Abstract: The oxidation of cyclohexane with molecular oxygen
in the presence of isobutyraldehyde catalyzed by nanostructured iron
and cobalt oxides and iron oxide supported on titania has been studied.
Nanostructured cobalt oxide on MCM-41 is found to be efficient for catalytic
aerobic epoxidation of olefins.
