal H0.13MnO2�7H2O nanosheets with Al 13 Keggin ions.
The samples are characterized by XRD and TEM. The material exhibits a novel pillared
structure with double layers of Al13 polyoxocations, which generate a well-developed
structural mesoporosity with a remarkably high specific surface area. These features
render the material potentially useful for applications in the fields of catalysis and electrochemistry. ? (WANG, L.; EBINA, Y.; TAKADA, K.; KURASHIMA, K.;
