摘要：

A surfactant-templated route to mesostructured forms of the transition alumina phases η-Al2O3 and χ-Al2O 3 is described. The surface areas and pore-size distributions of these novel forms of alumina are substantially improved with respect to those of conventional forms of these phases. Wormholelike pores are visible in the TEM image shown of mesostructured η-Al2O3. (Figure Presented). © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
