About six years after the first publication, ordered mesoporous oxides can
be prepared by a variety of procedures and over a wide range of composition
s using various different surfactant templates. The mechanisms of formation
, although still a matter of discussion, are understood in principle, and t
he macroscopic morphology as well as the orientation of the pores can be co
ntrolled in fortunate cases. However, still lacking are groundbreaking deve
lopments in the field of applications, either in catalysis or other areas.
The state-of-the-art in the synthesis, characterization and application of
ordered mesoporous oxides will be covered in this review. (C) 1999 Elsevier
