✦ Synopsis

A monoolein-based bicontinuous cubic phase was used as a template for the preparation of a mesoporous alumina. 1 H NMR was used to identify the cubic liquid crystalline region. Transmission electron microscopy images showed the crystallite sizes to be in the range of 3-10 nm and it is these crystallites which appear to be connected with each other in an amorphous matrix in between. The Brunauer-Emmett-Teller specific surface area of the material was 236 m 2 /g and had a pore volume of 0.188 cm 3 g -1 . The material was mainly mesoporous, having an average pore diameter of 38 Å.
